What it is
A chemical (bonded) anchor is a steel rod set in a drilled hole filled with a two-part resin mortar. The mortar bonds to the rod and to the concrete along the full embedment, so the load is spread along the hole instead of being pushed into the concrete by an expanding sleeve.
Mortar types
| Chemistry | Strengths | Watch |
|---|---|---|
| Epoxy | Highest bond and creep resistance, long working time, rebar and seismic approvals | Slow cure in cold weather |
| Vinylester | Fast cure, wide temperature range, styrene-free versions | Shorter working time |
| Hybrid | Fast cure with high loads; base plates and rebar | Product-specific approvals |
| Polyester | Economical, light to medium loads, masonry | Not for cracked concrete or structural use |
Installation
Hole cleaning is the step that decides the capacity: dust left in the hole acts as a release layer. Follow the manufacturer's installation instructions for the approved product – drill type, cleaning tools, gel and cure times for the base temperature.

שאלות נפוצות
Can I load a chemical anchor straight away?
No – wait for the full cure time for the base temperature in the product table. Mechanical anchors are the choice where load is needed immediately.
