Concrete spacers are made of heavy-duty concrete materials and are used for supporting large reinforcement both in vertical and horizontal applications which offer one, two, or three separate covers. They are a product designed for use in concrete construction containing joints, one side of which is subject to hydrostatic pressure. They are used as a barrier within the joint to prevent the passage of liquid through or across the joint. They are embedded in the concrete on both sides of the joint, and spans the joint, and are designed to deal with lateral and
transverse movements.
