Terrace Leakage & Waterproofing FAQs

Can a waterproofing coating fix poor roof slope?

A coating cannot correct standing-water problems caused by inadequate slope or blocked drainage. These issues should be addressed as part of the repair plan.

Should old waterproofing be removed?

Loose or incompatible layers should not be coated over blindly. Assess adhesion and compatibility before deciding whether to remove, repair or overcoat.

How do I estimate material?

Measure the area, add upstands and details, then apply the validated coverage rate and number of coats from the product data sheet.
