Polymeric sand is a precise mixture of natural Sand and polymer binders. This combination makes it perfect for filling in the joints of brick pavers or stones in patios and walkways.

Polymeric Sand or paver sand as it is sometimes called is a very fine grain sand that is combined with additives and, when mixed with water, forms a strong bond that helps lock pavers together.

Polymeric Sand is extremely popular here in Westchester and for a good reason. When used as it is intended with concrete pavers, brick pavers and stone pavers it helps limit and deter weed growth. Paver stones create the perfect environment for weeds and when polymeric Sand is used, weeds are effectively eliminated from the area.

  • Polymeric Sand improves the strength and durability of the pavers it holds.
  • The combination of the materials that make up polymeric Sand creates an incredible binding agent that locks the pavers together.

Polymeric Sand also completes the paver installation, ensuring you have a professional-looking driveway, walkway or patio for years to come.

Our team is standing by to answer any questions you have about polymeric sand its use or installation.

Is polymeric sand better than regular sand?

A loose-fill sand will wash away over time or when it is exposed to heavy rains. Because of this, polymeric sand for paver joints was developed to hold its form and to keep paver stones locked in place.

Is polymeric sand permanent?

Polymeric sand relies on a chemical reaction to harden it into the joints between your paving stones. Once it hardens, it is permanent.

Do weeds grow in polymeric sand?

Weeds can grow in the worst of conditions, including traditional paver joint sand. But because polymeric sand hardens and seals, it’s much more difficult for weeds to root in. As for insects, ants like patios for their loose dirt, making it good ground to colonize.


Client Testimonials
We care what our customers think of us and so should you.

I’ve used other power washing companies in Westchester and Westchester Wash and Seal is far and away not only my favorite power washing company to work with – but also the most talented and professional! Last summer they restored my deck which was covered in mildew, making it look better than it ever has, and they did it all with the best price I found! This year they power washed my Westchester home and walkways! Thanks for the great job Jim!
