A layer between concrete and substrate to prevent direct bonding, accommodating movement and reducing crack risk.
A Cleavage Membrane is a layer of material placed between a concrete slab and a substrate to prevent direct bonding between them. It is used to accommodate differential movement or settling of the underlying layers, thereby reducing the risk of cracks or damage in the concrete. Typically made from materials such as polyethylene or fiber-reinforced paper, the cleavage membrane ensures that the concrete slab remains stable and performs effectively.
