Case Studies | 200 sqm, Badly Failing Felt Roof in Jersey

This 200m2 roof in Jersey was in a bit of a mess. It had failed in several places and replacing it was going to be a massive undertaking.


That’s where the Hyperdesmo liquid roofing system came in. It offered a much quicker, and more cost-effective way, of restoring the waterproofing on this roof without the need to remove and dispose of the old felt. That said, it was in a pretty bad way which meant it needed to have a sacrificial liquid coat applied to even out the surface. This meant essentially flooding the deck with Hyperdesmo PB-1k FC, our 1 component, fast curing, bitumen enhanced liquid. This gave a much tidier surface for the waterproofing liquid to go on to.


Next was our BBA certified Hyperdesmo + Accelerator 3000A system. As the PB-1k FC cured to give a good surface, applying Hyperdesmo was a relatively straight forward job. As you can see, at the end, the roof looked much better and was waterproof once more.
