Top tips to optimally use conventional waterproofing techniques

While the first part of this two-part series examines conventional waterproofing systems and offers tips to use them for optimum effect, the second part will discuss modern waterproofing techniques. 

of building to prevent the ingress of water is an activity, which, perhaps is practiced in one form or the other, ever since the first building was built on earth. The methodology has been changing with the changes in the architectural designs and with the availability different building materials in construction.
 
In the initial stages when stone was the main building placed in position with mud or lime mortar the emphasis used to be to make the construction in such a way that the rainwater does not collect on the roofs. Hence old relied mainly on dome structures or slanting roofs. The slow speed of such construction and unaffordability of common man to build such structures for their own dwelling, made constant evolution and development in the technology.


 
With these developments the concepts of also changed. Now in present day construction wherein the ordinary and its blends with and slag materials has come to stay a lot of compatible alternatives are available for a builder to choose from various systems. Some systems are old and conventional but still practiced successfully and some are modern systems designed taking the material and structural behaviour into consideration.
 
There are some compounds, which are used in plastic concrete to make it less permeable to water. These compounds are known as integral compounds. They are based on plasticising and air-entrainment or water repellence principles. These are used as a good precautions when other factors such as good mix-design, proper mixing/placing, compacting/curing etc are taken care of. This subject of integral compounds requires in depth discussion hence will not be taken up here. Similarly there are some water proofing techniques for vertical surfaces. These techniques are also used for preserving heritage buildings by stopping/minimising the aging process of these buildings.
 
For solving water seepage problems, customers use both conventional as well as modern techniques.
 
Some of the old and conventional systems are as follows:


This system was developed during the initial stages of flat roof construction with lime mortar burnt clay brick pieces. This system involved laying lightweight mortar on the roof and spreading it to give gentle slopes for draining away the rainwater immediately. The mortar consisted of lightweight brick pieces as aggregates and ground brick with lime as binding matrix.
 
During British rule this system became more popular not because of its efficiency but because of its efficiency in keeping the interiors cool. Some applicators developed better skills in laying these systems, with neatly finished top with lines engraved on top of plastic mortar now known as IPS. Some practiced embedding broken tile or ceramic pieces in the plastic mortar and called it china mosaic.
 
This type of system remained most popular with multi-storeyed construction in all major cities. The system lasts up to 15 years if done by skilful applicators. This system may be considered more from its weather proofing abilities rather than its qualities. Once water starts entering into the brickbat coba the brick pieces absorb too much of water and the roof becomes an invisible pond of water continuously causing leakage and increasing burden on the roof slab. It will be highly beneficial if brick-bat coba is laid on a flexible membrane as water proofing as well as economical weather proofing can be achieved with this system.
 
treatment
Discovery of petroleum and its products and by-products has given the construction industry an indispensable product in the form of bitumen. Bitumen is more commonly used in the form of felt or flexible membrane formed by sandwiching jute fabric or fibreglass/polypropylene mats with chemically modified bitumen. These membranes are laid on the roofing over a bitumen primer. There are two types of membranes one is cold applied and the other hot applied which means one needs to heat the edges of the felt with a torch so that they melt and stick to the second layer in the overlap area.
 
On the roofs the bitumen felts have not been successful because of the unacceptable black appearance and inaccessibility of the terrace for other social uses. Technically it is not preferred because bitumen layer or felt on the terrace not only makes it watertight but also airtight. Concrete has the breathing property. It takes water/moisture and breathes out water vapour. Hindrance of this breathing property of concrete develops pore pressure, which causes blisters in the felt.
 
After a few seasons the blisters multiply and eventually delaminate the felt from the concrete surface. Hindrance of breathing property of concrete makes the concrete weak. But on the asbestos sheets and zinc sheets in factory roofs, this bitumen felt is the only dependable system. Hence all factory roofs in India adopt this water proofing system.
 
Bitumen is very effective in of basements from outside. Bitumen primers have very successfully been used as damp-proof course in earlier days. This practice is slowly discontinued for whatever reasons now very few engineers now believe that this was in practice once. As consequence of this absent DPC we have a lot of cases of rising dampness, which we tend to attribute to wrong reasons such as the quality or salinity of sand etc. Bitumen still is the product of first choice where it is commonly recommended, in areas such as industrial roof waterproofing, basement waterproofing, and damp-proof course. More over bitumen is the most economical product available for   
    
Metallic sheet wrapping
Because of the non-existence of suitable expansion joint filling compounds before the discovery of poly-sulphides, a complex procedure used to be adopted to treat expansion joints, in concrete dams and such huge structures utilising thick copper sheets. An extension of this practice was to try thin foils of copper and aluminium for wrapping the concrete surfaces with nagging leakage problems.
 
