Log pile

Liniar’s unique log pile was designed for locations where a more natural appearance is required and replicates a wooden log effect. Interlocking tubes slot together to form a retaining structure and the external surface is covered with a timber composite finish, giving it a natural look and enabling algae or moss to grow. The colour will evolve over 6-8 weeks before settling to its final state.

Full pan pile

Ideal for bank retention and restoration for riverbanks, streams, ponds, lakes and reservoirs, as well as fish farm bank reinforcement, inland marina and waterway walls and banks. It will perform superbly well in any bank retention location and is also used for trench shoring - due to the lower cost of composite uPVC piling as opposed to steel, Liniar’s full pan pile can be left in situ in the trench after work has been completed.

Standard Pile Z Ribbed

Standard pile – Z-ribbed

Similar in appearance to some steel sheet piles, standard piles installed in a Z-ribbed format have a shallow front-on profile and cover slightly more ground than in the box format. This style of uPVC piling is predominantly used in retaining and floodwall applications where bending strength governs the design and no deflection or swing between sheets is required.

Standard pile – box format

Creating a deeper profile with much greater strength, installing Liniar composite standard piling in box format means it’s ideal for projects that require high levels of strength and depth. Used for larger expanses of water or higher banks, box format piling provides the ideal solution for heavy-duty applications.
