Concrete Accessories Information

Concrete Accessories are anchors, inserts and expansion and contraction joints used in concrete forming.

Concrete anchors are used to fasten just about anything into concrete. Anchor types include epoxy, mechanical fasteners, expansion anchors, heavy-duty shields and light duty anchors.

Concrete inserts are devices that can include pipe sleeves, threaded bolts and nailing blocks. They are attached to concrete forms in such a way that after the concrete is placed and the forms are removed, the inserts remain embedded in the concrete.

Expansion joints allow for thermal expansion and contraction in concrete, as well as for shrinkage and structural movement. Expansion joints are normally formed by the incorporation of a compressible material, such as a closed-cell plastic foam or board.

Essentially, contraction joints, also known as control joints, are purposefully placed, even "cracks" in concrete that are designed to prevent the unsightly, unplanned cracks that occur over time as concrete structures dry out and shrink. Contraction joints accommodate certain types of structural movement, as well as normal concrete shrinkage due to changes in temperature from maximum to ambient. They can be created by use of a hand groover, by sawing after the concrete is sufficiently hard, or by inserting strips of plastic, wood, metal, or preformed joint material into the unhardened concrete.
