Basement Waterproofing

Basement Waterproofing is the procedure undertaken when water builds up in the ground surrounding the basement, raising the water table and potentially leading to hydrostatic water pressure.

Structural weaknesses can occur if water penetrates through cracks and joints and breaks out onto the basement floor.

Causes & Signs of Built-up Water in your Basement

Investigating the solutions to a wet or flooded basement should be started outside of your home. It is important to make sure all your home’s gutters, downspouts or other drainage systems are working efficiently and are diverting the water away from your home. The grade of soil around the foundation should encourage water to flow away from exterior walls, not toward them.

In many cases, houses and basements can be structurally sound but are not often built to handle water drainage. Failure to slope the ground surface away from the foundation or lack of good gutter or drainage system is common among most properties. The signs that you may have water in your basement are:

  • Condensation on cold walls and floor in summer
  • Damp, humid air
  • Standing water on the floor
  • Water trickling out of walls
  • Staining and blistering of wall covering

Before Basement Waterproofing has taken place

Before Basement Waterproofing procedure has started

This is an image taken before started work. You can clearly see the basement is heavily damaged as a result of water ingress and at this point, it is in desperate need of renovation. The water pressure has exerted on the floor and walls of the basement which can lead to water penetration through cracks, joints and structural weaknesses in the basement.

Our team of highly skilled basement waterproofing contractors controlled the ingress and flow of the water to a pre-determined evacuation point by the use of cavity drainage systems. The flow of the water is controlled through a perimeter drainage channel and directed to a suitable drainage point or sump pump.

Once the cavity wall drainage membrane has been fitted, wall surfaces can be dry lined or plastered directly. Like most traditional tanking systems which work by suppressing the water behind the basement walls, the cavity drain membrane works by preventing pressure from building up against the internal wall structure allowing the structure to breathe out.
