FAQ’s Recycled Plastic Wood products

Recycled Plastic Wood - Versatile, Sustainable, Durable

Our recycled plastic wood products are made from a variety of recycled plastics, including HDPE, LDPE, and PP. We use a special manufacturing process to create a wood-like product that is strong, durable, and environmentally friendly.

Our products are perfect for a variety of outdoor applications, including decking, fencing, cladding, and more. They are also rot-resistant, insect-resistant, and UV-resistant, making them a great choice for long-term use.

About Us

What material is Filcris’s Recycled Plastic Wood made from?
Nearly all the recycled plastic supplied by Filcris Ltd is High-Density Polyethylene (HDPE). The only exception is Stokbord, which is Low-Density Polyethylene (LDPE) and the mixed plastic used in the Ecohoarding sheet.
Why is Polyethylene ideal for Recycled Plastic Wood?
Polyethylene is ideal for use in exterior, and especially wet or underground applications because it is:

  • Tough and durable
  • High impact strength
  • Resistant to degradation by most acids and rot
  • Maintenance free
  • Chemically inert
  • Flexible, with a high degree of expansion and contraction in warm or cold weather
Why choose recycled plastic wood?
  • Durable and long-lasting: Recycled plastic timber is rot-resistant, insect-resistant, and UV-resistant, making it a durable and long-lasting choice for outdoor applications.
  • Low-maintenance: Recycled plastic wood requires very little maintenance, making it a cost-effective choice in the long run.
  • Attractive and versatile: Recycled plastic wood looks and feels like real wood, but it is more durable and requires less maintenance. It is also a versatile material that can be used for a variety of applications.
  • Sustainably created: Recycled plastic wood is made from recycled plastics, which helps to reduce waste and conserve natural resources.
How easy is it to install Filcris products?

Installing the lawn or path edging material is very simple – simply treat it in the same way as timber edging.

There are 2 main ways of using the edging boards:

Flush – This is level with the ground surface and/or path. This is the standard way of using the edging boards, allowing grass to be cut without the boards impeding the blades, and reducing trip hazards. Since the material is held in position by the soil and the path surface it is butting up against, fewer stakes may be needed.


Raised – This is useful where beds and borders are being edged, to prevent soil and mulches from spilling onto the lawn, patio or decking. The edge can be sunk partially into the ground to adjust the depth and to get a more secure fixing. It should be held in position with stakes – we supply a wide range of sizes for different applications. You will find that more stakes will be required for this type of edging.

What type of planks should be used?
This will depend on the type of project being undertaken:

  • Raised Edging: Rigid Edging Plank
  • Raised Edging with Extra Stakes: Flexible Edging Plank
  • Flush Edging, very straight edges: Rigid Edging Plank
  • Flush Edging, gentle curves: Rigid Edging Plank, Flexible Edging Plank
  • Flush Edging, tight curves: Flexible Edging Plank
What type of stakes should be used?
  • Flush & raised edging into solid ground: 40mm x 40mm x 300mm, 40mm x 40mm x 450mm, 50mm x 50mm x 300mm
  • Flush & raised Edging in to looser soil: 40mm x 40mm x 450mm, 40mm x 40mm x 600mm, 50mm x 50mm x 600mm
  • Tight curves or free ends: 40mm x 40mm x 450mm, 40mm x 40mm x 600mm, 50mm x 50mm x 600mm
  • Of course, other types of stakes can be used, although if timber stakes are used there is a risk that they will rot and if the edge is of the raised type it may fail. With flush-type edging, this is less of an issue since the edging planks are supported by the soil and path material.
How many stakes are needed?

It depends on what type of edging board is being used, how the edging is being installed, what shape is desired and how high you want it. On average we would recommend the following spacing:

  • 18mm x 140mm: Flush: 750mm Raised: 500mm
  • 25mm x 150mm: Flush: 1000mm Raised: 750mm


Bear in mind:

  • If the edging is to be used as a raised edge we would recommend 1 per 500mm for 18mm thick boards and 1 per 750 mm for 25mm thick boards.
  • If the edging is curved you may need fewer stakes. On a gentle curve, it will not be very different
  • But on a very tight circle the strength of the curve can hold the circle in position. See the image below (“Curves held in position with few stakes”) shows a raised bed made from 18mm x 140mm planks with only 5 stakes.

How do I work with the recycled plastic wood?
Recycled plastic wood can be cut with a handsaw in the same way as timber. Fixing the planks onto the stakes is best achieved with screws (simple wood screws will work, we tend to use Spax or Turbo Ultra type screws which can self-countersink). If screwing, we advise that a pilot hole will be needed. The material cannot be glued – it is Polyethylene which does not bond well to any glues.
Does the material warp or bend?
Recycled plastic does not warp when it gets wet, but it does expand and contract with temperature changes. An expansion gap of about 5-10mm between the ends of planks will accommodate this movement.
Can the material just be pushed straight in?

It can be knocked in with a rubber mallet, although making a slot with an edging spade will make it easier. However, we recommend that you make a shallow trench and backfill to the plank.

Why don’t you make it easier for the edging board to be pushed straight in?
To get the best of the strength benefits of recycled plastic wood it has to be a reasonable thickness. Thinner non-recycled plastic products that can be pushed straight in are available but they do not have either the strength or the durability of our recycled plastic wood products, and when they break you will have to add to the waste mountain rather than take away from it!
