It is important that a waterproofing contractor in Singapore traces rationally through the symptoms of a trouble and accurately recognizing the cause as opposed to taking the easy way out and treating the first thing he sees.
Why buildings leak frequently?
The wall surfaces of a lot of buildings these days have reinforced concrete upright columns with enhanced ring beams along the top that provide the durability. The spaces in between the columns and beams has an infill of light cinder blocks or soft local red bricks with a skim of tough concrete on the exterior. The enhanced concrete is often very inadequately made with splits and cavities in it and the infill resembles blotting paper (sorry you might not remember that, like a sponge).
Inspect the surfaces of the wall surface
When you have checked along the top of the wall next take a look at the surface area of the wall surface. Carefully check it from top to bottom. Is it open to the weather. Note that if you are in a gusty area the wind can push rainfall at high angles against the wall surface. Sensibly designed structures have good roof covering protrudes which are made to maintain rain off the walls. Roof overhangs also keep sunlight off wall surfaces and so keep within room temperature levels down.
If you have a wall left open to drizzle you can waterproof it to stop water entering. Take particular note of any fractures in the wall surface which will need special treatment, we’ll come to that in a minute.
A word of caution, a wall needs to breath to ensure that if water does get into it can evaporate out once more. Do not water-proof both inside and outside surfaces of a wall. If you do you might well always have moist walls.
Dealing with the leak
Alright so we have discovered the cause, how do we treat it? The standard method is to utilize a skim of elevated density waterproofing cement but this is not a method I recommend. This kind of waterproofing film is very breakable and can crack. On a surface exposed to sunlight the surplus surface area heat will fracture the concrete skim away from the wall surface under allowing water to go into which can travel in between the concrete skim and the surface under.
Waterproof Concrete Finish
It is a cement-like layer that can be used externally of wall surfaces without having to peel the paint. This kind of covering, which is essentially a waterproofing membrane with polymer adjusted concrete top, is a simple solution to all your seepage and dampness issues.
This type of waterproof finish is generally utilized for indoor walls, specifically in the washrooms. It is among the best ways to water-proof the basement wall surfaces.
