The project was a new build apartment development next to a school in Dollis Hill. As the basement underground car park, for the new residents, had a larger footprint than the building itself it meant there was a substantial podium deck to be waterproofed.
After various discussions with the client Capel were awarded the contract and the system chosen was the fast cure sprayed liquid DOW Hyperkote. Once the concrete slab was cleaned and prepared (some crack repair was required) the primer was applied. When large areas were ready a spray machine was brought in and the membrane itself sprayed. There was a 500mm upstand at the façade of the building and a 600mm downstand at the edge of the podium (ie down the wall).
Once the areas were sprayed a 6mm drainage board and geotextile sheet were laid over that before the landscaper laid the fill and paving/plants.
