As roofs and terraces are mostly exposed to the changes in weather, they are commonly more prone to damages, which then leads to water leakages inside the building. Ensuring that proper roof waterproofing is done will prevent water seepages that may enter several parts of your area. In such cases, you may also find damp patches on your ceiling, suggesting a potential water leakage.

Significance of Waterproofing

Any structure or building requires waterproofing works as the concrete is unlikely to be water-resistant on its own. Most flats nowadays are basically constructed using reinforced cement concrete, a material that supposedly eradicates all the problems typically experienced by a flat roof. However, such material still needs to be waterproofed. As such, only engage in the waterproofing Singapore services of a trusted waterproofing company to ensure that your roofs will be free from any leakages.

Usual Practice

The R.C.C. slab of the terrace is constructed using ordinary concrete, that is, no admixture of any kind is utilised for enhanced workability that is needed for proper placement and compaction of the concrete through congested reinforcement. While there are times when certain waterproofing compounds are mixed in the concrete, they are not sufficient enough to prevent water leaks.

There is also a lime terracing done on the R.C.C. slab. The first purpose is to insulate heat, while the second one is to waterproof the terrace. On the other hand, this layer also exists to provide a slope that serves as a water drainage during rainy seasons.

More on Waterproofing

There are several waterproofing methods that you can use to waterproof your roof.

Before you undergo roof waterproofing Singapore services, make sure that you thoroughly consider the factors below:

  • Environmental conditions: a structure is generally subject to contraction/expansion caused by changes in temperature and weather conditions.
  • If the whole structure is weak due to sub-soil being very weak, poor construction, and vibrations from the surrounding pattern of land use, then the roof is highly likely to be adversely affected.
