ARXX Edge ICF blocks are assembled on site for the construction of walls a with concrete core from 4″ to 24″ or larger, providing maximum flexibility in design. The unique connectors snap into the web tees to connect the EPS panels together to assemble the form. The connectors each have grooves that are specifically designed to accommodate reinforcing steel placement. Because the forms are assembled on site, they require less space and save on the cost of shipping and storage. ARXX Edge ICFs are ideal for commercial projects, especially when the walls are high or very thick, or when building in remote locations. Download the ARXX Edge catalog.
