This stunning new-build with floor-to-ceiling glass panels is built into the North London hillside and thus required a robust waterproofing solution from Newton for failsafe protection.

Built into the hillside, the property was therefore partially-retaining and required a full waterproofing system throughout to protect from unwanted water ingress. As such, Newton Specialist Contractor Stonehouse were called in to expertly install a robust waterproofing system to the entire structure.

The client appointed Stonehouse's Richard Allen as the waterproofing design specialist on this project, to ensure a fully BS 8102:2009 compliant build.

Due to the partially-retaining nature of the structure, Richard recommended a combination of Type A, B and C waterproofing systems to ensure a Grade 3 habitable environment.

Relying on an effective Type B structure, Stonehouse then applied a cementitious coating of Type A Newton 107F to the external surface of the flat roof decks and to the internal area of the lower lift pit.

Given the high risk from water, the Newton CDM System was also installed on both levels of the structure. Newton 508 membrane was securely fixed to the internal walls using Newton's ancillary products, with water from the upper level being bunded and piped down to the lower level, then drained via gravity fall using Newton Basedrain.

Stonehouse were able to provide a 10-year guarantee for the installation.

"This was a challenging project from the start due to the complex construction of the building with different levels and a high risk of water ingress through construction joints, fully retaining elevations and external podium decks. We had to combine a wide range of Newton's products in our design and installation to achieve a continual barrier and satisfy the requirements of both the client and main contractor whilst achieving a system that is in full compliance with BS 8102:2009." - Richard Allen CSRT CSSW, Senior Surveyor, Stonehouse
