Groundworks & Foundations Northampton

Groundworks and foundations don't get seen once a project is finished, but they determine whether everything built on top of them stays sound for decades or develops problems within a few years. We carry out groundworks and foundation work across Northampton and Milton Keynes, as part of extensions, garden rooms and other building projects.

Groundworks Services

  • Excavation and site clearance ahead of a build

  • Foundation design and construction suited to the ground conditions and structure being built, whether that's traditional strip foundations, trench fill, or piled foundations for more challenging ground

  • Drainage installation, including surface water and foul drainage connections

  • Groundworks for driveways, patios and other external structures, covered in more detail on our driveway and patio installation page

Why Ground Conditions Matter

The right foundation type and depth depends heavily on the specific ground conditions of the site, soil type, groundwater levels, the presence of tree roots nearby (which can affect clay soils in particular), and any previous ground disturbance. Getting this wrong is one of the more expensive mistakes to fix after the fact, since it can mean the difference between a stable structure and one that develops cracking or movement over time. Larger or more complex projects typically involve a soil survey and, often, a structural engineer's input to confirm the right approach.

Note

Building Regulations for Foundations

Foundation work for extensions and new structures falls under Building Regulations, and building control will typically inspect foundations before they're covered over, since this is the point at which problems are easiest to identify and correct. We manage this inspection process as part of the project.

Why Choose Bridgework

  • Proper assessment of ground conditions before committing to a foundation design

  • Coordination with structural engineers where a project needs that input

  • Building Regulations inspections managed as part of the project

  • A clear quote before work starts

Groundworks FAQs

Not always, but it's common practice for larger or more complex projects, or where ground conditions are uncertain, since it helps confirm the right foundation type and avoid costly surprises during construction.

This varies by ground conditions, structure and local factors such as nearby trees, and is confirmed by a structural engineer or building control based on a site-specific assessment rather than a generic figure.

Yes, this is a standard part of the Building Regulations process, and we manage the necessary inspections and notifications as part of the project.

Yes, particularly on clay soils, where tree roots can affect ground moisture levels and, in turn, foundation design. This is something a soil survey or structural engineer would typically assess for a specific site.
