Standing water around planters, patios or podium decks can quickly lead to damp, algae and slipping hazards. Our drainage solutions are built for the realities of E14, from landscaped courtyards near One Canada Square to riverside walkways by Crossrail Place. A properly designed French drain captures runoff and redirects it to a suitable outlet before it becomes a problem. The result is a cleaner, safer outdoor space that drains predictably after heavy rain.
Canary Wharf properties are often modern high-rise apartments, waterfront developments and penthouses with engineered terraces and shared amenity gardens. These spaces can have limited soil depth, complex build-ups and strict management-company requirements. We regularly work across the Isle of Dogs and nearby Poplar, adapting our methods to podium slabs, raised beds and tight service routes. If your outdoor area floods after storms, we’ll specify a system that suits the structure and finishes.
We start with a site assessment to map flow paths, levels and the best discharge point, then create a gradient design that keeps water moving. Installation includes trench excavation, geotextile membrane, perforated pipe, gravel fill and a secure outlet connection, with options for multiple runs where needed. We protect surrounding paving and planting, keep disruption low, and leave clear maintenance guidance. Homeowners and managing agents choose us for precise workmanship, transparent scopes and dependable aftercare.
In the London Borough of Tower Hamlets, access can be controlled by concierge desks, loading bays and timed deliveries, so we plan logistics carefully. Many E14 schemes have podium gardens and waterproofing layers, requiring shallow, precise excavation and clean detailing. We also account for high rainfall runoff from hard landscaping and roof terraces, ensuring outlets are suitable and compliant. If parking is restricted, we organise materials and waste removal to keep the site orderly.

Costs vary with length, depth, access and whether we need multiple runs. As a guide, small installations for a terrace edge or planter line often start around £1,200–£2,500. Medium runs across a courtyard are commonly £2,500–£5,500. Complex podium-garden work, restricted access, or new outlet connections can push totals to £6,000–£10,000+. We provide a detailed written breakdown after a site visit.
Most straightforward French drain installations take 1–2 days, including trench excavation, pipework, gravel fill and reinstatement. Larger layouts with multiple runs typically take 2–4 days. Timescales depend on access restrictions in apartment developments, the need to protect waterproofing layers, and how far we must route the outlet connection. Weather can also affect progress, especially if ground conditions are saturated.
French drains are usually classed as minor garden works and don’t require planning permission for most homes. However, rules can change if you’re in a listed building, a conservation area, or altering drainage discharge points. Apartment blocks and managed developments may also require freeholder or management-company approval. We’ll advise what’s likely needed, check constraints, and ensure the outlet connection is appropriate before work starts.
Yes. Our French drain installations come with a 10-year warranty covering workmanship and correct installation of the system components (pipe, membrane, gravel placement and connections). It’s designed to give you confidence that the drain will perform as specified when maintained. The warranty doesn’t cover blockages caused by external factors such as building debris, oil spills or unmaintained leaf build-up, but we provide maintenance guidance and can service the system.
We tailor the design to your space and build-up. Options include different pipe diameters, rigid or flexible perforated pipe, and graded gravel sizes to match flow requirements. We can add silt traps, inspection points for easier maintenance, and multiple runs for larger courtyards. Geotextile membrane specifications can vary depending on soil fines and planting. We’ll recommend the best combination after checking levels, surfaces and the intended outlet.
