Contiguous Piling in Taunton SW — Pile Walls for Excavation Retention

Contiguous piling is chosen where a retaining wall is needed for a basement, an excavation, or a retained cut, and where the ground is stable enough to stand between the piles. It suits basement conversions, commercial basements, and any project requiring ground retention.

Typical contiguous piling projects include domestic basement conversions, commercial basements, retained excavations, and any project requiring a pile wall to retain the surrounding ground.

Contiguous piling forms a wall by installing piles in a line, each one touching or nearly touching its neighbours. The resulting pile wall retains the surrounding ground, allowing an excavation — for a basement, underpin or retained cut — to be formed safely. Contiguous pile walls are typically used where the ground is stable enough to stand between the piles; where water retention is needed, a secant wall may be used instead.

We assess the ground and the retention requirements, then design the contiguous pile wall — pile diameter, spacing, depth and reinforcement. Our rig installs the piles in sequence to form the wall, and we coordinate the excavation with building control throughout.

Contiguous piling cost depends on the pile diameter, the wall length, the depth, the reinforcement, and the access. The retention requirements and ground conditions also affect cost. We provide a fixed quote within 48 hours of the site visit.

What is the difference between contiguous and secant piling?

Contiguous piles are installed with a small gap between them, and the ground between the piles must be stable enough to stand. Secant piles overlap, forming a continuous wall that can also retain water. Contiguous piling suits stable, dry ground; secant piling is used where water retention is needed.
