What does "chemical anchoring" refer to in bolting applications?

In bolting applications, "chemical anchoring" specifically refers to the process of using a resin or epoxy to bond bolts to concrete or other substrates. This method enhances the stability and strength of the attachment by creating a strong chemical bond that can significantly increase load-bearing capacity compared to traditional mechanical anchors. The resin penetrates the concrete, providing a durable and robust anchorage for the bolt.

This technique is particularly advantageous in environments where mechanical anchoring methods may fail due to factors like vibration, temperature fluctuations, or the porosity of the material. Chemical anchoring effectively fills voids and weaknesses in the substrate, which not only secures the bolt but also offers resistance to various external forces.