Unavailability of common joining material for these metal foils and the concrete and mortar created weakness in the system at the joints. This discouraged the system in its infancy only. But there after the metal manufacturers have been trying to market this type of system with improved adhesives as and when the metal market slumped.
 
based treatment
consists of two liquid components one is called the base component and the other is called reactor or curing agent. Base is a polyol and the reactor is an isocyanide such as TDI or MDI. There are various grades of and so also there are numerous isocyanides. The combination of these two ingredients results in a formation liquid applied rigid membrane or a foam depending upon the selection.
 
In waterproofing, this rigid liquid membrane was tried with fibreglass reinforcing mats. The systems failed because coefficients of thermal expansion of concrete and rigid PU membrane being different lateral movement or creep occurred with the passage on one working climatic cycle. When exposed to ultra violet rays or direct sunlight most rigid membranes became brittle and crumbled.
 
Apart from this the application of coating needed very rigorous surface preparation. The surface needed to be neutralised by removing alkalinity from the concrete surface through acid itching then washing and blowtorching to make the surface bone dry. This kind of surface preparation with acids angered the civil engineering community and the product ceased to be used as material apart from its several failures. Never the less continuous research in the technology gave the construction industry excellent sealant for glazing industry and foams for thermal insulations. The new generation polyurethanes, which are alkali stable and water-based, may find better applications in industry.
 
based system
Like is also a two-component system having a base resin and a reactor or curing agent. Base resin is obtained by dissolving bis-phenol A flakes in epichlorohydrin. This base is available in various viscosity ranges to suit different application conditions. The curing agent is an amine/polyamine aliphatic or aromatic, or an amine-adduct for general applications and polyamide or an amino-amide for coating purposes. After mixing base and reactor components the resultant viscous liquid or paste if some fillers are added to it can be brush applied like a paint or trowel applied like a mortar.
 
Here also epoxies not withstanding the alkalinity of concrete and the concrete needs to be acid washed and neutralised, which the civil engineers hated. Here again the coefficient of thermal expansion of concrete and being different the compatibility of in exposed concrete surfaces such as roofs became limited. Later the use of in was discarded. But epoxies have come to stay in civil engineering industry as bonding agents, floor & wall coatings, coatings for food processing units, operation theatres and computer and pharmaceutical industries.
 
Box type waterproofing
This type of water proofing system is used only for basement or structures below the ground level from outside to prevent leakages of subsoil water into the basement.
 
In this method, limestone slabs (Shahabad Stones) are first laid in the excavated pit over blinding concrete in a staggered joint fashion to avoid the continuity of the mortar joints. The joints are effectively filled with rich mortar admixed with integral compound and cured. Over this the raft is laid and shear/brick walls constructed. The limestone slabs are erected around the walls in a similar fashion leaving a gap of one to two inches between the external surface of the wall and the inner face of the stone surface. The joints again effectively sealed with rich admixed mortar and the same mortar is filled in the gap between the wall and the stones. This stonework is continued up to ground level. In this system the raft and the sidewalls are protected from direct exposure to sub soil water.
 
This system works on two principles of common sense. First, the area exposed to subsoil water is only the area of the joint where as the whole stone is impervious to water, hence only a fraction of area, that is, that of the joint is exposed to subsoil water, when the joint itself is filled with rich and quality mortar. Second, the path of water to reach the raft or the sidewall is elongated. This elongated path is through quality mortar. This system seeks to delay the occurrence of leakages in the basements. A lot of building structures are waterproofed by this system. A few notable successes are to its credit especially in five star hotels and of-course there are a few failures as well.

Rubix’s Cube roof puzzle solved with waterproof membrane

With a win in last year’s NFRC Roofing Awards, Sika Sarnafil Registered Contractor Contour Roofing has once again been recognised for its outstanding work, making the shortlist in the Single Ply category.

With the success of its previous award-winning project, Ewart Grove, a London residential new build, Contour was called on again by client Paul Simon Homes to offer a premium waterproofing solution for Cheltenham House. Another new build project in London, comprising of 11 luxury apartments, the entire roof and vertical works are shaped like a Rubik’s Cube.

