Basement waterproofing in Fulham.
Fulham is one of the most active basement conversion markets in London and one of the least forgiving. The terrace gravels beneath it are permeable and connected to the tidal Thames, so water arrives under real pressure. Party wall considerations are also unavoidable at this terrace density.
Ground conditions
What sits beneath Fulham.
| Postcodes | SW6 |
|---|---|
| Geology | Thames terrace gravel over London Clay |
| Groundwater | High and tidally influenced across most of the area |
| Housing stock | Victorian terraces at high density, mansion blocks |
Terrace density means most Fulham jobs involve party wall awards and neighbouring-owner notice. We work alongside your surveyor and sequence the waterproofing around that programme.

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