Waterproofing a Below-Ground Listed Property, London

Summary

We were given the opportunity to aid in the waterproofing a below-ground listed property in London. Newton is proud to contribute to the transformation of the unique, listed property in Marylebone, as it undergoes major refurbishment. The residential property needed a complete revamp of the lower ground floor level, along with the external stabilising works to turn a damp, unused area into a habitable space.

The Project

A stunning property in Marylebone was undergoing major refurbishment. This 600sqm private residential property needed a complete revamp of the lower ground floor level, along with the external stabilising works to turn a damp, unused area into a habitable space. The area was to be used for climate-controlled wine storage, a steam room and sauna, and plant space. Main contractor OLF Construction recommended Newton Specialist Contractor MacLennan to the architect, Arkle Boyce, for the waterproofing works.

The Solution

After surveying the property, MacLennan concluded that the Lower Ground Floor was at risk of water ingress. The structure hadn’t historically had water ingress issues, however, when designing waterproofing systems you need to future-proof the building.

Various issues can bring water to bear against a structure in future, like blocked street drainage. If you do not waterproof the structure appropriately, it could sustain damage. In this case, we also needed to waterproof the main body of the house.

Given this was an existing structure, the best solution for protecting it was to use Newton’s CDM System for cavity drain waterproofing. The system has minimal impact to listed buildings, and includes drainage and sumps and pumps to remove any potential water ingress.

The Result

MacLennan installed waterproofing to the Listed building in Marylebone, ensuring that the client was able to optimise their available, existing space.

They transformed the unused space into a wine cellar, steam room, sauna, storage and plant area. Finally, MacLennan completed the work within the agreed time frames and budget, providing their installation guarantee and Professional Indemnity insurance for the design.

Another trouble free project using Newtons range of waterproofing systems and materials. We want reliability and quality and that is what we get with the Newton cavity drain and pump systems Ian MacLennan, Managing Director, MacLennan
