Roof Waterproofing Brickbat Coba Dr Fixit Roof Seal

Why Waterproof Roofs?
In any construction, the longevity of the building depends to a great extent on the waterproofing of the roof. One should bear in mind that the roof accounts for 30% of the structure's surface, so it pays to have it correctly waterproofed to keep the rest of the structure safe from damage due to water seepage. If a new roof is waterproofed correctly, it will increase the life of the structure, thus be a great convenience to the residents and also add to the reputation of the builder.

The issue of waterproofing of roof has to be dealt with care and one must ensure that the right products are being used in the right manner. Conventionally, the concrete roof slab is covered with Brickbat coba (BBC), Mud phuska, China mosaic, tiles or screed to provide a slope to drain rain water. While most believe that this waterproofs, with time, get cracks in top layer, allowing ingress of water into the roof slab. This leads to leakage and corrosion of the steel, thereby weakening the roof slab and causing dampness inside the house.

Waterproofing that lasts
To give longevity to your roof and ensure that the waterproofing lasts atleast twice as long as conventional methods, Dr Fixit has developed waterproof coatings which create an impervious barrier between the concrete slab and the layer above. Dr. Fixit Waterproof coatings being elastic in nature can withstand temperature variations and can bridge micro-cracks thus preventing ingress of water.

The advantages of these new roof waterproofing products are many, including faster application and less labour intensive. In fact, when it comes to ease of application, nothing can beat the spray applied waterproofing products like the Dr. Fixit Blueseal, which is 5 times faster application than that of brickbat coba and offers 3 times more life expectancy. Moreovers it is without joints, making it a strong and seamless barrier against water seepage.

Dr Fixit Roofseal is another excellent brush applied product that is recommended for new roofs. It should be directly applied on the concrete slab and it creates an impermeable layer under the conventional system like BBC, Mud phuska and China mosaic.
