“I’ve worked closely with CLW on the Salisbury Square Development scheme, and they have shown outstanding value in picking up on issues early, guiding the design team and ensuring work on site complies with the best practice.
Working with CLW has given me confidence in our development and the basement waterproofing. I would highly recommend engaging with them on any development with a basement.”
Jianxi Cheng, Director, Avison Young
The City of London Corporation identified a unique opportunity to create modern facilities for both the City of London Police and His Majesty’s Courts and Tribunals Service in the heart of the historic Square Mile.
CLW has been commissioned as the waterproofing design consultant for a large three storey basement, which extends over the entire site. This includes buried deck/podium elements, as the basement extends beyond the building line at ground level.
Working closely with the entire design team to provide a clear and efficient design for the Grade 3 waterproofing, specifying both Type B (structurally integral) and Type C (cavity drainage) protections to achieve this.
