  Chemical Anchor Chemical Anchor: An Overview A chemical anchor is a fastening system that uses a resin-based adhesive to secure threaded rods, rebar, or bolts into various base materials, such as concrete, brick, and stone. Unlike mechanical anchors, which rely on expansion forces, chemical anchors create a strong, load-bearing bond through adhesion, making them ideal for high-load applications. How Chemical Anchors Work Chemical anchors consist of two main components: Resin & Hardener – Typically made of epoxy, polyester, or vinyl ester, these components mix to form a strong adhesive. Threaded Element – A rod, bolt, or rebar that is inserted into the drilled hole filled with the adhesive. Installation Steps: Drilling – A hole is drilled into the base material. Cleaning – Dust and debris are removed using a brush and air blower to ensure proper bonding. Injection of Resin – The adhesive is injected into the hole using a specialized dispenser. Insertion of ...
