Another key advantage of using resin anchors for concrete is their ease of installation. Unlike traditional anchors that require drilling, tapping, or welding, resin anchors can be easily applied using a simple, straightforward process. First, the anchor hole is drilled into the concrete surface, then the resin adhesive is injected into the hole using a specialized dispenser. Once the resin is cured, the fixture can be securely attached to the concrete surface.
