Help nature recover


The concept of building the structure into the hillside was a journey of discovery for the whole team and their unique approach to the project was perfectly executed against a very challenging timetable and sequence with other trades. The final results speak for themselves.

Pre-fabricating membranes also eliminates the risk that traditional jointed systems pose. This is especially important for green roofs where it removes the need for a root barrier.

For jobs of greater complexity, for instance those involving lots of detailing or without the protection of a green roof layer on top, our waterproofing partners will sometimes use Resitrix, a glass-reinforced and bitumen-backed EPDM system available exclusively ‘off the roll’ or, more frequently, a liquid-applied system that covers complex details like a GRP with fewer of the toxic ingredients.
