Some underground drain problems will require an excavation to gain access to a damaged pipe needing to be repaired or replaced. However once we have confirmed the extent of the damage via CCTV, we may be able to carry out a fast, effective and cost-efficient repair without having to excavate or dig holes on your property, therefore minimising disruption. Subject to inspection, displaced joints, fractures, cracks, root ingress, collapsing/deformed pipework and other faults, may be repaired by installing patch or full liners.
