Details

When a new layer of concrete or mortar is applied to the existing concrete to strengthen or repair a structure. A critical part of these situations is the transfer of internal stresses through connecting elements between new and existing concrete.

The ribbed or helical steel bolts are practical methods of connection resolution promoting the effective transfer of efforts between the two elements, existing and new.

The production and design of CORTARTEC bolts is adjusted to each situation of each project, being available in ribbed, smooth or threaded rod – in carbon steel with several anti-corrosion protections, painted, galvanized or coated with epoxy. Or in stainless steel of various alloys.