Rubix’s Cube roof puzzle solved with waterproof membrane Cheltenham House 2 e1496328495319

Originally specified with metal cladding, the client wished to replicate this look for less cost, while achieving the same finish. Jonathan Woods, managing director at Contour, once more proved that Sarnafil’s single ply membranes can accommodate the most complex builds.

Contour worked closely with Sika Sarnafil to generate a bespoke specification with Sika Sarnafil’s self adhered membrane in lead grey, and décor profiles to emulate metal seams. Custom-made Sarnametal details were cut and fabricated to accommodate the various angle changes on the roof, including vent grills to the base of the cube.

Jonathan Woods explained: “Every single detail on this project has been carefully planned before application of the products.

“Sarnafil advised us to use the new Primer 610 and Self Adhered membrane and helped us to understand the product with demonstrations at its training academy and our offices. Change is always tough, certainly with experienced fitters, but we insisted that the Self Adhered membrane was paramount for the success of the roofing works at Cheltenham House. The product is quick and easy to use and leaves a beautiful finish to any application it’s used on.”

8 Easy Ways to Repair or Refurbish Your Asbestos Roof

8 Easy Ways to Repair or Refurbish Your Asbestos Roof

Repairing your leaking asbestos roof has never been more straightforward. Here's eight easy ways to fix your deteriorating bolts and washers, safely seal asbestos sheets and fix those leaky cracks in your roof.
1) Asbestos Crack Repair Tape

2) Asbestos Roof Hole Repair

3) Bolt Hole Repairs

4) Sealing General Roof Sheet Damage

5) Asbestos Single Sheet Replacement

6) Refurbish With a Specialist Coating

7) Over Cladding

8) Repairing Roof Lights

1) Using Crack Repair Tape

Where cracks are obvious, crack repair tape is a fast way to stop leaks in asbestos cement roofing – but not all tapes are the same. Although it’s tempting to resort to commonplace products, many are bitumen based, meaning they're affected by UV light and can easily crack in the cold.

Our solution is a rubber-based tape. It's UV stable, maintains its flexibility, and never sets hard – essential on roofs with cracks, where repair materials require the same high degree of movement as the roof itself. This cost-effective solution is highly effective and straightforward, making it first on our list, and an essential tool in any asbestos crack repair. You can get everything you need to seal that crack with our easy to apply repair kit.

Need a simple and reliable repair solution? We also recommend using the fibre reinforced instant repair StopGap.

2) Asbestos Roof Hole Repair

In emergencies, you need a product that works quickly. Again, we’d urge caution with some of the well-known products that claim to work in water and cold. To some extent they do, but when the integrity and weatherproofing of your premises is at stake, you really need a longer-lasting solution. We’re sure you would prefer not to keep sending someone back onto your roof to ‘repair the repair’. That's why we've created the DIY Asbestos Roof Hole Repair Kit, with everything you need and a step by step photo guide that makes it easy.

3) Bolt-hole Repairs

Bolt holes in your asbestos roof will eventually enlarge and the washer will corrode due to exposure to UV, making it ineffective. You can repair this by replacing the washer and bolt, or using a flexible tape or coating to seal the area. Where replacing the washer and bolt isn’t an option due to difficult access to the roof, the flexibility of crack repair tape is ideal. You can also apply an emergency repair coating to seal the bolt hole.

4) Sealing general roof sheet damage + cracks

Asbestos sheets will eventually deteriorate and that can mean leaks and water damage. This can lead to cracks. Nobody wants to watch their building and possessions being destroyed every rainfall. Many sealants don't have the durability for long term repair, particularly as frequent temperature changes cause the building to move. So even after repair, many building owners end up back on the roof.

That's why we only use UV stable, flexible, and highly durable repair solutions that can stand the test of time. You get a watertight repair that can stop your leak and seal your roof against the worst of the rain.

5) Asbestos Single Sheet Replacement

The traditional way is to remove the old sheet and replace with a new one. You can also use glass-reinforced plastic (fibreglass) GRP Oversheet, applied externally. GRP gives a guaranteed replacement lasting up to 50 years without deteriorating. It’s also completely waterproof, so you avoid the ongoing expense of treating it. GRP comes in various colours, and because it’s cold applied, you avoid the Health & Safety risks of heat treatment.

Find asbestos removal in your area

6) Refurbish with a specialist Coating

Coatings provide a permanent and highly effective waterproofing solution in an easy two step process. All loose asbestos fibres and lichen are encapsulated and bound with a Primer. Then a coating topcoat gives long-lasting protection and a completely weatherproof, UV and dirt-resistant roof that’s guaranteed to last for many years. When combined, the two components also encapsulate asbestos fibres and reduce the risk of their release, a comforting thought for all those spending time under the roof.

