Step by step
1. The planter before
The built-in planter on the terrace held soil and plants. Once the waterproofing underneath fails, water from watering seeps into the building.
2. Emptying it
The plants and soil come out so the base can be seen. The old black coating is visible on the walls.
3. A clean base
The floor is cleared of soil and loose material, so the new layer bonds to a sound surface.
4. First layer
A first grey layer goes on to prepare the surface for the waterproofing.
5. Into the corners
The layer runs right up to the foot of the walls, because leaks usually start at the corners.
6. White waterproofing
The white waterproofing covers the floor and goes up the walls, so the planter becomes a closed basin that keeps the water in.
