Tanking - Underground Waterproofing

Sansoms are specialists in tanking (underground waterproofing), to foundations, lift pits, basement car parks or any underground structures that must be waterproof.

Sansoms are licensed applicators for the Volclay Bentonite membranes. These are applied during construction (and backed up by QA checks and manufacturer's warranties).
