Basement waterproofing — Protect your home from moisture entering from below

A musty smell, mould on the walls or puddles on the basement floor? Groundwater may be entering through the floor or walls. A damp basement is more than an inconvenience: it can damage your home, affect air quality and even your health. Timely, properly carried out basement waterproofing prevents further problems and increases the value of your home.

Left untreated, persistent moisture can damage walls and foundations, weaken the structure and compromise the stability of your home.

What is basement waterproofing?

Basement waterproofing makes your basement structurally watertight. A suitable technique or combination of techniques is chosen according to the severity and source of the damp problem. This prevents groundwater from entering and spreading to other parts of the house.

Signs of a damp basement

Do you recognise one or more of these signs? It is time to act:

  1. Water ingress during rain or when groundwater levels are high

  2. Wet patches on walls and floors, or puddles on the floor

  3. Mould on walls or in corners

  4. Loose plaster or peeling paint

  5. A strong musty smell

Even if your basement is only used for storage, moisture can cause lasting damage to walls, materials and health.

  2. Structural damage to walls and foundations

  3. Damage to stored belongings and furniture

  4. Higher humidity throughout the home

How do we tackle basement problems?

Every basement is different. Our tanking treatment always uses three waterproofing layers. Depending on the situation, we may also excavate around the basement, remove the surrounding soil and waterproof the walls from the outside.

We apply three layers of waterproof cement or coating to the prepared basement walls and/or floor.

Tanking — traditional basement waterproofing

  • Suitable for visible leaks or active water pressure
  • Always three waterproofing layers, with proper preparation and drying time
  • Complete waterproofing from the inside

Where necessary, we excavate around the basement and remove the surrounding soil to reach the exterior walls. We then treat the walls from the outside to help prevent moisture entering.

Exterior waterproofing — where needed

  • Exterior walls exposed by removing the surrounding soil
  • Waterproofing applied directly to the outside of the basement
  • Used where needed alongside our three-layer tanking treatment
Wall injection against rising damp: plaster removed and injection holes along the base of the wall.

When ground moisture rises through basement walls, a damp-proofing product is injected into the masonry.
