Fields all over the Pacific Northwest use Washington Rock’s topsoils and infill sand.
Our infill sand is combined with other materials to stabilize fields and cushion gameplay.
Our infill sand is typically spread over fields along with a springy component, such as crumb-rubber pellets, coconut husk, or cork. 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.
A typical field contains over 150–375 tons of infill mixed with other materials.
Our infill sand is clean and bone dry.
Our infill sand goes through a rigorous wash cycle and is then kiln dried in our bagging and drying plant.
Our infield mix is a proprietary sand, silt, and clay mix used around baseball diamonds. We have a standard mix on hand, but we can design a mix to the architect’s or engineer’s requirements. We can add in amendments to any mix as well, ranging from Turface to Axis—the sky is the limit.
Our rootzone mix is a custom blend of sand and organic materials. We can also customize the specifications of the mix based on the architect’s or engineer’s requirements. We have a large variety of sands to choose from. We can also add the desired amount of organic additive, ranging from compost to peat moss, to achieve the correct end product. These mixes are made to order for each individual customer or project.
