The Best Uses For Epoxy Anchor Bolts

Working with set concrete, particularly to attach wooden walls or other types of structures, can be extremely difficult. There are different types of concrete bolts that can be used, including specialized concrete anchors that are relatively easy to install and then wedge into the hole to create a durable and lasting attachment point.

There is also the option to use epoxy anchor bolts in these types of situations. Many engineers opt to use the epoxy and bolt combination to hold wooden studs to concrete as the bolts can be longer and anchored further into the concrete that is possible with standard wedge bolts.

In addition, different diameters of epoxy anchor bolts, particularly those of larger diameter, are easier to work with due to the simple installation process. Cracking or chipping of concrete is also not a concern, but it can be with a shallower wedge anchor bolt choice.

How To Install

All types and sizes of epoxy anchor bolts are really two different components, a straight rod, and the epoxy. A hole is drilled into the concrete and cleaned out, typically using a shot of compressed air to remove all dust, chips, and debris from the drilling.

The depth of the hole can be easily controlled by an indicator on the drill for consistency, which will be important for stability and security of the fastener. Then, the epoxy is either injected into the hole or applied to the all-thread or rod section and inserted into the hole.

The epoxy is then allowed to dry and set into the hole for at least 24 hours. After the epoxy is dry, it has fused to the sides of the concrete hole, securing the rod. The wooden stud is then drilled to match the rod location, and a washer and nut are used to tighten and secure the stud to the concrete surface.
