Plastic spacers and related products from recycled material for reinforced concrete construction

This EPD includes the following spacer types:

- Continuous spacers – normally characterised by elongated linear shape; used to support horizontal layers of reinforcement mesh

- Wheel spacers – normally characterised by a circular section, perpendicular to the bar to which it is attached; used for maintaining distance between vertical layers of reinforcement mesh and formwork

- Clip-on spacers – normally characterised by an integrated clip to clamp around the rebar; used with horizontal and vertical layers of reinforcement mesh

- Rebar chair spacers – normally characterised by cylindrical or rectangular shape with enlarged footing; used to support horizontal layers of reinforcement mesh or individual rebars

- Tunnel spacers – normally characterised by a tubular seat to hold the rebar and enlarged footing; used to maintain the distance between reinforcement and sealing on the uphill side of a tunnel

- Tube spacers – normally characterised by a constant hollow cross section; used to maintain the distance between formwork faces; allows tie-rods to be inserted and withdrawn for re-use
