Building your dream home is an exciting experience, but if you forget to add waterproofing during construction, it can cause expensive repairs and damage later. Water leaks in the walls or stains on the ceiling can happen if waterproofing is not done right. Good waterproofing helps keep your home strong, safe, and nice for many years.
Here are the important areas you need to waterproof when building a new house:
Terrace and Roof
The roof protects your home from rain and heat. If it is not properly sealed, cracks can appear, letting water into your ceilings and walls.
– Use special waterproof coatings, membranes, or sealants made for terraces.
Bathrooms and Wet Areas
Bathrooms often have water, and leaks can spread to nearby rooms or floors.
– Use waterproofing chemicals on the floor, wall seams, and around pipes before putting down tiles.
Basement or Foundation
Basements can easily get wet and flood. If they are not protected, this can lead to mold, damage to the building, and bad smells.
– Use waterproof materials and coatings to protect the foundation.
Water Tanks (Overhead & Underground)
Leaks from tanks waste water and can damage your building structure.
– Apply food-safe waterproof coatings inside tanks and seal external surfaces to prevent seepage.

External Walls
External walls face constant exposure to rain and humidity. Over time, this can cause cracks, peeling paint, and damp interiors.
– Use breathable waterproof paints or elastomeric coatings on outer walls.
Balconies and Sunshades
These smaller areas are often neglected but can cause major leakage issues if improperly waterproofed.
– Treat balcony floors and joints with flexible, UV-resistant waterproofing products.
Pick Reliable Waterproofing Brands
For lasting results, use good products from trusted brands like Dr. Fixit, Sika, Fosroc, MYK Arment, Mahafix, and more. Talk to a waterproofing expert during building to make sure you select the right solutions for each area.
