Mastermix Joint-Loc mix is a kiln dried sand and cross-linked polymer blend designed to provide maximum bonding strength and durability. Typically joints between outdoor pavers are filled with sand, which tend to wash out over time. Our solution actually hardens with moisture creating a lasting bond which has been independently tested to maintain a 0.43KN shear strength with a 20mm gap.

Joint Loc is suitable for commercial and private use, including heavy traffic conditions, sloping sites and high wind areas. Further as it meets NZ Standards 3116:1991 for joint sand grading you can be confident our product will deliver the results you expect.
