Cavity drain membrane system specifed to waterproof a basement

An iconic fire brigade building at Birmingham’s Lancaster Circus has been converted into halls of residence, with the ability to accommodate over 450 of Aston University’s students.

To make it fit for its new purpose, the building had to be waterproofed.

Moisture had a tendency to penetrate through the wall/floor joint and enter the building’s basement via cracks in the flooring.

Triton’s Platon P8 cavity drain membrane was specified as a waterproofing solution.

Waterproofing with cavity drain membranes

3,000 square metres of Triton’s membrane have been used to create a Type C drained waterproofing system for the area.

As a cavity drain membrane, the Platon system allows water ingress to enter the building through the walls; however, it then controls it and diverts it down the wall to a perimeter drainage conduit.

The conduit then redirects the water to one of 10 sumps.

Each sump accommodates one of Triton’s Aqua Pump Pro Plus kit, which comprises mains powered and battery back-up pumps.

Reducing hydrostatic pressure

Despite the original problems, many of the building’s floors have been kept in place.

As the Platon system allows moisture to enter its structure, there is no hydrostatic pressure on the existing floor slabs.

Because of this, there is no need to replace them.
