Prestec have been involved in this large commercial basement renovation in London, SW1 since October 2016. This project involved installing over 500m2 of Delta Cavity Drainage Membrane to the basement level walls and pavement vaults and two Delta ground water sump and pump units including a fully maintainable perimeter channel drainage system.

Aside from the basement works, Prestec also waterproofed external areas of the building around the newly installed pavement lights and power cable pits using Koster 21. Due to the historic water ingress, Prestec have also completed several concrete repairs to the structure prior to the installation of the final finishes.

Prestec are currently completing the final stages of the internal finishes, such as sand and cement rendering, plaster boarding and all plaster finishes.

This project is due to be completed during February 2017.
