Polymeric Sand Application

If you have an interlocking stone driveway, patio, or walkway, polymeric sand is one of the most important maintenance services you can invest in. Best Wash and Seal's professional polymeric sand application stabilizes your paver joints, prevents weed growth, and protects your interlock surface for years to come.

What Is Polymeric Sand? Polymeric sand is a specially formulated jointing sand that contains silica particles and a polymer binder. When activated with water, the binders harden the sand into a firm, flexible compound that locks your paver joints in place. Unlike regular sand — which washes out every season — polymeric sand stays in place and provides lasting joint stability.

Benefits of Polymeric Sand

Stops weeds — the hardened joint creates a barrier that prevents weeds from taking root between your pavers

Prevents ant infestation — ants love loose sand joints for nesting; polymeric sand eliminates this problem

Resists erosion — rain and water runoff won't wash polymeric sand out of joints like regular sand

Stabilizes pavers — keeps your interlocking stones from shifting, rocking, or becoming uneven

Enhances appearance — clean, uniform joints give your driveway or patio a finished, professional look

Protects edges — reduces the risk of edge pavers shifting or sinking over time