We’re the UK distributor for a wide range of coatings, meeting the demand for your every budget, desired longevity, climactic restriction and many other factors. We're all about choice, and our experts can provide everything from emergency patch repair to a long-term waterproofing solutions.

7) Over Cladding

When repairing asbestos cement roof damage with sealants or localised repairs isn’t possible, you could consider overcladding, by putting another roof (normally metal) on top of the old roof. This is a proven technique for repairing asbestos roofs and the next best method after coating. In most circumstances you’ll need to comply with current building regulations and add insulation to help reduce heating costs.

8) Repairing Roof Lights

Roof lights will eventually deteriorate, crack, leak, build up mildew and turn dark, so less natural light gets in. Repairing with tape is possible, but not ideal, and will restrict light further. Replacing the roof light is preferred, but working on roof lights is risky, especially if they’re in asbestos roofs.

There’s another solution, involving cleaning and coating the skylights with a tough, clear coating. This will improve the light tremendously and is far cheaper than new skylights. It’s also much less disruptive to your business and avoids having holes in your roof during the work.

Stop your roof lights from leaking with the liquid rubber SuperArmour.

We believe in good honest choices, and providing customers with independent advice about the options open to them. We've helped countless industrial building owners find a solution tailored to their needs, from emergency patch repair to full roof refurbishment, as well as catering for asbestos gutters and internal fibre encapsulation.

ROOFING COMPANIES FINED FOR WORKER’S FALL

ROOFING COMPANIES FINED FOR WORKER’S FALL

Two East Midlands roofing companies have been fined after a member of staff fell through a skylight.

The man suffered life-changing injuries from the nine-metre fall in December 2015 and required surgery to install metal rods in his back.

Coventry Magistrates Court heard how ACG Roofing Ltd had been subcontracted by JDB Industrial Roofing Ltd to complete re-cladding work on the fragile roof. At the time of the incident, no guard rails were being used.

A Health and Safety Executive (HSE) investigation found that principal contractor JDB Industrial Roofing failed to have effective management systems in place to control the risk associated with working at height and on fragile roofing.

The business, of Brooklands Court, Kettering, pleaded guilty of breaching the Construction (Design and Management) Regulations 2015, has been fined £112,000 and ordered to pay costs of £2,216.

ACG Roofing Ltd of High Street, Wellingborough, also pleaded guilty of breaching the Work at Height Regulations 2005. It was fined £35,000 and ordered to pay costs of £1,721.

HSE inspector Edward Fryer said: "This incident could have been fatal; the worker has suffered life changing injuries due to the company failing to properly plan and supervise work at height.

"This case highlights the importance of proper planning, supervision and implementation of work at height especially on fragile roofing."

Severn Trent Water customers encouraged to report water leaks

Severn Trent Water customers encouraged to report water leaks

SEVERN Trent Water (STW) customers are being encouraged to report water leaks which can develop in the winter.

STW has a network of pipes that would stretch around the world, and so customers often spot the leaks before the firm.

Malcolm Whittaker, from STW who has been finding and fixing leaks in the region for more than 30 years, said: "We take leakage very seriously, fixing on average 121 leaks per day and we want to bring leakage levels down as much as possible so that water isn’t wasted.

"This is particularly important when it’s cold as leaks can turn to ice and become very dangerous to the public.

"Engineers like me work day and night finding and fixing leaks and bursts, however we recognise that there may be some leaks that are still out there that we don’t know about.

“So we need our customers help.

"In many cases, we don’t know where leaks are until our customers report them. Please don’t assume we already know about the burst or leak, even if it is a large one: particularly in rural areas where it’s possible for leaks to run for days without being noticed."

Leaks or bursts are repaired on a priority basis, with those affecting customers’ water supply being fixed first.

Customers can check whether leaks have already been reported by visiting the STW website, and click on the check my area map section.

If a leak hasn't been reported call the STW's leakline number, free on most landlines. on 0800 783 4444 you can also report it here in your area on their website https://www.stwater.co.uk/in-my-area/report-a-problem/ or feel free to contact us.

Tips on preparing your roof for winter

Tips on preparing your roof for winter

INSPECT THE ROOF

Some people love the sound of rain, but nobody likes the drip, drip, drip of a leaky roof. So start your fall home inspection from the top, taking a good look at the condition of your roof. Curled, damaged, loose or missing shingles are signs that your roof may be compromised.

