Type A
Barrier protection
Cementitious slurries and spray applied membranes, forming a continuous barrier against the structure. Suitable where the structure is sound and the head of water is modest and well understood.

Basement waterproofing in Battersea.
Battersea sits on gravels laid down by the Thames, directly connected to a tidal river. Groundwater moves with the tide, and older cellars along the riverside streets frequently show a water line that rises and falls on a predictable cycle. Barrier waterproofing does not hold against that; drained protection does.
Ground conditions
What sits beneath Battersea.
| Postcodes | SW11, SW8 |
|---|---|
| Geology | Thames terrace gravel over London Clay |
| Groundwater | High and tidally influenced near the river |
| Housing stock | Victorian terraces, mansion blocks, new riverside development |
If your cellar floods on a rhythm rather than after rain, that is tidal influence, and it tells us a great deal about how to specify the system.
Battersea is one of the areas we cover across South London.
Specification
Choosing the right system for Battersea.
BS 8102 sets out three forms of protection. Which one suits a property in Battersea depends on the water head, the condition of the structure and what you intend to use the space for.
Type B
Structurally integral
Water-resistant concrete construction, with joints and service penetrations designed as part of the structure. Usually the route for new basements and underpinned extensions.
New build & underpinned structures
Type C
Drained protection
Cavity drain membrane, perimeter channel and a pumped discharge. It manages water instead of resisting it, and it remains maintainable — which is why it suits most conversions of existing cellars.
