Drainage Services in Tadley

Tadley expanded rapidly from the 1950s alongside the growth of nearby employment at Aldermaston, so most of its housing and drainage dates from the post-war period: clay giving way to plastic pipework, separated foul and surface water, and consistent planned gradients. The ground is London Clay overlain in places by sand and gravel, which makes performance patchy — reasonable where gravel caps the clay, poor where the clay is near the surface.

Where clay dominates, seasonal shrink and swell displaces joints and fractures older sections, and soakaways percolate slowly and waterlog after prolonged rain, which is a common cause of standing water on driveways and gardens here. The heathland fringe at Pamber Heath and Baughurst is sandier and drains better, though sand ingress into open joints silts pipework. Outlying villages including Silchester retain older clay drainage and a number of off-mains properties on septic tanks and package treatment plants.

We CCTV survey in Tadley to determine whether a fault is clay-driven ground movement, sand ingress or straightforward blockage, since the remedies differ. Jetting clears silt and root blockages, no-dig lining repairs fractured pipework beneath drives and estate roads without excavation, and surface-water systems on clay ground are sized from measured percolation rather than assumption.
