Specialty Sand & Gravel


Septic Sand

N.J.A.C. 7:9A – Our septic sands meet the criteria set forth in the New Jersey Administrative Code – Standards for Individual Subsurface Sewage Disposal Systems. Our Septic sand has been used in Southern New Jersey for years and it is the gold standard for performance.

Infield Mix

Due to Whibco’s vast reserves, we have the ability to produce many different grades of Infield mix. Our blends of infield mix range anywhere from 8% clay content to 20 % clay content. Our infield mixes have been used at Little League, High School, college, and professional baseball or softball fields.

Equestrian Sand

Whibco produces many different types of equestrian footing materials. For Dressage style of riding we produce very fine silica sand that is rolled to form a base that feels as hard as concrete to you and I, but to a horse, it has the right amount of give and sponginess. For Western style riding the footing material has clay and silt which allow the material to compact while adding cushioning and “give” to the hooves and joints of your horse. Whether your discipline is Dressage, Barrel Riding, Reigning, or Western Style, we produce a material that allows you to put your best foot (or hoof) forward.

Thermal Sand

Whibco’s thermal sand is specialty blended product that meets the needs of electrical utilities looking for a non-corrosive, non-reactive material that demonstrates the thermal resistivity required for use in high voltage applications. Whibco is an approved producer of Thermal sand for both Peco Electric and Consolidated Edison Utilities have used our Thermal sand as a replacement for flowable fill. On projects where access is needed on a continuing basis, the material can be dug out by hand to continue on with the next day’s work.
