Done properly, water is captured at the low point, piped to a correctly sized soakaway, and gone. Done badly, it pools against your house. ### Who it's for Anyone installing a new driveway or patio (SuDS regs almost always apply), homeowners with a boggy lawn or a garden that floods after rain, and property owners across Bucks and Surrey dealing with water tracking into garages, sheds or the house itself. ### When you need it You need drainage when water pools on your driveway or patio, when your lawn is squelchy for days after rain, when a garage or outbuilding takes water at the base, or when planning rules require a soakaway as part of a new driveway install. ### Why professional installation matters Drainage is invisible until it fails, and then it's catastrophic. Undersized soakaways fill and back up within a season. ACO channels laid without fall don't move water. Land drains without stone surround silt up in a year. We size, fall and install every element to Building Regs / SuDS spec, first time. ## What Happens If You Leave It Small problems don't stay small. Here's what we see when homeowners delay, and the corner-cutting mistakes that make it worse. ### Water pooling against the house Poor drainage sends surface water toward foundations, DPCs and cellar walls. Once it gets in, damp treatment and repair costs are into the thousands. ### Soakaway backflow and blowout An undersized soakaway floods after every heavy shower, then backs up through the ACO channels and floods the driveway from the drain end. ### Bog-lawn and rotting fence posts Poor sub-soil drainage keeps the lawn saturated for days, rots fence post bases, kills grass and turns everything into mud. ## Our Drainage Process A clear, in-person system from first visit to final handover, no surprises, no scope creep. 1. 1 ### In-person site survey We identify low points, existing drainage runs, soakaway locations and highway/foul connections. Test soil percolation where a soakaway is planned. 2. 2 ### Fixed written quote, same day Itemised for excavation, pipework, crates/rubble, channels, gullies, membrane and connections. No mystery figures. 3. 3 ### Excavation & pipework Trenches dug to correct fall (minimum 1:80 on surface water), 110mm SDR-11 pipework laid on a granular bed, jointed and pressure-checked. 4. 4 ### Soakaway or connection Modular soakaway crates installed at correct depth, wrapped in geotextile, backfilled with drainage stone. Or connections made cleanly to existing surface water systems. 5. 5 ### Reinstatement & handover Ground reinstated, ACO channels bedded flush and gullies levelled. Test with hose to confirm flow. 12-month workmanship guarantee starts. ## Why Homeowners Choose Hi Design ### Dry driveways and patios Surface water goes where it should, into the ground safely, not against your house or across your paving. ### SuDS compliant, planning safe Correctly sized soakaways keep new driveways inside Permitted Development rules, no planning application required. ### Solved, not seasonal A properly designed soakaway lasts 30+ years without attention. Blocked gullies and bog-lawns become a one-time fix, not an annual problem. ## Drainage: The Detail ### Channel drains, gullies and linear systems ACO HexDrain, Multiline and Q-Max channels installed across driveways at low points, garage entries and threshold drops. Channels bedded on a concrete haunch with 1:80 fall to the outlet, connected via 110mm SDR-11 pipe to the soakaway. Cast-iron or galvanised gratings for domestic loads; ductile iron D400 for commercial and vehicle-crossed points. ### Soakaway sizing and construction Soakaway volume is sized against roof/paved catchment area and local percolation rate, typically 1m³ of storage per 20m² of impermeable area on average Bucks soil. Standard build is modular crates (Aquacell, Rainstore3) wrapped in a geotextile membrane, backfilled with 20–40mm clean stone. Located minimum 5m from any building and downhill of foundations. BRE Digest 365 compliant. ### French drains and land drainage For waterlogged lawns and gardens we install French drain runs: 300–450mm wide trenches with a perforated 100mm land drain pipe bedded in 20mm shingle, wrapped in a geotextile membrane and backfilled with more shingle to within 100mm of the surface, topped with topsoil. Runs typically at 3–5m spacing on heavy clay, all falling to a discharge point or soakaway. ### Permeable driveway construction The alternative to a soakaway is a fully permeable driveway construction, Priora block paving or resin bound over an open-graded Type 3 sub-base. Water drains vertically through the surface into the sub-base, which acts as an attenuation layer. Ideal for SuDS compliance on new driveways without space for a separate soakaway. ### Residential vs commercial Residential: 110mm SDR-11 pipework, modular crate soakaways, HexDrain-grade channels. Commercial: heavier-grade SDR-9 pipework, larger attenuation tanks, D400 grating throughout, silt traps and interceptors. We install both, and coordinate with drainage engineers on larger schemes. ## Drainage, Common Questions ### Do I need a soakaway for my new driveway? ### How much does a soakaway cost to install? ### How long does drainage work take? ### Will a soakaway work on clay soil? ### Can you unblock my existing drains? ### How deep should a soakaway be? ### What guarantee do you offer on drainage? ### Can drainage be added to an existing driveway? ## Related services & areas Block Paving: https://www.hdlandscapingandpaving.co.uk/services/block-paving Resin Driveways: https://www.hdlandscapingandpaving.co.uk/services/resin-driveways Tarmac Driveways: https://www.hdlandscapingandpaving.co.uk/services/tarmac Patios & Paving: https://www.hdlandscapingandpaving.co.uk/services/patios Chesham: https://www.hdlandscapingandpaving.co.uk/areas/chesham Amersham: https://www.hdlandscapingandpaving.co.uk/areas/amersham Contact: https://www.hdlandscapingandpaving.co.uk/contact Home: https://www.hdlandscapingandpaving.co.uk/ ## Solve The Water Problem, Properly Free in-person survey with percolation check.
