Plastic Lockjoint is a lightweight yet sturdy PVC jointing solution to create a keyed contraction joint. Lockjoint’s unique shape ‘keys’ two slabs together, allowing for movement without lifting or dropping of either slab. It is finished off with a clean rubber strip on top for a neat and classy finish to the concrete joint.
