Drainage that keeps working after the retrofit

We provide expert level drainage engineering, applied to ordinary buildings: why water is appearing where it shouldn't, and how to stop it.

• Why flooding is happening, inside or outside the building

• Above-ground drainage, trap seals and smells from the drains

• Below-ground drainage, capacity and condition

• Surface water, SuDS and rainwater on new schemes