"Problems can arise anywhere on the roof, but more often than not, the best areas to check are generally where shingles meet any wall, chimney, skylight, pipe or other flashings," said Jeff Durocher, of Jeff Durocher Roofing in Little Falls.

A loose shingle doesn’t seem like much cause for concern, but it can lead to bigger problems. As Durocher noted, "if it blows off, becomes damaged in a storm or if there is a few feet of snow on the roof, the result can be a serious leak.Sometimes problems won’t be seen until expensive interior damage is already done. This makes what would have typically been a simple maintenance repair job much more invasive, requiring tearing up an area of roofing and removing and replacing rotted wood from scratch."

Before climbing a ladder to check out the conditions on the roof yourself, however, consider that a thorough inspection should really be left to a pro. "Some people may be tempted, but if your shingles are sliding out of place in one area, who is to say others won’t slide out from under your feet when you’re attempting a repair," cautioned Durocher. "Plus sometimes what looks like a small problem, can really be much worse. A professional may notice things that a homeowner cannot."

Although he doesn’t recommend leaving a roof inspection to a do-it-yourselfer, Durocher said you can also check inside your home for telltale signs of trouble. He recommends examining the ceiling for stains. Water stains usually have a dark ring around them and get larger and darker after it rains. Take particular note of what Durocher called "flashing regions," the walls and ceiling around skylights or chimneys.

DODGE THE DRAFT

Here’s one way to keep your heating bills low: seal leaks due to cracks around your home’s windows and doors. Weather stripping is an inexpensive solution, but it can deter-iorate, so check it and replace it if necessary.

Caulk is another easy remedy for drafty gaps not only around doors and windows, but for places on an exterior wall where cable, phone, electrical or gas lines enter the house. If there is existing caulk, make sure it isn’t cracked or damaged. If it is, scrape off the old stuff and re-caulk.

Test for drafts in all of these areas on a windy day now, and take appropriate measures before the temperature drops to freezing.

CHECK STAIRS, WALKWAYS, DRIVEWAYS

Chipped stairs and loose railings spell potential disaster, as do damaged walkways and driveways. And the danger is exacerbated when conditions outdoors are slippery and icy. Minor repairs to concrete surfaces are easy, however.

Clean out the crack thoroughly, using a wire brush. Then apply a concrete repair caulk or crack filler, which you can find in any home improvement or hardware store. You can also find patch kits for driveways, working the same way. But leave major repairs to large cracks, stairs and other concrete surfaces to a professional.

Finally, a few last words to the wise from Durocher, "A homeowner should look at their property before the bad winter weather comes and always look as often as possible. There may be problems a professional contractor can correct with simple standard maintenance. Being proactive with your property will go a long way in making sure your home is prepared for the most crucial months of the year."

CLEAN THE GUTTERS

Right now falling leaves, twigs and other wind-blown debris are not just covering your lawn, they are clogging your gutters and drain spouts. Cleaning the gutters is a minor task but it’s of major importance.

Said Tom Stachelrodt of North Jersey Gutter Topper in Ridgewood, "Clogged gutters in the winter prevent rain and melting snow from flowing away from your house, causing snow and ice buildup on your roof and gutters. This extra weight can result in gutters that pull away from or fall off the house. It also causes ice damming, which is a buildup of melting snow and ice that can [leak into] your home."

Clean, unobstructed gutters, on the other hand, head off potential water damage to the roof and also to siding and even your home’s foundation.

Cleaning the gutters yourself is relatively easy. You’ll need a trowel, or work gloves, to scoop out twigs, leaves, dirt or any other bits of things — including insects and other critters that may be nesting in there.

You’ll also need a sturdy ladder. Never stand on the roof and lean over to do the job. That’s dangerous.

Once you’ve cleaned out everything, flush the gutters with water, using a garden hose. Then make sure the downspouts are clear and nothing is lodging inside them.

However, Stachelrodt cautioned, "Cleaning your gutters once or twice a year does not guarantee clean gutters. You should clean them at least six times a year to ensure the flow of water away from the house."

You might consider installing gutter screens or gutter guards. A gutter guard is a product made of aluminum or super-fine mesh screening or perforated metal that goes over the existing gutter or it can be a heavy-duty brush that sits inside the gutter to prevent clogs [resulting] from the buildup of leaves and other debris.
