Best Sand for Paver Joints

What is the best sand for paver joints?

This is a great question to ask because you want to maintain the durability and longevity of your newly installed pavers. Polymeric sand is a high-tech mix of graded sand and binders, 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 locks in place and remains stable. It softens when wet and firms up when dry to better resist soil movements.


Polymeric sand is the ideal choice for filling in the joint spaces between your pavers because it offers many advantages such as,

#1 Secures Pavers: Polymeric sand keeps your pavers locked in place while also remaining flexible. The composition of polymeric sand includes both a high-tech mixture of graded sands and polymer which allows it to remain solid and bonded but flexible enough to move during freeze/thaw cycles without shifting the pavers out of place.

#2 Weather Resistant: Polymeric sand can withstand high levels of moisture. Other traditional sand used for jointing cannot and will wash right out of the paver joints thus causing the pavers to pull apart. Polymeric sand solves this common issue because it is waterproof and is flexible enough to withstand the expansion and contraction that occurs with the change in seasons. This increases the longevity of your pavers and provides easy maintenance.

#3 Helps Prevent Weeds & Pests: Polymeric sand that is used to fill the joints prevents plant life from growing up in between the stones. In addition it helps prevent weeds from growing that are airborne because the seed cannot root itself into the solid composition of the sand.The sand also prevents ants from coming up between pavers and building nests.
