Contiguous pile walls consist of piles arranged in a line typically with a 150mm gap between the piles. Where required the soil between the piles can be stabilised using grouting techniques if necessary, either before or after pile installation. 

Common uses

Support of excavations
Slope stabilisation
Support wing walls

Process

Contiguous pile walls can be retained by anchors or strutting systems to reduce deflection though commonly for walls up to 7-8 metres in height they are designed to work in cantilever. 

Advantages

Limited load from surrounding structures taken
Allows easier work in open excavations when in cantilever

Quality assurance

We use the latest technology, testing regimes and best practice protocols developed over many years to ensure the position, verticality and structural integrity of our pile walls.
