Basement Excavation in Taunton SW — Digging Out the Space Below

Basement excavation is needed for domestic basement conversions, new basements, and commercial basements. It suits sites where additional space is required below ground, including restricted access sites where compact equipment is needed.

Typical basement excavation projects include domestic basement conversions, new residential basements, and commercial basements.

Basement excavation is the process of digging out the space for a basement, either by removing the existing ground beneath a property or by excavating a new basement box. The excavation must retain the surrounding ground (often with contiguous or secant piling), manage groundwater, and avoid undermining the existing structure. We coordinate the excavation with the retention and the waterproofing, so the basement is dug safely and the structure above is protected.

We install the retention (often a pile wall), excavate the basement box, manage any groundwater, and form the basement slab and walls. We coordinate with building control throughout and ensure the existing structure is supported at every stage.

Basement excavation cost depends on the volume of excavation, the retention required, the groundwater management, and the disposal of arisings. Access and the depth also affect cost. We provide a fixed quote within 48 hours of the site visit.

How do you protect the house during basement excavation?

We retain the surrounding ground — often with contiguous or secant piling — before excavating, so the ground is supported and the existing structure is not undermined. We also manage groundwater and support the existing foundations where required. The retention is designed for the specific site.
