Concrete Raft in Taunton SW — A Foundation That Spreads the Load

Concrete rafts are chosen where the ground is weak or variable, where the building loads are light enough to be spread, and where piling is not justified. They suit residential extensions, light commercial structures, and sites with made ground or soft soils.

Typical raft projects include residential extensions on weak ground, light commercial structures, and sites with made ground where a raft spreads the load more effectively than strip foundations.

A concrete raft is a reinforced slab that covers the whole building footprint, spreading the load so evenly that the ground does not need to be strong at any single point. The raft is reinforced to handle the bending forces, and the edge is often thickened to form a toe. Rafts are used where the ground is weak or variable, where the loads are relatively light, and where a deep foundation is not justified.

We assess the ground and the loads, then design the raft — thickness, reinforcement and edge detail. Our team prepares the formation, fixes the steel, sets the formwork, and places and finishes the concrete. We coordinate with building control throughout.

Concrete raft cost depends on the area, the thickness, the reinforcement, and the volume of concrete. The ground conditions and the edge detail also affect cost. We provide a fixed quote within 48 hours of the site visit.

Is a concrete raft the same as a reinforced concrete raft?

Yes. A concrete raft is a reinforced concrete slab that spreads the building's load across the whole footprint. The reinforcement is essential — without it the slab would not handle the bending forces. We design and build the raft in-house.
