Interior Basement Waterproofing

A complete waterproofing solution that is cost effective and quick to install

How to Waterproof internal walls

Interior basement waterproofing systems are designed to manage any water coming into a property before being pumped back out without affecting the appearance or structural integrity. This innovative approach is quite different to traditional forms of waterproofing such as tanking that is designed to prevent water ingress by using a physical slurry barrier.

In summary, an interior basement waterproofing system controls and channels water using a combination of modern wall waterproofing systems, along with innovative drainage systems and advanced sump pumps that safely remove the water.

Advantages to interior basement waterproofing

Installing an interior basement waterproofing system is generally more affordable than other basement waterproofing systems. Within an average property, it will only takes a couple of days to install and is, generally speaking, far easier to maintain. There is also no need for any expensive exterior excavation. Moreover, as the water is managed and not held back, there is no risk of hydrostatic pressure building up and causing cracks in the basement or cellar walls. This can be a common failure of traditional basement waterproofing such as Tanking, especially in areas where there is a risk of structural movement or vibrations.  

For complete peace of mind, our interior basement waterproofing systems also come with a 10 Year structural waterproofing guarantee with additional insurance backing from GPI available.
