Why choose Liniar plastic piling?

Liniar began manufacturing plastic piling in 1994 in Derbyshire and has constantly and consistently increased its share of the market as more customers become aware of the benefits.

Liniar is part of the Flamstead Group of companies and has more than 40 years of experience in the plastic extrusion industry.

Plastic piling is available ex-stock from Liniar in a variety of lengths and is manufactured in Liniar’s own state-of-the-art factory in the heart of the UK. Our extrusion facility in Derbyshire boasts the largest mixing plant in Europe and continued investment keeps Liniar at the forefront of innovation.

We offer a versatile range of piling systems, including the traditional standard pile shape that can be configured as ‘Z-ribbed’ (for light use) or ‘box’ (for heavier use), and the facility for tying back and creating 90° corners.

Scale models of plastic piling are available on request – and by coming direct to the manufacturer, you can rest assured we can respond to requests quickly and efficiently.

Liniar has the capability to manufacture plastic piling in a wide range of lengths, direct from our UK factory.

The plastic piling is generally produced in grey from 100% recycled uPVC materials, but it can also be made in a variety of colours to suit individual requirements (subject to minimum order quantities) and offers a cost effective alternative to the more traditional steel, timber or concrete piling. Colour will evolve naturally over 6-8 weeks before setting to it’s final state. This can be treated with a water-based stain.

We manufacture a wide range of piling styles dependent on strength, ease of installation and type of appearance required.

These include Standard Pile, Full Pan Pile and Log Pile.

Plastic piling can be installed by mechanical or manual installation.

In many situations, particularly when short lengths of plastic piling are being installed, it can be inserted into the ground using a maul and pile cap. This is often the case in peat land areas, where the ground conditions are more favourable.

When installing longer lengths, or where the ground conditions are more difficult, a piling hammer should be used. The Liniar team can help you choose the most suitable type dependent on the application, and refer you to an appropriate rental supplier.

Liniar’s plastic piling is extremely versatile and can be used in a number of applications across different industry sectors:

  • Riverbank, stream, pond, lake and reservoir bank retention and restoration
  • Fishing lake and fish farm bank reinforcement
  • Inland marina and waterway walls and banks
  • Creating well defined drainage culverts and channels for agricultural land and house/urban development
  • Blocking of ditches on peat bogs and other nature reserve situations
  • General bank retention
  • Trench shoring
  • Permanent shuttering/land remediation cut-off walls
  • Highway applications
  • Non-piling applications, including soil boxes, railway ballast retention and compost containers

One of the most popular uses for plastic piling is to stabilise slopes by the side of highways. The Transport Research Laboratory (TRL) conducted major research into the use of plastic piling and published a report into their findings – Guidance on the Structural Use of Plastic Sheet Piling in Highway Applications (ref: TRL 533). A copy of this research is available here.
