Waterproofing Around Two Balcony Drain Outlets

1. Where we started

The material around the drainsFloor drainThe outlet in a floor where water drains away on roofs, balconies and in bathrooms, with a grate on top and usually a trap below. had crackedCrackA split or gap in render, concrete, a wall, a coating or wood. Fine cracks are usually only on the surface; ones that grow, keep reopening or run diagonally need attention.. These are among the most sensitive spots, because all the water collects there.

2. Breaking out

Anything that isn't holding is broken out and removed, and the drains are sealed around their edges.

3. A waterproof patch

A white waterproof patch covers the whole area around the drains.

4. Beyond the damage

The patch extends beyond the damage so it also grips the sound surface around it.

5. The result

A final coat matching the floor covers the patch. The drains stay open and water runs away without finding any cracks.
