MAYFAIR OFFICE

Diagnosis
This project involved us assessing an unused large vault below a busy office. It was ideally positioned as a meeting room but was wet and unaltered since first used for the storage of coal delivered through the coal hole in the pavement outside.

Solution
We lined the vault with a meshed cavity drain membrane system, draining into a sump and pump set into the concrete floor slab. We carefully lined shafts to glass block windows which replaced the original air vents and provide some natural light.
