Basement Waterproofing in Prime Central London
Properties across Kensington & Chelsea commonly include:
Georgian and Victorian terraces with lightwell basements
Multi-storey excavated basements
Listed and heritage buildings
Luxury residential conversions
Mixed-use and commercial lower-ground spaces
Below-ground structures are exposed to continuous hydrostatic pressure from London’s clay-heavy soil conditions. Over time, this can lead to:
Lateral damp penetration
Failed historic tanking systems
Salt contamination of plaster
Timber decay
Structural moisture deterioration
Standard damp proofing is not suitable for basement environments. Specialist waterproofing systems are required.
Our Basement & Cellar Waterproofing Systems
We install professional structural waterproofing systems tailored to the property and intended use of the space.
Type A Cementitious Tanking Systems
A bonded waterproof coating applied directly to masonry to resist water ingress. Suitable for:
Retaining walls
Solid brick basements
Remedial tanking upgrades
Often referred to as basement tanking in Kensington & Chelsea, this method creates a continuous waterproof barrier.
Type C Cavity Drain Membrane Systems
A cavity drain membrane system manages water safely behind the wall structure rather than attempting to block it.
Ideal for:
Luxury basement conversions
Habitable living areas
Multi-level excavations
High-risk groundwater environments
Water is controlled and directed into drainage channels and discharged safely, often via sump and pump systems where required.
This is frequently the preferred solution for high-value properties in Kensington & Chelsea.
