We also have experience in surveying and installing both external and internal Type A waterproofing systems to British Standards that can usually be carried out in both new builds and existing structures. These can be installed internally within the building, or externally:
External Type A membranes
With new builds, or new below-ground structures this can offer us the chance of installing external Type A waterproofing system that often comes in the form of a composite sheet membrane that we would install prior to the structure itself. This robust membrane is usually ‘pre-applied’ meaning we would lay the membrane on site prior to the casting of the concrete structure.
We have also carried out liquid waterproofing applications to the external perimeter of the ground floor level, or basement capping beams up to the DPC level that often is not considered when looking just at the basement internal area, although is a ‘high risk’ location. Please also see our Deck Waterproofing Systems section.
