Waterproofing for Flat & concrete roof
Flat & concrete roof waterproofing
Flat concrete roofs pond water and move with heat — so hairline cracks open and water tracks into the slab. The fix is a continuous, crack-bridging membrane laid to falls, with every upstand, drain and joint detailed.
The Fix
