Products | Roofs | Exposed | Concrete Substrate | Crazed or Weak

Waterproofing a concrete roof can be a challenge. Concrete tends to expand in hot weather and contract when it’s colder which, over time, can cause it to crack. This presents a challenge to most concrete roof waterproofing solutions. Any such systems needs to be:

  • flexible enough to expand and contract with the concrete
  • strong enough to be able to bridge over any cracks that develop in the concrete
  • strong enough to not split or crack whilst doing so.

The BBA certified Hyperdesmo system does just that! It has great flexibility to cope with expansion and contraction, even on very large roofs. A fully reinforced system will limit the movement in the substrate during expansion and contraction phases, thus resulting in a longer lasting system.

Below are a selection of the primers, sealant and ancillary items including the Hyperdesmo liquid itself. Also you will find Hyperdesmo ADY-E, our protective topcoat system which protect the membrane for years to come.
