Drainage in Solihull runs into trees again, and on this occasion below ground rather than above it.
Root ingress is the single most common drainage fault we are called to here. Roots find a joint or a hairline crack in an older clay run, get in, and then thrive on exactly what is flowing past them. On a wooded plot that is not an occasional problem, it is close to inevitable in any run that is not fully sealed. The symptom is a drain that blocks every few months and clears when it is rodded, which people treat as bad luck rather than as a structural fault in the pipe.
Clearing it repeatedly is money spent on the symptom. A camera survey shows exactly where the ingress is, and the choice is then between lining the affected length and replacing it. We would rather price the fix than sell you an annual visit.
Surface water is the second consideration on these plots, because a large roof and a large area of hard surfacing generate a great deal of water. A soakaway must be sited a sensible distance from the building and the boundary, must be sized against the area draining into it, and must be in ground that actually accepts water, which is a test rather than an assumption. Siting it under a mature canopy is asking for the same root problem again.
In the Green Belt villages a good number of properties run on private treatment systems. Our drainage work page covers surveys, repairs and new connections.
