Tanking System To An Existing Basement
Our waterproofing expertise was called upon once more by a reputable building contractor who is undertaking the renovation of a Victorian property in Alderley Edge, Cheshire.
Following the removal of the existing basement floor – to maximise the finished floor to ceiling height, a new concrete base slab was introduced, incorporating the required chases to accommodate the necessary serviceable floor wall joint drainage channels.
Similarly, an excavation point was incorporated to accommodate the required sump chamber that will contain the primary pump, battery back up pump option and high water level alarm.
The waterproofing system chosen meets BS 8102 grade 3, which was accepted by the Architect and local Authority, and consists of high density polyethylene stud profile membranes, serviceable floor wall joint drainage channels terminating within a preformed sump chamber.
On this particular project the existing original solid staircase was to remain, this was not an issue as the stud profile membrane was installed over the staircase, sealed to the wall and floor membrane system, then overlaid with timber treads and risers, fixed into the original staircase using special water sealed fixings.
The contract is now complete from a waterproofing aspect and is currently being fitted out by the main contractor.
