GFL mines, also known as borrow pits, supply clean sand, clay, general fill, and topsoil for construction jobs throughout Tampa Bay and Central Florida.Our primary mine, FDOT Mine (#14-38) for embankment and mechanically stabilized earth (MSE) backfill, is located in Dade City and has over 12 million cubic yards of reserve material. We provide a range of soil products at our various locations on a limited basis.

Our clay liner materials have historically been used on landfill and environmental projects throughout the state of Florida. Our natural soil products are mined from sources without the need for dewatering and can serve all project types and sizes without downtime or delay. This allows us to contribute to Florida’s statewide recycling goal of 75% and to preserve natural resources.
