ProSolve Concrete Line Spacer 50mm x 50mm x 1m

A reinforced spacer bar (also known as concrete mars bars or chocolate blocks), made of extruded fibre concrete, for use as a reinforcement bar spacer.

They are designed to effectively provide stability for rebar mesh and rebar rods in heavy-duty loading. They have high compressive strength and are also chemical resistant. They bond well with concrete, producing no hairline cracks after application.

We recommend that they are spaced every half square meter.
