Surface water and foul drainage done properly, including soakaways sized for the ground you've actually got. We do percolation tests where the spec needs them, install to current building regs, and sign the job off with photos of every connection.
Where soakaway sizing matters we dig a test pit and run a BRE 365 percolation test before quoting. Cornish ground is wildly variable, from free-draining sand to slow-draining clay over rock.
Soakaways sized to BS EN 752 and current building regs Part H, not guessed. Crate systems, traditional rubble pits or shallow infiltration trenches, whichever suits the ground.
1 in 40 for foul drainage as standard, with rodding eyes and inspection chambers at every change of direction. Falls verified with a laser level, not eyeballed.
Every connection photographed before backfill, every chamber benched and signed off with building control. You get a folder of as-built drainage photos at handover.
Yes. New surface-water soakaways for driveways, patios and roof drainage are routine work for us, sized to the impermeable area and the ground type. We test the ground first if there's any doubt.
Yes, where the property is within reach of a South West Water main. We organise the S106 application, install to spec, and have the connection inspected by SWW before backfill.
Heavy Cornish clay over rock sometimes won't soak away at all. In that case we'll look at attenuation tanks with a flow-controlled outfall, or a connection to an existing surface-water sewer. We don't install a soakaway that won't work just to tick a box.
Yes. We'll camera-survey the run, dig down on the collapsed section and replace it with new pipe to fall. Mostly we get called for older clay drainage that's failed under tree roots or settlement.
Yes. AONB and conservation areas around Bude, Newquay and the Roseland need a slightly more careful approach to surface-water management, often using attenuation or shallow infiltration so the landscape isn't disturbed. We've done this work and know what the planners want to see.
A quick call or message with Robert is usually enough to know whether your drainage & soakaways job is a good fit. No detail too small.
