Basement tanking (or waterproofing) involves applying waterproof coating or membranes to the outside of your basement conversion to keep it dry and comfortable. This doesn’t just prevent damp or mould from developing – it actually ensures that your basement is structurally sound. If a conversion is improperly waterproofed, the brick work can decay and the interior can also be damaged, in a worst-case scenario this can involve flooding.
With a wealth of experience, our team is confident in the materials and techniques that they use to tank basement conversions. In some instances, a pumping system is required while excavating and building the exterior of the basement to keep the area dry and remove ground water, grey water, or effluent. Once the tanking has been installed, these pumps may no longer be necessary and the membrane system will prevent water from filtering through into your basement or damaging the exterior walls.
Keeping the Basement Waterproof
In some instances, we have to install a permanent water pump if natural drainage isn’t possible. The pump will remove water that accumulates in a designated pit and redirect it to a main drain. These pumps are run off the main electricity supply and have a battery back up in case of a power outage – they should not have a significant impact on your electrical bill.
Our quality and product guarantees extend to our waterproofing systems, which are also guaranteed by the manufacturers. We used the same suppliers for many basement conversions in London, and only ever use proven and tested products for such an important aspect of the build.
