When new steel needs to connect to existing concrete — for an extension, a retrofit or a repair — the connection has to be as strong as the structure itself. Epoxy anchoring is the method engineers rely on to achieve that.
What Is Epoxy Anchoring?
Epoxy anchoring, also called chemical anchoring, is a method of fixing rebar, threaded bolts or studs into hardened concrete using a high-strength structural epoxy. A hole is drilled, cleaned and filled with epoxy, and the steel is inserted. Once cured, the epoxy bonds the steel to the concrete with very high load capacity.
Why Use Epoxy Anchoring?
Mechanical anchors rely on expansion pressure and can be unreliable near edges or in cracked concrete. Epoxy anchoring transfers load through a continuous bond along the full embedment, which gives higher capacity and better performance in demanding conditions.
Key Benefits of Epoxy Anchoring
- High load capacity — strong, dependable connections
- Performs in difficult concrete — works near edges and in cracked zones
- Suitable for rebar and bolts — ideal for post-installed reinforcement
- Vibration and seismic resistant — maintains grip under dynamic loads
- Fast curing — quick turnaround for site programmes
Where Epoxy Anchoring Is Used
Epoxy anchoring is essential for building extensions, post-installed rebar connections, structural strengthening, fixing steel sections and brackets, machine bases and façade fixings.
Why Hole Preparation Is Critical
The single biggest factor in anchor strength is a clean hole. Dust left in the hole prevents the epoxy bonding to the concrete. Proper drilling, brushing and blowing out the hole is essential — and it is a step our team never skips.
