Luxury New Hillside Home, North London
November 2019

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

The Project

After the original property on this site in Barnet was demolished, construction began for a new building that could take full advantage of the stunning location. With floor-to-ceiling glass panels on one side of the property, this new-build is the best place to admire the views over London.

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 Solution

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 failsafe 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.

The Result

As one of our most experienced specialist contractors, Stonehouse expertly recommended, designed and installed a truly failsafe waterproofing system that will continue to protect this contemporary home for many years to come. Furthermore, Stonehouse were able to provide a 10-year guarantee for the installation, for complete peace of mind.

"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.
