Our clients wished to convert their basement into a gym and instructed us to proceed with the structural waterproofing design and installation. We duly liaised with Architect Andrew Bellas who drew up the plans.
However during an early site visit we noticed that previous owners had excavated the soil from beneath the Victorian footings of this three storey property. We advised our client that this would need to be corrected and the foundations stabilised before any structural waterproofing works could begin. We contacted Chris Simms, Structural Engineer with Peak Engineers, who drew up the specification to stabilise the foundations. This involved the installation of a reinforced concrete floor slab and a substantial upstand around the base of the walls.
Once this remedial work had been completed the structural waterproofing element could begin incorporating a retro-fit Type C Cavity Drained System. The final stage involved installing the membrane on the walls at which point we contacted Quadrant, Approved Inspectors Building Control, to approve the works. Our client now has the extra space they needed in the knowledge that the work comes with an industry-recognised guarantee and has been carried out in line with BS8102 (2009) Code of Practice for the Protection of Below Ground Structures Against Water from the Ground.
