Waterproofing a basement

Waterproofing a basement is the first step to converting a dank, damp and miserable space into a safe, dry and habitable room in your property.

More often than not basements reside “below the water table”. This means they are vulnerable to hydrostatic pressure caused by water in the ground that surrounds them. This pressure caused by water against the floor and wall of the basement will often lead to cracks, leaks and eventually damp problems.

For these reasons, If you want to convert the basement in your property into a usable space, then basement damp proofing is essential.

Basement waterproofing systems

Deciding on the best basement damp proofing system will be dependent on the requirements of the building. Typically waterproofing basements involves applying these systems to internal walls and floors. If involved in the project from the construction phase, however,  then we can also apply external waterproofing measures to the property. 

The most common basement waterproofing job we do on a domestic level involves the installation of modern “water management” systems - also known as Type C waterproofing.

This is a popular retrofit solution for basement conversions and basement flats, but we also offer more traditional cementitious solutions otherwise known as basement tanking, along with integrated waterproofing for new build properties and construction projects.

In the industry these are referred to as “Types” of waterproofing and are laid out in British Standards BS 8102:

Tanking a basement to make it waterproof

Tanking is a physical barrier that is applied to basement walls to prevent moisture ingress. This barrier will consist of waterproof slurry or cement which will block any water from getting into your basement.

While tanking is designed to be strong and durable, it can run into problems in areas with overwhelming hydrostatic pressure or anywhere susceptible to ground vibrations.

That is why basement tanking membrane is often used as a solution for earth retaining walls that are suffering from damp problems and leaks. The membrane is fitted to the wall in large plastic sheets. The membrane itself is strong, hard-wearing and waterproof and bumps on its surface create a gap between it and the wall – it is this gap that allows the membrane to deal with any water ingress.

It manages and controls water ingress from the earth surrounding the walls by allowing water to flow into a gap between the waterproof membrane and the basement or cellar wall. It then directs this water into a drainage system to be channelled safely away from the building.

The most complete way to waterproof a basement

The most modern way to waterproof a basement involves managing and channelling any water ingress using hidden drainage systems that work in conjunction with structural waterproofing membranes and high-quality sump pumps.

Cavity drain membranes and drainage systems work together to lower the pressure on the basement walls by managing the build-up of groundwater around the basement. The result is to leave a dry basement fit for any kind of conversion you desire.

The sections below explain how each of these components work:

How much does it cost to waterproof a basement

Every basement waterproofing job is different and the cost will be determined by the size of the property, which basement waterproofing system is installed and the cost of materials and products required.

To accurately arrive at a quotation for how much your basement waterproofing project will cost, then contact our team to arrange a waterproofing survey with one of our specialist surveyors.

Our surveyor will inspect for potential water ingress and signs of dampness and perform an external analysis of the basement or cellar.

If your property already has a waterproofing system installed, our surveyor will perform an inspection of its condition and assess why it has failed to prevent the water ingress problems your property is suffering from.

You will receive a full and thorough survey report detailing their findings along with an itemised bill to conduct the works should you choose to proceed.
