Choosing a waterproofing specialist
Seepage and leaks damage plaster, paint, false ceilings, flooring and furniture, and they get worse every monsoon. Good waterproofing starts with finding exactly where the water comes from.
Common problems
- Roof leaks: cracks, blocked drains, ponding water and weak roof-parapet joints
- Rising damp: damp bands at the bottom of walls, often from a failed damp proof course
- Bathroom leaks: failed grout, joints and concealed pipes
- External walls: rain entering through cracks
- Water tanks: underground and overhead tank leaks
Common methods
Cementitious coatings, liquid membranes, bitumen membranes, injection damp proofing and heat-reflective roof coatings. A good specialist inspects first and explains why a method suits your building.
Timing
Roof work needs dry weather, so book inspections in the dry months before the monsoon.
Questions to ask
- Where is the water coming from, and how did you confirm it?
- Which product, how many coats and what thickness?
- Does the price include surface preparation and crack repair?
- What written warranty do you give?
Questions about waterproofing & chemicals
Will repainting stop seepage?
No. Paint cannot stop water coming from behind. The source has to be fixed first.
When is the best time for roof waterproofing?
In dry weather before the monsoon, so surfaces are dry and the coating can cure properly.
Can heat-reflective coatings make rooms cooler?
Light-coloured reflective roof coatings reduce heat absorbed by the roof, which top-floor rooms notice in summer.
How do I know if a pipe is leaking inside the wall?
A damp patch that stays wet in dry weather, or a water meter that moves with all taps closed, are common signs. A plumber can pressure-test the lines.
