Chemical (Epoxy) vs. Mechanical Anchor
Mechanical anchors grip by expansion force; chemical anchors bond with adhesive. The right choice depends on the concrete and the load.
| Feature | Chemical Anchor | Wedge Anchor (Mechanical) |
|---|---|---|
| How it holds | Adhesive bond to the hole | Expansion wedge force |
| Cracked concrete | Works | Unreliable |
| Strength | Highest | High |
| Install time | Cure time required | Instant |
| Cost | Higher | Lower |
Verdict
Choose chemical anchors for maximum loads, cracked concrete, and edge-distance problems. Choose mechanical anchors for speed, cost, and simplicity.
