Where are adhesive anchoring connections on civil jobsites?Īlthough adhesive anchor connections are most frequently associated with building projects, they can be found on jobsites in every infrastructure discipline. Accessories include the ancillary tools to properly drill and prepare the hole, mix the adhesive to the appropriate ratio, and inject the adhesive completely without air voids. Anchor elements range from threaded rod and rebar to proprietary or specialty inserts that offer benefits like additional strength, zero cleaning, or temporary attachment.

The adhesive may be either injectable or in capsule form this article will focus on injectable adhesives. Adhesive anchors transfer load placed on the anchor element to the base material through bond strength. In comparison to post-installed mechanical anchors, adhesive anchor systems generally offer greater performance, more flexibility in edge and anchor spacing, and more versatility when compatible with various anchor elements. In several applications, post-installed connections may be favorable to cast-in where jobsite processes are hindered, or safety risks are posed by cast-in elements extending out of the concrete surfaces.

Adhesive anchor systems are often utilized in conditions where cast-in anchors are missing, misaligned or damaged, or for retrofit projects into existing structures. An adhesive anchor system is a type of post-installed fastening for attachment of metal to concrete or masonry base material, or new concrete to existing concrete.
