Frequently Asked Questions

When should I contact a waterproofing contractor?

The most evident call for a waterproofing specialist should be when you observe moisture, water droplets, or seepage on the walls or roof of the room. However, not every damage is an issue of leakage as many times the problem persists due to water pipe breakage inside. But you can consult with an expert to instantly diagnose the problem.

What is the life of waterproofing in Singapore?

Waterproofing on any surface cannot stay forever. But a solution provided by an expert waterproofing contractor can last up to 6 – 7 years. A major cause of deterioration of the waterproof coating is the weather condition in Singapore. A hot temperate climate creates contraction and expansion on the surface, which creates cracks over time.

What is the average pricing of waterproofing in Singapore?

Waterproofing is a bit costly affair as it involves minute analysis and repairing many unidentified damages or grooves. It depends specifically on the troubled area and the waterproofing contractor to charge. An average price is between $15 – $24 per sqm or $3 – $6 per sqft.

How much time does waterproofing a rooftop take to finish?

It depends on the damage repair work involved before coating. Usually, the contractors apply two layers of waterproofing for extra protection, and each layer requires 24 hours for drying. Thus, the quality work takes a bit more time, which is about 3 – 4 days.

How to Select the Best Waterproofing Contractor in Singapore? 

Waterproofing is a multi-step process that requires strong skills to diagnose the problem and provide an accurate solution. It is hard to test most of the problems instantly. Thus, a slight error in the analysis may ruin the efforts.
