Anchor installation into hardened concrete

Installing all-thread or rebar dowels into hardened concrete using epoxy is a common method for creating strong connections between new and existing concrete structures. The process involves drilling holes into the hardened concrete where the dowels will be installed, cleaning the holes, and then filling them with an epoxy adhesive. The all-thread or rebar dowels are then inserted into the epoxy-filled holes and allowed to cure, creating a strong and durable connection. Here are the steps involved in the process of installing all-thread or rebar dowels into hardened concrete using epoxy:

1. Drill holes into the hardened concrete at the locations where the dowels will be installed. The diameter and depth of the holes should be in accordance with the design specifications. 2. Clean the holes using compressed air or a vacuum and a wire brush to remove all dust, debris, and loose material. The clean holes ensure proper adhesion of the epoxy to the concrete and the dowels. 3. Install the epoxy adhesive into the holes, following the manufacturer's instructions for mixing and application. The epoxy should be poured into the hole until it is about half full. 4. Insert the all-thread or rebar dowels into the epoxy-filled holes, making sure they are properly aligned and inserted to the required depth. Rotate the dowels during insertion to ensure that the epoxy adhesive is evenly distributed around the dowel. 5. Allow the epoxy to cure for the required time, usually several hours to a full day, depending on the specific product used and the ambient temperature and humidity.

Once the epoxy has cured, the all-thread or rebar dowels will be securely anchored into the hardened concrete, creating a strong and durable connection that can resist the forces of tension and compression. This method of installation is commonly used in structural concrete applications, such as connecting new concrete to existing concrete or reinforcing concrete columns and walls. It is a reliable and effective way to create a strong and long-lasting connection between concrete structures.
