Leak, Drainage & Water Ingress Investigations
Water can travel some distance from its source. We investigate likely pathways through roofs, rainwater goods, walls, drainage, plumbing, ground levels and concealed construction.
Leak, Drainage & Water Ingress Investigations with clear findings
The investigation starts with the pattern of the problem and the building context. Depending on the question, it may consider roof and rainwater details, external walls, drainage, plumbing, ground levels and concealed voids.
The aim is to identify the most likely source and route of moisture so any next work is targeted and proportionate.
