Built with concrete block and concrete infill, the walls had to be built in stages to avoid collapse from the weight of the concrete.

This created multiple “day joints” in the concrete and continuity would be affected. To overcome this, an expandable water-stop was laid at the wall/floor junction, and every layer of concrete was coated with a hydrophilic slurry that would seal the day joints.

Project Details

A new build house with a basement required waterproofing in Broughton Astley in Leicestershire.

Beautiful Basements was called in to design and install the waterproofing system. The main contractor built the slab and external skin of blockwork and erected the reinforcing steel. Beautiful basements then treated the wall floor junction with a hydrophilic slurry and an expanding rubber water stop to seal the most vulnerable point.

The main contractor then began building the inside face, laying three courses at a time and filling with concrete. At the end of each stage, a Beautiful Basements team went in to apply the slurry to the concrete before the nest pour.

When the walls have been finished, we returned for a final time to install the cavity drainage membrane to the walls and floor and the fit the two pumps in the sump.
