Our infill sand products are combined with other materials to stabilize fields and cushion gameplay.
Our Infill Sand and Cork Sand are spread over synthetic turf fields along with a springy component, such as crumb-rubber pellets, cork, coconut husk, or wood. The infill mixture acts like a topsoil for athletic fields. When a new athletic field is installed, infill is spread onto the athletic field, filling the space between the synthetic grass fibers in order to support the fibers, stabilize the field, and cushion the playing surface.
Both infill sand products go through a rigorous wash cycle. Each product is kiln dried in our bagging and drying plant, then stored in silos after the drying process to cool down.
A typical field contains over 150–375 tons of infill.
Our permeable aggregates and E-Layer Stone help improve the performance and lifespan of synthetic turf fields.
Synthetic turf fields need to be replaced after 7–10 years, but a well-constructed base can last 3–4 times longer than the synthetic turf. Our permeable aggregates and E-Layer Stone have the qualities needed to create long-lasting foundations.
Underneath the synthetic grass, an elastic layer (E-layer) made up of rubber, stone, and epoxy binder boosts shock absorption and field drainage. E-layer manufacturers trust our E-layer stone to assist with these important functions.
A permeable aggregate base underneath the E-layer drains water from the field. Our permeable aggregates are made to spec and have been used up and down the coast to build field foundations.
Washington Rock also manufactures soil and top dressing sand for field construction and aeration.
Our Rootzone Mix is a made-to-order blend of sand and compost. We customize the specifications of the mix based on the architect’s or engineer’s requirements. We can also add the desired amount of organic additive, ranging from compost to peat moss, to achieve the correct end product.
Our USGA-grade top dressing sands can be used after aeration on existing fields, fairways, and greens. Top dressing sand promotes drainage, reduces thatch buildup, creates a smoother driving or putting surface, and encourages healthier grass growth.
