STALOK PAVER SAND is the only porous polymeric joint sand available. Polymeric sand is a category of joint sand that after swept into the joints is activated by water. It sets-up firmly, inhibits weed growth, insect penetration, and erosion. Stalok Paver Sand is unigue as it captures vital rainfall and recharges the ground water supply. The sand also manages run-off and performs under constant vehicular, pedestrian, and maintenance traffic.
COMPOSITION: Stalok Paver Sand is comprised of dry, washed, quartz sand with a variety of particle sizes, combined with a non-toxic binder. The binder is a proprietary blend of two individual binders. The first is a natural binder derived from a crushed seed hull. The second is a polymeric binder derived from a mineral oil that coast the crushed seed hull. This combination is blended thoroughly into the sand, so the appearance of Stalok Paver Sand is like that of normal sand prior to installation. The combination of binders gives the Stalok Paver Sand both the flexibility of naturally stabilized joint sand and the strength of polymeric joint sand.
HOW IT WORKS: The binder works its way tino the pore spaces between the different sizes of sand particles. Once activated by water the binder swells up and binds the sand particles together, hardening after it dries. Since Stalok Paver Sand works from the pore spaces within the sand; it is easier to deal with when a little is left on the surface of the paver. Other polymeric binders essentially glue the sand in place, so they are difficult to remove when mistakes are made.
WHAT TO EXPECT: if installed properly the Stalok Paver Sand will remain consistently strong like concrete, yet still flexible. When dry, Stalok Paver Sand can be power washed and still remain in place. When wet, the Stalok Paver Sand acts like a sponge; it soaks up water until it is fully saturated, after saturation it allows the water to drain. During this process the Stalok Paver Sand will soften slightly, but will not move from between the pavers. After drying, the Stalok Paver Sand will return to its firm state without cracking. If any imperfections arise, simply sweep more Stalok Paver Sand into the joint on top of the existing Stalok Paver Sand and wet. It works with all climatic conditions and freeze/thaw cycles. Stalok Paver Sand can be used with any paver or edging materials.
DRAINAGE: Results may vary. Usually 5 inches of water will percolate through 1 square foot of Stalok Paver Sand every hour. The total drainage of the paved area depends on the percentage of the area that is comprised of joint space. For instance if a patio is 10 square feet and is comprised of 10% joint space, then the entire patio will drain 5 inches of water per hour. Remember the Stalok Paver Sand will shed water until it becomes saturated.
