Banwet : Waterproofing the roof is an effective measure to prevent leakage. This can be done in two ways. One is waterproofing during home construction as a precaution against leakage. This is called Integral Waterproofing. The second is waterproofing on the roof (external waterproofing) to prevent leakage.
before plaster after the roof . It is made from bitumen, polymer, latex and acrylic.Bitumen based waterproofing products are available in the form of brush roofs and adhesive sheets on the terrace. The paste-shaped mixture should be rubbed at least one mm thick. It can be plastered over three to 48 hours. Square Feet costs around 25-30 rupees including labor. If you do not plaster the top, it will break down after a while.
Waterproofing can be done using bitumen sheets that are 10 meters long and one meter wide. The sheet is available in thickness of 3mm to 6mm. They are spread out on the terrace and then rolled and pasted on the edges. Square Feet costs around Rs. It is better to do some thin plastering over this. The reason is that these conditions are likely to be mild in the state of Kerala which is experiencing heavy rainfall and extreme heat.
The feature of the acrylic based waterproofing material is that it lasts longer. This type of coating is done in three installments after the primer has been struck on the roof. The coating shall have a mm thickness. The advantage of acrylic coating is that it does not break down under heavy heat, and does not get stirred by regular rain.

How do you temporarily stop a roof leak?
Large PVC pipes for drainage of rainwater into the roof and sunshade are common along the walls. Flat-roofed terrace houses are most likely to be flooded with water. Over time, the risk of leakage increases. It is only when a puddle of steam is poured over a concrete fence, that it will rain like a pitcher. When ripe concrete is suddenly cooled, there are small cracks. Again, when it rains and the water recedes, the cracks will burst and the water will begin to leak. Solar water will flow through the area where the defects in the concrete are, and the worst part of the concrete and plastering inside the house will be spilled. Falling tiles on the terrace can cause water to leak through the cracks.
If the parapet is tilted instead of flat, the water will flow. If it is flat, you should apply exterior emulsion paint that is well scrubbed and does not hold mold and mold. Falling tiles on sloping sunshades can help prevent leakage. Due to the lack of sand, the quality of the rock powder and the variations in the shape of the rock currently used can lead to problems with the concrete.Using quality cement can also solve problems.
It is better to avoid building by adding water, cement, sand and quantity. It is common to retain parts of an old house and add new roofs. If the mixing is not good, there is no doubt that the water is soaked through this part.These types of houses can be found in many places. Adding polyurethane or polysulfide sealant to additives is beneficial.
