uPVC Piling – Box Format

Ideal product for projects that require a stronger and deeper solution – use Liniar Standard Pile in box format.

Why choose Liniar Standard Pile - Box Format?

We offer standard piling (a medium strength pile product) in a choice of two formats: box format and z-ribbed format.

By inserting every other pile the opposite way round the sheets are configured into a box format.

This configuration creates a much deeper profile with more strength.


Because of the additional strength of Liniar’s plastic standard pile when used in box format, it makes it an ideal product for projects that require a stronger and deeper solution.
