How We Waterproof Basements

Step 1

Survey & Diagnosis

A CSSW-qualified surveyor identifies the source of water ingress and pressure.

Step 2

System Design

We design the correct waterproofing system for the structure and ground conditions.

Step 3

Professional Installation

Tanking, drainage and pump systems installed with long-term guarantees.

Basements We Waterproof

  • Victorian cellars with rising groundwater

  • Older homes without damp-proof courses

  • Properties with external ground above floor level

  • Failed tanking systems

  • Basement conversion projects

  • Rental properties needing compliance

Signs Your Basement Needs Waterproofing

Water problems below ground rarely fix themselves. If you notice any of the following, a waterproofing system may be required.

Water enters after heavy rainfall
Basements that take on water during storms usually lack proper waterproofing or drainage.

Damp patches on basement walls or floors
Moisture appearing below ground level often indicates groundwater pressure.

White salt deposits on masonry (efflorescence)
Powdery deposits show water is moving through the brick or concrete.

Peeling paint or crumbling plaster
Moisture behind finishes causes materials to break down over time.

Musty smells or persistent damp air
A constant damp smell often means moisture is trapped in the structure.

Our Waterproofing Systems

  • Close-up of a person applying mortar to a brick wall with a trowel.

    Cementitious Tanking

    Barrier protection applied directly to masonry.

  • A person wearing black gloves is welding a metal sheet with a grid pattern onto a perforated metal board. The background includes a brick wall.

    Cavity Drain Membrane

    Water is controlled safely behind internal linings.

  • A basement floor with a sump pump system against a brick wall, including a black Zoeller sump pump, an orange float switch, and a drainage grate along the wall.

    Sump Pumps & Drainage

    Captures and removes water from the structure.

  • Living room with a gray sofa, wooden coffee table, flat-screen TV on wooden stand, staircase, and stone wall behind the stairs.

    Basement Conversions

    Waterproofing built into habitable basement spaces.

Patching will not solve pressure.Correct system design will. We assess the structure and install the appropriate tanking or drainage system.

Your Questions, Answered

  • Basements sit below ground level and are exposed to hydrostatic pressure.
    When groundwater builds up around the structure, it pushes against walls and floor junctions until it finds a weakness.

    The damp patch is a symptom.
    The waterproofing system is the issue.

  • Not every basement requires full cement tanking.

    Some structures perform better with cavity drain membrane systems and sump pumps that safely manage water rather than block it.

    Correct system selection depends on:

    • Ground conditions
    • Structure type
    • Intended use of the space

    This is determined during a survey.

  • When correctly specified and installed, structural waterproofing systems are designed for long-term protection.

    Failures usually occur when:

    • The wrong system is chosen
    • Hydrostatic pressure is underestimated
    • Drainage is not incorporated

    System design is more important than the material itself.

  • Work is contained to the affected area.
    Installation may involve:

    • Removing existing finishes
    • Installing membrane systems or tanking
    • Fitting drainage channels and pumps

    We explain the process clearly before work begins.

  • Common signs include:

    • Damp returning in the same area
    • Blown plaster
    • Efflorescence (white salt deposits)
    • Hollow or cracked coatings

    Rigid coatings often fail over time under pressure.
