Groundworks

We understand that every great build begins with solid groundwork. Our expert groundworks services provide the essential foundation upon which all successful construction projects are built. With years of experience serving clients across London, Surrey, and the surrounding areas, we take pride in delivering precision, reliability, and durability in every phase of the groundwork process.

From initial site preparation and excavation to drainage, foundations, and concrete works, our team handles every detail with care and technical expertise. We use advanced equipment, proven techniques, and high-quality materials to ensure each site is perfectly prepared for construction — safe, stable, and compliant with all regulations. Whether for residential, commercial, or industrial developments, our groundworks solutions are tailored to meet the specific requirements of your project.

Every solid build starts below ground, before laying any bricks or beams. Banstead Construction provides groundworks services for homeowners and developers who need the site properly prepared before construction begins. As an established groundwork company, we have handled several different projects, from small residential to commercial, and we understand that the wrong approach at this stage can cause problems that surface years later.

When you are looking for “groundwork contractors near me”, you will find many choices, but few possess the expertise our groundwork specialists offer with clear and honest communication. From house extensions and upgrades to commercial groundworks, we prepare your site to the highest standard.

We offer a full range of groundworks for various projects and site conditions.

• Excavation services for foundations, basements, and whole building footprints
• Foundation work including strip, trench fill, and raft foundations
• Installation of drainage systems including foul water, soakaway systems, and surface water
• Groundworks for extensions, site preparation before structural and building work
• Site clearance, vegetation clearance, and removal of existing structures before excavation work

Every site is assessed separately before beginning projects. Sites are unique due to soil type, ground conditions, and access, so we adjust our procedures accordingly and do not use a one-size-fits-all approach to our excavation and foundation work. Your project is always coordinated from start to finish with our internal connection between our structural works and house extension services.

We start the groundwork projects systematically with a site visit to assess soil conditions, drainage requirements, and accessibility. Then, all the vegetation, debris, and any existing structures are cleared before excavation starts to the depth specified in the structural drawings. After that, the foundations are laid, drainage systems are installed, and the site is made ready for the next phase of construction. Throughout, we monitor weather and ground conditions to ensure a successful project on schedule with no extraneous delays or costs.

The groundworks cost will vary depending on the site size, soil type, and the works to be carried out. The excavation cost is influenced by the condition of the ground, as areas with clayey soil or rocks can make it harder to dig and may need more time, specialist equipment, and additional labour to manage safely. Foundation cost depends on the foundation type specified for your build, whether that’s a simple strip foundation, trench fill, or a more complex raft design for challenging ground. Site preparation cost, including clearance, access arrangements, and any temporary works needed, is confirmed only after a proper site visit. This means your quote reflects the actual conditions on your property.
