Reducing Formwork Waste with Reusable Plastic Formwork

Formwork plywood is one of the most often replaced materials on a concrete job. Sheets swell, delaminate and lose their face after a handful of pours, then end up in the skip. Reusable plastic formwork sheets tackle that waste at the source: you buy, and throw away, far fewer sheets.

Where formwork waste comes from

Plywood usually lasts 3–8 uses. Water from wet concrete, rain and wash-down soaks into the veneers, the edges swell, and the face starts marking the concrete. Every worn sheet means another purchase, another delivery, more offcuts and another disposal cost.

How reusable plastic formwork reduces waste

• 50–100+ uses per sheet. One plastic sheet can do the work of many plywood sheets over its life.

• Waterproof, no swelling. Water is the main reason plywood fails, and it doesn't affect plastic sheets, so they keep their shape from pour to pour.

• Fewer deliveries. Replacing fewer sheets means fewer orders and less handling of new material.

• Less rework. A smooth, consistent face can reduce patching and rendering.

What it means for your costs

Waste and cost go together. Fewer replacement sheets can mean a saving of up to 70–80% on replacement costs compared with plywood. The exact figure depends on how many times you reuse each sheet and how well it's looked after.

Getting the most uses from each sheet

• Wash sheets with water and a brush after each pour.

• Inspect edges and faces before reuse, and set aside damaged sheets.

• Store sheets flat, dry and out of direct sun.

• Plan your cuts so offcuts can be reused on smaller elements.

Tracking it on your project

If you're working to a client's waste target, record how many pours you actually get from each sheet. Real reuse counts are the best evidence of the waste you've saved.
