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 Notting Hill.
The clay under Notting Hill was dug for bricks before the area was built on, and the ground reflects that history — made ground and backfilled workings turn up more often here than the smooth geological map suggests. To the west, Counter's Creek runs in a culvert with a documented history of surface and sewer flooding behind it.
Ground conditions
What sits beneath Notting Hill.
| Postcodes | W11 |
|---|---|
| Geology | London Clay, with brickearth over the higher ground |
| Groundwater | Moderate, rising towards the culverted Counter's Creek on the western edge |
| Housing stock | Stucco terraces, garden square housing, large converted villas |
The garden square houses convert well because the footprints are generous, but the ones sloping down towards the Counter's Creek line need the drainage strategy thought through properly rather than assumed from the neighbours.
Notting Hill is one of the areas we cover across West London.
Specification
Choosing the right system for Notting Hill.
BS 8102 sets out three forms of protection. Which one suits a property in Notting Hill 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.
