He surveyed the site three times personally to ensure that the scope of work is correctly defined so that there is no over quote. His Team was also very prompt in the delivery of the services.

Frequently Asked Questions

Waterproofing is the process of making a structure resistant to water penetration. It prevents leaks, mould, and long-term damage — protecting both the building and the people using it.

Common problem zones include:

  • Bathrooms and toilets
  • Balconies and planter boxes
  • Roofs (flat, pitched, or metal)
  • Kitchens and wet areas
  • Basement walls or retaining walls
  • RC gutters and slab joints

Some early warning signs:

  • Damp patches or peeling paint
  • Musty odours or mould spots
  • Watermarks or stains on ceilings and walls
  • Cracks in tiles or grout
  • Visible leakage after rain

It depends on the system used and exposure conditions. Most quality waterproofing lasts between 5 to 10 years, but proper installation and maintenance can extend that further.

The best time is before a problem starts — during construction or renovation. But if you’re already experiencing leaks, the next best time is as soon as possible to avoid deeper structural issues.

We recommend checking high-risk areas once every 1–2 years, especially before and after the rainy season. Early detection helps prevent bigger repairs.
