Groundworks set the standard for everything that follows, whether you’re building an extension or reshaping a garden. Our team supports homeowners across DA1 and DA2 with safe excavation, drainage upgrades and strong foundations. We regularly work around busy routes near the Dartford Crossing and properties close to Central Park, planning access and spoil removal carefully. Expect clear communication, neat working practices and a site that’s left organised at the end of each day.
Dartford’s mix of Victorian terraces, 1930s semis and new developments means no two sites behave the same. Older homes often need careful trial holes and protection around existing services, while modern plots can require precise levels for patios, paths and driveway build-ups. In areas such as Wilmington and Greenhithe, we frequently see projects where drainage and falls are just as important as the finished surface. We tailor our method to your property, your neighbours and the practical realities of the street.
We start with a site visit to confirm levels, access, underground services and the best sequence of works. You’ll receive a detailed scope covering site clearance, levelling, foundations, drainage runs, concrete work and any retaining walls or access roads required. Our team works to current standards, keeps disruption down, and documents key stages so you know what’s been done and why. Homeowners choose us because we’re consistent, careful, and we stand behind our workmanship.
Across Dartford Borough, we often encounter variable ground and tight access, especially on terraced streets and busy commuter routes. Parking and deliveries can be tricky near major links, so we plan skips, grab lorries and concrete pours to minimise disruption. We also factor in surface water management, existing manholes and shared drains that are common around older housing. Our approach keeps your project compliant, practical and build-ready.

Costs vary with access, depth of dig, spoil removal and whether you need drainage or reinforced concrete. As a guide in the Dartford area, small excavation and levelling jobs often start around £800–£2,500. Drainage installs and concrete bases commonly fall between £2,500–£8,000. Full groundworks for an extension (foundations, drainage, slab prep) are typically £8,000–£25,000+. We’ll provide an itemised estimate after a site visit.
Timescales depend on the scope and what we uncover once we start digging. For many homes in DA1–DA2, site clearance and levelling can take 1–3 days, while a concrete base may take 3–7 days including curing time. Foundations and drainage for an extension often run 1–3 weeks. Weather, restricted access, inspections, and unexpected services or poor ground can extend the schedule.
Many garden and driveway groundwork projects are permitted development, but there are important exceptions. Changes to drainage (especially connecting to sewers), works near boundaries, and new or altered access points can trigger permissions or require approvals. If you’re laying a driveway, permeable surfacing and correct runoff management are key. We’ll advise what’s likely needed, check constraints relevant to Dartford Borough, and coordinate with your designer, builder or engineer where required.
We provide a 10-year warranty on our workmanship for eligible groundwork elements, including installed drainage runs, concrete bases and retaining structures where specified. The warranty covers defects arising from installation issues, not damage caused by third parties, ground movement beyond reasonable expectations, or changes made after completion. We also keep records of the build-up and materials used, so any concerns can be assessed quickly. Warranty terms are confirmed in writing before work starts.
Groundworks can be tailored to suit your build and finish choices. Popular options include reinforced concrete slabs, trench-fill or traditional foundations, soakaways and channel drains, and Type 1 sub-bases for patios or driveways. For level changes, we build retaining walls in concrete block, timber sleepers or engineered systems depending on height and loading. We’ll help you choose based on ground conditions, budget, intended surface (paving, resin, turf) and long-term maintenance.
