Overview
Bonded anchors transfer load through the bond between resin, rod and hole wall, so they do not create expansion stresses in the concrete. They suit small edge distances, post-installed rebar in slabs and beams, and equipment anchoring.
Capacity depends on hole cleaning (blow, brush, blow), embedment depth, temperature and curing time. Use products with a European Technical Assessment (ETA) or ACI 355.4 qualification and proof-test on site.
Uses
