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 Camden.
The River Fleet still runs beneath Camden in a culvert, and properties along its valley line behave differently from those on the higher ground either side. Where the Claygate Member appears towards Hampstead, perched water in the sandy horizons adds a further complication that catches out generic specifications.
Ground conditions
What sits beneath Camden.
| Postcodes | NW1, NW3, NW5 |
|---|---|
| Geology | London Clay, with Claygate Member on the higher ground towards Hampstead |
| Groundwater | Moderate, but the culverted River Fleet influences the valley line |
| Housing stock | Georgian terraces, Victorian villas, converted industrial buildings |
Knowing whether a property sits on the Fleet line changes the design. It is one of the first things we check before quoting in this area.

Specification
Choosing the right system for Camden.
BS 8102 sets out three forms of protection. Which one suits a property in Camden 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.
