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 Holland Park.
Holland Park has some of the largest domestic footprints in west London, which makes below-ground space unusually worthwhile here — a full-width basement under a villa of this size is a significant house rather than a room. The ground is London Clay and generally well behaved, with conditions worsening on the fall westwards towards the Counter's Creek alignment.
Ground conditions
What sits beneath Holland Park.
| Postcodes | W11, W14 |
|---|---|
| Geology | London Clay |
| Groundwater | Generally moderate, increasing on the fall towards Counter's Creek |
| Housing stock | Large stucco villas, garden square terraces, substantial detached houses |
Large footprints mean long perimeters, and long perimeters mean the drainage channel and pump sizing matter more than they would on a narrow terrace. We calculate the inflow rather than scaling up a standard installation.
Holland Park is one of the areas we cover across West London.
Specification
Choosing the right system for Holland Park.
BS 8102 sets out three forms of protection. Which one suits a property in Holland Park 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.
