If you go ahead with a basement conversion without waterproofing first, you run the risk of losing your investment. Water will continue to seep into your basement, which can cause flooring to warm, damage paintwork, and make your furniture and possessions mouldy. It can also make the space difficult to keep warm, which will make it an unpleasant space to be in. To counter this, we recommend waterproofing before conversion work begins.

Yes, you can and should waterproof a concrete basement. While the concrete might look solid, small cracks will leave space for moisture to get through. While it might look dry, moisture will build up, creating the ideal damp conditions for mould and mildew to thrive. Basement waterproofing can help to prevent this.

Yes, it is certainly possible to waterproof the inside of a basement. This is a popular method for retro-fitting older basement spaces that either haven’t been waterproofed, or were waterproofed using outdated methods. Instead of digging into your foundations from the outside, we can simply waterproof the space from the inside by creating an impermeable barrier.

To waterproof a basement, we first have to identify any larger spaces where moisture might be getting through an seal them using a range of methods. Next, we apply a cementitious structural waterproofing slurry to the walls and floor of the basement and allow this to dry. Once dried, this layer provides complete protection against moisture. You can then begin decorating your basement with confidence that your space will not become damp or mouldy.

Another method for waterproofing a basement space involves using high-density, polyethylene studded membranes on the walls and floor of your basement. This will allow moisture to move through channels in the membranes where it can be taken to a pump and removed from your basement. If you live in an area with a high water table, this can be very effective for long-term waterproofing.
