The scope of foundation contractor varies by site, but the objective is consistent: reduce ambiguity, choose a practical method, and deliver a result that holds up under real operating conditions.

We deliver foundation packages for developers, housebuilders and main contractors — strip, pad, raft and piled foundations built to structural design with setting-out, reinforcement, concrete placement and handover records. Work is coordinated with ground investigation, piling and enabling works so substructure stays on programme.

Enquiries usually arrive when stakeholders need a clear route from symptoms or requirements through to implementation, without avoidable rework.

How we work with clients

On new-build schemes, foundations are often delivered with piling contractors or concrete foundations. For developer-led packages see groundworks for developers; for investigation first see ground investigation services.

For package pricing and tender returns, see our tender enquiries page. Specialist subcontractors can register via our contractor network.

Larger construction projects may require a topographical or utility survey before groundworks begin.

How the service works

We follow a structured approach from site assessment and design coordination through to setting out, excavation, piling and foundations, drainage and services, and reinstatement and handover. Each phase is planned and delivered to programme.

    What this step delivers: The right method, sequence, and dependencies are agreed for predictable delivery.

  2. Step 2: Setting out and excavation

    What this step delivers: This stage improves certainty and reduces avoidable rework.

  3. Step 3: Reinforcement and concrete placement

    What this step delivers: This stage improves certainty and reduces avoidable rework.

  4. Step 4: Curing, protection and testing

    What this step delivers: Completion is validated and handed over with clear next steps.

  5. Step 5: As-built handover

Our approach focuses on selecting the right method based on site conditions and project requirements, then documenting each stage so decisions stay clear throughout delivery.

Frequently Asked Questions

What foundation types do you deliver on commercial schemes?

Strip, pad, raft and piled foundations to structural design — coordinated with ground investigation and piling so bearing and settlement assumptions match the built solution.

Do you work to engineer-issued drawings only?

Yes. We build to issued foundation details and reinforcement schedules; design changes are managed through your engineer with RFIs tracked on site.

Can foundations be phased with plot release?

Yes. We plan pours and inspections around developer or housebuilder phase handovers so follow-on trades are not waiting on substructure.

What QA records are provided?

Cube tests, reinforcement inspections and as-built levels are recorded for building control, warranty providers or client QA folders.

What practical factors should be reviewed first?

Review ground conditions, logistics, and dependencies with other construction packages early to keep scope realistic and avoid unnecessary rework.
