Why choose Liniar Trench Pile?

The use of Liniar’s plastic piling provides a low cost alternative to steel piling in many situations that require temporary shoring during the civil engineering construction of bridges, tunnels, drainage systems, manholes and a whole host of other uses.

Liniar’s trench sheet pile is designed as a shuttering for temporary or permanent ground works in the utility sector.

The unique corrugated design provides additional strength and it is much lighter and easier to handle than steel and therefore cheaper to transport, and the risk of sparking is eliminated because it’s made from uPVC – making it the ideal choice for temporary shoring.

Applications

The primary use Liniar’s trench sheet pile is for temporary shoring, ground support and trench work. It’s ideal to be used by ground workers and utilities to provide a safe working environment in various excavations.
