Piling
Liniar's range of composite uPVC piling systems offers a sustainable method of retention for soil, banks, ponds and lakes, and is often used as a flood prevention barrier.
three decades in the making
Liniar has been manufacturing composite uPVC piling in Derbyshire since 1994. The sustainable choice for bank or water retention, Liniar piling contains recycled
the engineering solution of choice
With all types of composite piling providing huge benefits compared to steel piling, they are the engineering solution of choice across a wide number of companies including the National Trust, the Environment Agency, utility companies, landscapers and many international engineering firms. Liniar piling has even been driven to depths of 11.5m – read about the Bangkok project here.
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
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.
Liniar composite uPVC piling
Liniar's uPVC piling is a sustainable solution for soil and water retention projects across a wide range of applications. Easy to install and more cost-effective than steel piles, it won't corrode or rot and is easy to handle and transport.
Piling FAQs
Is composite piling more sustainable than steel piling?
Yes - not only is Liniar composite PVCu piling kinder to the environment as it won't rot or rust, it's made containing recycled uPVC material and can be fully recycled at the end of its useful life. As it's lighter than steel, Liniar piling can reduce the environmental impact of transport, as well as having the ability to be carried more easily to remote areas such as hills and mountains.
How is composite piling installed?
Liniar's piling can be installed in a number of ways - the most simple being by hand, using a rubber mallet to drive it into the ground. It has also been installed using a modified pile driver, as well as being driven to depths of 11.5m using an ingenious method of clamping it to a steel pile then releasing it once in the ground - read the case study here.
Can composite piling be used in sea water?
Yes - as Liniar composite piling is manufactured using window-grade, lead-free, recycled PVCu, it is unaffected by salt water, as well as being resistant to marine borer attack, so it's ideal for water retention projects around marine areas.
Are any accessories available for Liniar composite piling?
You can select 90 degree corner piles to enable piling to be installed around corners, as well as a piling cap to enable a driver to be used, allowing installation to greater depths.
Can composite piling be tied back for heavy duty use?
Yes, it can. The case study here demonstrates such a project, resulting in a delighted holiday park owner who used it to restore a large pond.
