Cover Block Rubber Mould

A cover block is essentially a spacer that is used to lift the rebar matrix off the ground so that concrete may flow underneath the rebar. In order to prevent corrosion of the rebar, it needs to be fully encased in concrete. By code, it usually needs about 2 to 3 inches of coverage on all sides.Block casting molds are designed to pour a large cavity which allows a user to create casts that can be cut into multiple pen blanks from mixed color resins (dirty pour flip cup or swirls), embedding inorganic shredded materials such as US currency or color pencils, or organic materials such as coffee bean.
