/ Our Services
Our Foundation Services
We specialise in all UK-recognised foundation systems, including:
Strip Foundations
Ideal for smaller buildings and extensions with good ground bearing capacity. These consist of continuous strips of concrete beneath load-bearing walls.
Trench Fill Foundations
A quicker, concrete-heavy solution where deep trenches are backfilled entirely with concrete. Great for cohesive soils and time-sensitive projects.
Raft Foundations
Suited to weaker soils or where differential settlement is a concern. Rafts distribute load across the entire footprint of the building.
Pad Foundations
Used where structural loads are concentrated in points — such as steel columns or posts. Pads are isolated concrete blocks positioned strategically beneath the building.
Pile Foundations
- Ideal for poor soil conditions, restricted access, or larger loads. We offer driven, bored or screw pile systems depending on your project’s needs.
- We help you select the right foundation type based on:
- Soil investigation or percolation results
- Building size and load distribution
- Nearby structures and environmental risks
- Access and space constraints
