Polymeric sand is a mixture of fine sand combined with other additives. When mixed with water, it forms a strong binding agent that can be used to fill spaces between pavers, tiles, and more. This type of sand is often used at the end of a landscape paving project with concrete, brick, or stone pavers.

Polymeric sand is a building material that fills and binds paving joints—spaces between units such as concrete pavers. It is officially described as a dry joint sand stabilizer.

Polymeric sand, or jointing sand, is a fine sand bound with polymers that is used to fill joints between pavers. It’s often swept into the joints and then sprayed with water, which activates the polymers and causes the sand to harden. This makes polymeric sand more durable and longer lasting than some alternatives.
