Waterproofing is essential to protect your home from diverse climates, especially during monsoons, when heavy rains can wreak havoc on poorly protected structures. With moisture seeping into walls, ceilings, and floors, the risks range from structural damage to unhealthy mould growth.
Thankfully, modern waterproofing solutions can protect every surface of your home, ensuring durability and comfort. Here’s a complete guide for Indian homeowners on waterproofing your house, one surface at a time.
1. Roof Waterproofing
Intense heat and monsoon rains make roofs highly vulnerable to leaks and cracks. For a durable, water-resistant barrier, use a waterproofing membrane, such as a liquid-applied or sheet-based option. Bitumen coatings are affordable and highly effective for flat roofs. They seal cracks and prevent water ingress.
Waterproof coatings with reflective properties also reduce heat absorption, keeping your home cooler in summer. Ensure proper drainage and regular maintenance to prevent water accumulation on your roof.
2. Wall Waterproofing
Indian homes often face problems like paint peeling and damp patches on walls due to water seepage. The solution lies in external and internal wall waterproofing. Use weather-resistant coatings like silicone-based or elastomeric paint to protect against rain and UV damage.
For interiors, apply a waterproof putty before painting to prevent dampness from seeping through. Repair all visible cracks with a sealant or crack filler to block water entry. Consider anti-fungal paints for areas prone to high humidity.
3. Bathroom and Kitchen Waterproofing
Bathrooms and kitchens, being wet areas, are highly prone to water seepage. Water can infiltrate into nearby rooms and erode the structure if the area is not properly waterproofed.
Apply a polymer-modified waterproof coating before laying tiles. Ensure proper slope toward the drains to avoid stagnant water. Use waterproof grout and seal it to prevent water seepage through tile joints.
For extra protection, coat walls with cement-based waterproof products before installing tiles. Check plumbing regularly for leaks. Constant pressure can cause even the greatest waterproofing measures to fail.
4. Basement Waterproofing
Basements in Indian homes are at high risk of water damage due to rising groundwater levels during the rainy season. To create a water-resistant barrier, apply waterproof coatings like epoxy resin to walls and floors.
Before construction, waterproofing membranes or bituminous sheets should be used on the exterior side of the basement walls. A proper drainage system should also be installed to redirect water from the basement.
5. Terrace Waterproofing
The terrace is another area that bears the brunt of Indian weather extremes. Without proper waterproofing, water can seep through and damage ceilings below.
Apply a liquid membrane evenly across the terrace to create a seamless water barrier. These are economical, durable, and UV-resistant, perfect for terraces exposed to harsh sunlight.
Brickbat coba is a traditional waterproofing method in which a layer of cement and broken bricks is laid to prevent water retention.
6. Window and Door Sealing
If not sealed properly, windows and doors are common entry points for rainwater. Use silicone sealants or weatherproof strips to fill gaps between the window/door frames and walls.
Install window awnings or rain guards for added protection. Regularly inspect wooden frames for warping and apply varnish or waterproof paint to protect them from moisture.
7. Water Tank Waterproofing
Underground and overhead water tanks often develop leaks over time, wasting water and dampening surrounding areas. Coat the inner and outer surfaces of water tanks with a cementitious waterproofing product.
Repair visible cracks immediately with epoxy-based sealants. For older tanks, consider a complete re-lining with a waterproofing material.
Conclusion
Investing in waterproofing increases the longevity and safety of your house. Whether it’s your roof, walls, or basement, each surface has its unique requirements. Modern waterproofing solutions tailored to Indian climates make protecting your home from moisture damage easier than ever.
