PRODUCT INFORMATION & RESOURCES

DESCRIPTION

CEMIX JOINT SAND is a scientific formulation of graded sand to allow flexible filling of vertical joints in segmental paving. It forms a flexible joint allowing slight movement of the pavers. It is prepared in a fully computerized environment, where a high degree of accuracy and consistency is maintained.

TYPICAL APPLICATIONS & USES

  • Joint filling and base preparation for pavers, clay tiles and cobbles
  • Any type of paving joint that is not in a high wind and high trafficked area

ADVANTAGES

Computerized for a high level of accuracy and consistency

 

SUBSTRATE PREPARATION

Ensure joints between pavers are free of any contaminants such as soil, vegetation, pooling water, etc.

APPLICATION

After laying the paving, clean and dry the substrate. Do not apply CEMIX JOINT SAND to damp pavers. Spread the contents of the bag directly onto the pavers, and use a stiff broom to sweep the contents into the joints. Any product left over the pavers, should be swept clean and then work the entire area with a vibrating plate compactor for a minimum of two passes. Due to the vibration, the CEMIX JOINT SAND will settle in the joints and some more CEMIX JOINT SAND might need to be poured over and broomed in to fill those gaps. Compact the entire area again. Apply a light even spray of clean water. For large scale commercial applications, please get in touch with the supplier or Cemix for advice.

MATERIALS

CEMIX JOINT SAND consists of a uniformly blended, properly proportioned mixture of sands and other additives to improve workability and performance of the product.
