Rocla Duraspun® hollow spun piles are easier to handle and drive because of the high strength to weight ratio. This also allows a wider choice of rig and hammer sizes. The efficient mass-to-strength ratio allows longer length piles which can eliminate the need for jointing.
Because Rocla Duraspun® Concrete Piles are spun in accurately dimensioned steel moulds, they have a smooth dense finish.
The circular section eliminates misalignment and torsion stresses experienced with multi-sided piles. Rotation can be allowed to occur with no alignment or aesthetic problems.
The Rocla Duraspun® hollow spun pile can be confidently used in all ground conditions. These piles are designed to suit both driven and potted applications and various strength types and lengths are available.
