Safeguard Basement System 1
Where basements are excavated and backfilled in the traditional way the primary waterproofing system (Vandex Super) can be applied to the external face of the basement wall. This is covered with a subsurface drainage layer (Oldroyd Gtx) to reduce the hydrostatic pressure coming to bear on the basement structure and reducing the risk of water ingress through defects.
As a second line of defence, a maintainable cavity drainage system (Oldroyd Xv) is installed on the internal side of the basement walls.
- Combined protection (BS 8102 6.2.2).
- Maintainable internal cavity drainage system (Oldroyd Xv).
- Expanding waterstop (Vandex Expaseal) combined with Vandex Super at vulnerable construction joint between floor and wall.
- Oldroyd Gtx lowers potential for hydrostatic pressure on the waterproofing system (BS 8102 6.4).
