Basement & Cellar Waterproofing

A wet basement or cellar does not have to stay that way. We design and install complete waterproofing systems that keep your below-ground space permanently dry.

What Is It?

Understanding Basement Waterproofing

Basement waterproofing involves creating a barrier between the structure and groundwater to keep below-ground spaces dry. There are three recognised systems — Type A (barrier protection), Type B (structurally integral), and Type C (drained protection) — and the right solution depends on your specific property and water table conditions.

High water table or hydrostatic pressure against the structure
Failed or absent original waterproofing
Cracks or defects in the basement structure
Inadequate drainage around the building

Our Approach

How We Treat Basement Waterproofing

We design bespoke waterproofing systems to BS 8102 standards. For most residential basements we install a Type C cavity drain membrane system — a studded membrane fixed to walls and floor that channels water to a sump and pump unit for automatic discharge. Where appropriate we also apply cementitious tanking or structural waterproofing. All systems are designed by our qualified surveyors and installed by our in-house team.
