Waterproofing Luxury Houses, Yorkshire

Rural Holmfirth in West Yorkshire was the site of this luxury, 12-property housing development. Built into an embankment on a sloping site, and with each unit expected to retail at £400,000, it was crucial that they were waterproofed to a ‘Grade 3’ habitable standard.

The Project

With the lower ground floor of each new unit requiring earth-retaining elevations and a habitable internal space, a structural waterproofing specialist was required as an integral part of the design team.

Newton Specialist Contractor Protectahome were approached by the property developer to fulfil this role, and provide a guaranteed and cost effective scheme that would comply with the requirements of both BS 8102:2009 and any third-party warranty providers.

The Solution

Protectahome’s CSSW-qualified surveyor worked alongside the project designers and engineers in order to design a combined waterproofing solution, bringing together Type A (barrier) and Type C (drained) protection in order to create a Grade 3 (habitable) internal environment.

The Type A system was achieved with the Newton HydroBond System, utilising a Newton 109-LM seamless rubber waterproofing membrane externally to the blockwork structure, before protecting the membrane and the structure with Newton 410 GeoDrain drainage membrane, protection boards, free-draining backfill and a serviceable land drain.

With the structure complete, the internal waterproofing was achieved using the Newton CDM System, utilising a Newton 508 cavity drain membrane with Basedrain perimeter drainage to direct water to a safe passive drainage point, thanks to the sloping site.

The Result

The professional installation was completed both on time and within budget by Protectahome’s specialist operatives, and was also covered by a long-term guarantee for each property, issued by Protectahome.
