When the existing drainage was sized for a smaller roof, fewer paved surfaces or a different rainfall pattern, the system gets overwhelmed and water pools at the lowest point on the property. Three things drive most modern surface water problems in our area: new extensions and outbuildings that add roof area without upgrading the drainage; driveway re-surfacing in impermeable materials (block paving without sub-base drainage, resin-bound over compacted clay) that converts permeable ground into hard standing; and ageing [soakaways](/services/soakaways) that have silted up and lost their original infiltration capacity. We diagnose the actual cause — not just treat the symptom — and design a system sized for your property's roof area, hard standing area, soil type and rainfall data. The right design is the difference between a fix that lasts 30 years and a fix that fails the next time we get a one-in-twenty rainfall event. ## What Standing Surface Water Does to Your Property Surface water against a wall is the single most common cause of damp in residential properties built before 1990. Once water saturates the ground beside a foundation, it tracks horizontally through the wall, defeats the damp-proof course and shows up as rising damp inside — which is rarely 'rising damp' at all, but lateral penetration from a surface water defect outside. Repeated saturation around foundations causes ground heave in clay soils and ground subsidence in sandy soils. Both crack walls. Both invalidate buildings insurance claims if the underlying cause (surface water mismanagement) was reasonably foreseeable and not addressed. On driveways and paths, repeated freeze-thaw cycles in ponding water destroy block paving sand joints, lift slabs, and crack tarmac. The cost of replacing a 50m² driveway because the underlying drainage was wrong is roughly ten times the cost of getting the drainage right in the first place. Waterlogged lawns die. Compacted, saturated soil suffocates grass roots and creates the perfect conditions for moss, rush and broadleaf weeds to take over. Once a lawn is gone, restoring it requires either complete returfing or a multi-season recovery programme — neither of which works while the drainage problem remains. ## Our Surface Water Diagnostic & Design Process 1 ### Site Survey We walk the property, identify ponding points, trace existing surface water connections, and assess soil conditions. For larger schemes we carry out a percolation test. 2 ### Catchment & Capacity Calculation We measure roof and hard-standing catchment area and calculate required drainage capacity to BS EN 752 and Building Regs Part H — sized for at least a 1-in-30-year storm event. 3 ### Solution Design Based on soil type, catchment, available space and existing infrastructure, we design the right combination of [soakaway](/services/soakaways), French drain, channel drain, attenuation crate or surface water sewer connection. 4 ### Installation We install everything ourselves — [excavation](/services/excavations-new-drains), geotextile lining, granular fill, crate systems, pipework, connections and surface reinstatement. No subcontractors. 5 ### Test & Sign Off On completion we test the system with controlled flow, confirm correct gradients and provide as-built drawings for your records and any Building Control sign-off. ## Why Our Approach Works When DIY Doesn't ### Proper Sizing Most failed surface water installations are undersized. We calculate catchment area and size the system to actually cope with peak rainfall events. ### Percolation Testing We test soil infiltration rates before designing soakaways. Sand needs different sizing than clay — getting this wrong is why so many soakaways fail in year 2. ### Multi-Element Solutions Real-world drainage problems usually need two or three elements working together: a French drain to intercept flow, a soakaway to dissipate it, and a channel drain to handle hard-standing run-off. ### Building Regs Compliance All work designed and installed to Part H. Building Control notification handled as part of the project where required. ### Existing System Diagnosis Before we install anything new we diagnose why the existing system isn't coping. Sometimes a £200 jetting job restores capacity and avoids £4,000 of unnecessary new installation. ### Long Workmanship Guarantee All installation work carries a 12-month workmanship guarantee. Crate systems and pipework carry manufacturer warranties of 25–60 years. ## Soakaways, French Drains & Attenuation Explained A soakaway is an underground void filled with granular material or modular crates that allows surface water to infiltrate slowly into the surrounding soil. Sizing is governed by BRE Digest 365 — the soakaway must be large enough to hold the peak storm volume plus an infiltration safety factor based on measured soil percolation rate. [Soakaways](/services/soakaways) must be at least 5 metres from any building and clear of other services. Modular [soakaway](/services/soakaways) crates (such as Polypipe Polystorm, Wavin AquaCell or Hydro StormCell) have largely replaced traditional rubble-filled pits. Crates provide around 95% void ratio compared to 30% for granular fill, meaning a crate soakaway is roughly one-third the size of an equivalent rubble pit. They also have predictable structural performance, allowing installation under driveways and access roads with appropriate cover slabs. French drains are linear trenches filled with granular material, with a perforated pipe at the base, designed to intercept and convey water rather than dissipate it. They are ideal for waterlogged lawns where water is flowing across the property surface or perching above an impermeable clay layer. The intercepted water is normally conveyed to a [soakaway](/services/soakaways), a surface water sewer or a discharge to a watercourse. Channel drains (linear gully systems such as ACO Drain) handle high-flow surface run-off from driveways, patios and paved areas. They sit flush with the hard surface and grade water across the full width of the area into the drainage system. Capacity is determined by the grating slot area, the channel cross-section and the outfall gradient. Attenuation systems store peak storm flow and release it slowly into the existing surface water sewer at a controlled rate. They are commonly required when an extension or new build increases run-off to a connection that cannot accept the full peak flow. Attenuation crates with a flow control device (vortex regulator or orifice plate) keep the discharge within the rate agreed with the local authority or water company. Building Regulations Part H Section H3 sets the hierarchy for surface water disposal: infiltration first ([soakaway](/services/soakaways)), then watercourse (river, stream, lake), and only as a last resort to a surface water sewer. Discharge to a combined sewer is no longer permitted for new connections. We design every system to this hierarchy and document the justification for any required exception. ## Frequently Asked Questions How much does a new soakaway cost? Will a French drain fix my waterlogged lawn? Can I connect surface water to my foul drain? Do you handle Building Control notifications? Why does my old soakaway no longer work? How long does installation take? ### Related Services - [Soakaways](/services/soakaways) - [Excavations & New Drains](/services/excavations-new-drains) - [Gully Cleaning](/services/gully-cleaning) - [CCTV Drain Surveys](/services/cctv-drain-surveys) ### Service Areas - [Bournemouth](/areas/bournemouth) - [Poole](/areas/poole) - [Christchurch](/areas/christchurch) - [Dorchester](/areas/dorchester) - [Weymouth](/areas/weymouth) - [Wimborne](/areas/wimborne) - [Wareham](/areas/wareham) - [Dorset](/areas/dorset) - [Swanage](/areas/swanage) - [Bridport](/areas/bridport) ## Ready to Solve Your Drainage Problem?
