The Damptec team has begun work on a new build lift pit in Manchester. We recommended a combined waterproofing system:
- Type A (barrier protection), external waterproofing, walls and floor
- Type B: (structurally integral), designed and installed by a third party using waterproofed concrete
Preparation by Damptec Systems Ltd
- The slab was jet washed to create a clear and clean surface.
- The existing rebar was cut off to ground level (see photo 1)
- We then applied Koster Repair Mortar over any holes
- Over this we applied 2 coats of NB1 Grey (see photo 2)
Waterproofing specification proposal:
- First visit: Install Delta Amphibia pre-applied waterproofing membrane to the prepared lift pit slab prior to the installation of a secondary cast slab. The secondary slab will be deep enough to accept the lift fixings.
- Second visit: Install Koster Quellband (water bars) at the construction joints, followed by the Installation of Delta Amphibia pinned to the OSB timber formwork walls
Main Contractor:
To cast r/c concrete structure to include external walls in sacrificial OSB formwork up to ground floor level.
