Polymeric Sand Application
Our polymeric sand application service is the perfect finishing touch for your interlock driveway, patio, or walkway. We carefully sweep polymeric sand into the joints of your pavers, then activate it with water to create a strong, flexible bond that resists erosion, weed growth, and insect intrusion. The result is a clean, stabilized surface that maintains its structure and appearance over time.


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
