DynaMatrix® WJ Polymeric Jointing Sand is a dry mixture of calibrated sands, polymers, binders and dedicated chemical controlling agents specifically designed to bind firmly and easily together in horizontal pavement joints. It is specially made for use in wider joints and in high traffic areas. Applied dry into the pavement joints, it will harden and stay in place after being wet. Carefully blended with a higher content of polymers and dedicated control agents than any other comparable, the quality of DynaMatrix® WJ Polymeric Jointing Sand ensures increased stability, performance and lasting durability to your paver projects. Developed by a team of experts in chemistry and in the paver industry, DynaMatrix® WJ Polymeric Jointing Sand retains the adequate elasticity needed to adapt to the movements of the pavement surface. It will resist erosion due to weather, maintenance and traffic. For standard joints, we recommend you use DynaMatrix® RJ Polymeric Jointing Sand. For quick setting requirements, we recommend you use DynaMatrix® RJ X2 Polymeric Jointing Sand.
Product comes in a 22.7kg. (50 lb.) bag, which covers 2 to 8 square metres (20 to 80 square feet) depending on the width of your pavement joints.
