Chemical Anchors

Chemical anchors are fastening systems used in building construction that uses chemical resin compounds to secure bolts, rods, or threaded bars in concrete, masonry, or timber structure. Chemical anchors are distinct from expansion and friction-type mechanical anchors since they distribute the load across the entire embedment area, thus creating a strong bond that resists intense tension, compression, and vibration forces.
The anchoring system typically has two components: a chemical resin (like epoxy, polyester, or vinylester) and a hardener. When mixed, they create a fast-setting, high-strength adhesive that seals joints between the base material and the fastener.

Canterbury Timber chemical anchor solutions deliver increased holding power, excellent water resistance, corrosion-resistant solutions, and can be installed near timber edges without splitting the wood. Our chemical anchor bolts feature optimized thread designs for better adhesion, and our chemical anchor rods offer maximum area of bonding with precision threading patterns, making them well-suited to timber frame construction, bridge building, and safety-critical applications in high-humidity conditions.
