What is Polymeric Jointing Sand?
TECHNISEAL Polymeric Jointing Sand is a high-tech mix of graded sand (ASTM C-144) and binder, specially formulated for the filling of narrow or wide joints when installing pavers, slabs or natural stones, or when replacing existing joints. Unlike conventional sand, it stays in place and remains stable. It softens when wet and firms up when dry to better resist soil movements.
