Persistent puddles, saturated lawns and overflowing gullies are common signs that surface water has nowhere to go. We install soakaways that disperse rainwater safely back into the ground, helping prevent damp issues and erosion. Our team works across SE3, including routes around Blackheath Common and Blackheath Village. Every installation is planned to suit your site, not a one-size-fits-all trench.
Blackheath’s mix of Georgian townhouses, Victorian villas and period conversions often comes with mature planting, tight side access and older drainage layouts. We regularly design systems for front drives, rear courtyards and shared access paths, keeping disruption low. If you’re in Greenwich, Lee, Lewisham or Kidbrooke, we’ll assess levels, existing pipework and where water currently pools. That local context helps us choose the right soakaway type and location first time.
We start with inspection and, where needed, percolation tests and sizing calculations to match expected runoff. Then we install either modern crate systems or traditional rubble soakaways, add inspection chambers for future access, and connect to gullies or channel drains correctly. Work is carried out to Building Regulations guidance, with neat reinstatement and clear aftercare. Homeowners choose us for straightforward communication, punctual scheduling and a 10-year warranty on workmanship.
The soakaways Blackheath area needs often depend on variable ground conditions, mature tree roots and constrained access near period properties. We plan excavations around utilities, manage spoil responsibly and factor in parking and delivery restrictions that can apply around SE3. Where properties sit close to boundaries between borough responsibilities, we keep documentation clear and ensure the drainage approach is compliant. Our layouts also account for protecting neighbouring walls and shared paths common in conversions.

Costs vary with soakaway size, depth, access, and whether you need percolation tests or new drainage runs. As a guide, a small rubble soakaway for a single downpipe may start around £900–£1,500. A larger crate system serving a driveway or multiple downpipes is often £1,800–£3,800+. Complex jobs with long connections, restricted access or extensive reinstatement can reach £4,500–£7,000.
Most installations take 1–3 days on site, depending on excavation depth, access for machinery, and the amount of pipework to connect. A straightforward crate soakaway with a short run from a gully can sometimes be completed in a day. If percolation testing, multiple connections, or careful hand-digging around services is required, allow 3–5 days. Weather and ground conditions can also affect timings.
In many cases, a soakaway in a garden or driveway is permitted development and doesn’t need planning permission, provided it manages surface water on your property and doesn’t affect neighbours. However, rules can change for listed buildings, conservation areas, or works that alter highway drainage. We check the site details, advise on any permissions, and design to relevant Building Regulations guidance. If approvals are needed, we’ll help you prepare the information.
We provide a 10-year warranty on workmanship for our soakaway installations, covering defects caused by installation errors such as poor connections, incorrect bedding, or inadequate assembly of the system. The warranty doesn’t cover misuse, damage from third-party works, or extreme events beyond design assumptions. We also recommend periodic inspection of chambers and gullies to keep the system performing well. Warranty terms are confirmed in writing before work begins.
We install modern crate systems (high-capacity modular units wrapped in geotextile) and traditional rubble soakaways, selecting the best option for your space and soil. Designs can include inspection chambers, silt traps, and separate connections for downpipes, channel drains or patio gullies. We’ll advise on depth, footprint and location based on percolation results and runoff calculations. Where access is tight, we can tailor excavation methods and reinstatement finishes.
