Drainage Services in Farnborough

Farnborough sits on Bagshot Formation sands and gravels — classic north Hampshire heathland — which generally drain freely and suit soakaways well. The town grew rapidly from the mid-nineteenth century around the railway and the military establishments, so the older parts of Farnborough Street and North Camp still run on Victorian clay pipework, some of it combined, alongside much larger areas of post-war and modern estate drainage.

Sandy ground produces a distinctive failure pattern. Once a clay joint opens or a pipe cracks, fine sand migrates into the drain and voids form around it, so what is reported as a blockage frequently turns out to be a silted, partly deformed section of pipe. Cove and the lower ground towards the Blackwater valley add a shallower water table, where groundwater infiltrates open joints through the wet months. Across the newer estates at Southwood and Hawley the pipework is plastic with separated foul and surface water, and problems there are usually shared private runs and misuse rather than pipe failure.

We CCTV survey Farnborough properties first, both to grade structural condition and to identify sand ingress or infiltration, since neither is solved by jetting alone. High-pressure jetting clears root and silt blockages in the older clay runs, and no-dig lining repairs damaged pipework beneath driveways, block paving and commercial yards without excavation. New surface-water systems take advantage of the free-draining sands, sized from measured percolation.
