Warwick Court Redevelopment, London

Mace Group’s redevelopment of Warwick Court in Paternoster Square, London, involved expanding the floor space to 300,000 sq ft. The project has two basement levels that were required to accommodate plant rooms, a car park and loading bay.

The Project

Warwick Court, the former Goldman Sach's headquarters on Paternoster Square in London, is being redeveloped by Mace Group after they won the project in 2020. The development involves expanding the floor space to 300,000 sq ft, following a plan drawn up by architect Fletcher Priest. As part of the large scale redevelopment project, two basement levels were required to accommodate a car park, loading bay, plant rooms and storage.

The Solution

Mace approached Newton and our specialist contractor ASF Waterproofing to specify a waterproof and hard-wearing coating system for the floor of the plant rooms. As a result, ASF Waterproofing designed and installed a watertight system utilising Newton 110 WATstop and Newton 701-HB.

Firstly, after the surface had been properly prepared, the fibre-reinforced cement/epoxy workable mortar 110 WATstop was applied as a waterproofing layer to the floor of the plant rooms, providing a smooth surface that also repairs the surface of concrete.

Secondly, the epoxy resin-based floor coating 701-HB, was applied afterwards to provide a hard-wearing coating to protect the waterproofing layer. ASF mixed in kiln-dried sand to the first coat for added grip, making the floor safer to walk on.

The Result

ASF Waterproofing provided a completely watertight solution following the guidelines set out in BS 8102:2009. The works were carried out to a high standard and delivered on time, despite the tight schedule.

Newton are proud to have been involved in this project, run by property developer Stanhope, who ran the development with an all-female senior team for the first time, setting a benchmark for the future of women in construction.
