Waterproofing stairs with basement beneath

We install York Stone and Victorian tiles on front stairs to traditional Victorian properties. These stairs sometimes have some form of basement or living space below and as such are required to be thoroughly waterproofed.

We install various systems based on the situation and they are  effective. We are however primarily a tiling company so we would recommend that if you are having a complex problem with water ingress its best sorted out by a dedicated waterproofing company.
