Steel cased piles→

How it works

A steel casing is driven into the ground with a compact drop hammer or ground-displacement rig until it reaches the required resistance. The casing is then reinforced and filled with concrete to form the finished pile. Casings can be cut down or extended on site, so the pile length follows the ground rather than a guess made in advance.

Our steel cased rigs are small and light, so they work where larger driven rigs can’t, including restricted access sites where removing spoil would be difficult and costly.

When it’s used

Steel cased driven piles are typically considered for made ground, sands and gravels, contaminated ground and ground with a high water table, on schemes with lighter loads.

Advantages

• A straightforward, cost-effective solution for lighter loads
• Flexible: piles are easily cut or lengthened, and casings come in any length and a wide range of diameters
• No arisings, so no spoil disposal costs and minimal waste
• Displacement piles are the preferred option in contaminated ground
• Useful on restricted access sites where removing spoil is difficult and costly
