Lockblocks are a lightweight DIY alternative to conventional concrete blocks. Lockblocks are made with self-locating connectors, which enable the blocks to achieve a 2 mm adhesive joint when laid using Mason Bond. Typical uses include retaining walls, front fences, privacy dividing walls and landscape walls.
Mason Bond masonry adhesive is used instead of mortar to build masonry block walls. Mason Bond is simple to apply and sets quickly. Most masonry projects can be completed in half the time. Independent testing showed Mason Bond to be 3.5 times stronger than mortar and allowed 80% less water penetration.
