One of the few groundworks contractors in Kent, Surrey and Sussex offering raft foundations, the specialist solution for difficult ground.
DPC Groundworks provides professional raft foundation and groundworks services across Kent, Surrey and Sussex, including Tunbridge Wells, Copthorne, East Grinstead and surrounding areas.
Raft foundations are designed to spread the weight of a building across a large reinforced concrete slab. They can be an effective foundation solution for new builds, house extensions, garden rooms, garages and other structures, particularly where ground conditions or structural design make traditional foundations less suitable.
We can undertake the complete groundwork package required to bring your project up to slab level, including:
A raft foundation is only as good as the ground preparation beneath it. At DPC Groundworks, we take care to achieve the correct levels, properly compact the sub-base and install reinforcement accurately before the concrete is poured.
We work from the structural engineer’s drawings and specifications, ensuring the raft is constructed to the requirements of each individual project.
Whether you’re building a new home, extension, garden building or garage, DPC Groundworks can manage the excavation, drainage, reinforcement and concrete works required for your raft foundation.

Ground conditions across the Tunbridge Wells, Kent, Surrey and Sussex area vary a lot, from sandstone and clay to made-up ground on older plots. We've worked this ground for over 20 years, so when a raft is the right answer, we know it, and when it isn't, we'll tell you straight rather than sell you something you don't need.
Not sure whether your site needs a raft, strip, or trench-fill foundation? Send us a few photos and any engineer's report you have, and we'll give you an honest steer, free of charge.
Not necessarily. While the slab itself uses more concrete and reinforcement, you often save on excavation depth and time. On difficult ground, a raft can work out more cost-effective than deep traditional footings.
For a typical extension, excavation through to a cured pour usually runs 1–2 weeks, depending on size and weather. We'll give you a firm timeline as part of your quote.
Yes, raft foundations are designed by a structural engineer based on a ground investigation. If you don't have one yet, we can point you toward engineers we've worked with before.
Always. We build exactly to the specification provided and stay in contact with your design team throughout.
