About Us

Ross Island leads in environmentally responsible methods for production and transportation of all aggregates for our manufactured construction products.Use of barges for aggregates transport reduces CO2 Greenhouse Gas Emissions by 73% when compared to the 70 standard truckloads one barge replaces.

All aggregate based manufactured products including ready mixed concrete, asphalt and bagged products are not moved by truck until they are loaded as finished products for delivery. All Ross Island delivery vehicles use biodiesel fuel.

Ross Island bagged and mixed concrete products meet LEED (Leadership in Energy and Environmental Design) guidelines for construction waste management (MR2) recycled content (MR4) and regional-local sourcing (MR5)

Ross Island has an ongoing reclamation program to manage the lagoon created during 75 years of in water mining that ended in 2001. This is in cooperation with State and Federal Agencies.

Ross Island efforts insure that additional upland forest, riparian/emergent wetland habitat and shallow water habitat are being created.
