Brick Bat Coba Waterproofing, Is it Good ??

Traditional terrace waterproofing methods in India include brick bat coba, tarfelt and bituminous treatment. However, these methods have their own limitations and are now being replaced by advanced and innovative solutions such as roof waterproofing paints, primers and sealants.

For instance, the brick bat coba system is one of the most common flat roof waterproofing methods and mainly involves placing brick bats on roofs to make a slope that facilitates smooth water drainage. However, this system cannot be called an effective waterproofing method because of the following limitations:

• It causes unnecessary load on the terrace slabs which can be impossible to repair when cracked.
• This method is vulnerable to temperature variations which again can lead to the development of cracks.
• Bricks used in the method are porous and can hold a large amount of water, leading to water stagnation and leakages.
• The manpower and expertise required for the application of conventional methods is not present these days causing the system to fail.
• Removing the brick bat and coba from the terrace requires a lot of effort and is often time consuming. In some cases, the material is even fixed to the main surface, thus causing surface damage while dismantling it.
