The waxed cardboard void former is placed over the bolt,and  stands on the plate washer. The cone is left in place whilst the surrounding concrete sets. This prevents ‘pull-out’ of the bolt whilst allowing for the lateral, circular movement of the bolt. Lining up of the above ground structure is therefore much easier. After the structure is fixed into position the void around the bolt can then be filled with grout.

We can also supply other types of void formers (sometimes known as bolt boxes). Please contact us to enquire about:
