What we did

We installed waterproofing with protective heat insulation on the basement, garret floor, elevator shaft, excavations for water supply, foundation piling and the basement slab shafts.

What we used

For the elevator shaft, excavations for water supply, foundation piling and the basement slab shafts we used laminated membrane GRACE Preprufe 160R. We installed laminated membrane GRACE Bituthene 4000 with EPS 120 insulation plates on the basement walls. The open roof areas were waterproofed with the laminated membrane GRACE Bituthene 4000, the overcoating of the same extent of the laminated membrane GRACE I&WS. To stop water from penetrating between the structure and waterproofing, we sealed the laminated membrane edges with liquid membrane. To protect turns up we used the protection board Servipak 3 mm and the heat insulation onto the horisontal open roof.
