Bolt Boxes - Expamet

Product Code Wire Mesh Sleeves
Expanded Metal Sleeves, Void Formers...


When installing foundation bolting, specifically SSOX, instances arise where a pocket or void is required around the bolt, to allow for easier adjustment even after the concrete has been poured and set.

The former is simply placed over the inverted bolt, fitting flush with the plate washer or anchorage. The formers can be left in situ until the concrete has set or in the later stages of the concrete setting when the former can be rotated*, breaking the bond with the concrete and removed allowing for grouting around the anchor after setting the bolts in their final position.

We offer three alternative products for this purpose in Polystyrene Tapered Cones, Hollow Waxed Card Cones, cylindrical 'Expamet' wire mesh sleeves.
