Most of the large-area concrete roofs after about 5-7 years appear many problems of leakage, displacement, cracking … especially with roofs with many components placed on the roof. But because the old waterproofing system of the concrete roof is often under the concrete layer, the renovation of this layer needs a lot of effort but not thorough. If you do not break through, but choose to apply an additional layer of liquid waterproofing on top of the concrete, it will not cover the cracks and the positions of the roof-piercing components.

Roofcare proposes the solution of using TPO membrane system directly on the concrete roof, covering the entire roof system like a separate garment, covering the cracks, seamlessly apply at the penetration while still ensuring watertight, effective waterproofing.

TPO membrane system with flexible structure can withstand the displacement of the concrete roof while maintaining the waterproofing effect.
