Project Details:

Dry Waterproofing Ltd were contacted by Mr Martyn Grant of PBA Structural Consulting Ltd to provide a solution for dealing with the flooding problem that was affecting the bathroom and utility room within the basement of this typical Victorian house.

The house had been converted into flats by the property owner, and as part of this conversion work the basement floor was lowered to obtain more headroom.

The walls were also underpinned and waterproofed (tanked) with a cementitious render during the process. They informed us that the flooding problem came about following repairs to a bust/leaking soil pipe that was concealed in the base of an earth retaining (tanked) wall.

This was caused by a blockage in the street sewer/pipe network. Gaining access to the concealed pipe compromised the existing waterproofing system and thereby allowed ground water to enter the structure.

Result:

A fast track sympathetic approach of dealing with an age old problem of waterproofing structures below ground was achieved quickly. This enabled the client’s builder to install fixtures and fitting to the independent dry lining system without fear of compromising the waterproofing and was much faster than traditional cementitious waterproof (tanking) systems.

Benefit:

The owner of the property needed to have the basement back in habitable use quickly so they could to let the flat to tenants as soon as possible. The installation of the Newton membrane system achieved this with benefit of a long term meaningful guarantees, which is insurance backed.
