Capitol Aggregates, Ltd.

United States

Base materials consist of a combination of crushed stone, rock fines and clay. This material is used in foundations and road building to help prepare the area for concrete and asphalt paving. Capitol sells base materials at its Delta Materials and Solms Road quarries.

Crushed stone is created through the mining and crushing of rock. The rock is crushed into several different graded sizes for use in applications including ready mix concrete, asphalt and decorative stone. Gravel is created by river erosion, resulting in smooth and rounded products. Finished products can be either smooth and rounded or crushed, to meet the specific job requirements. Capitol sells gravel at the Austin River Sand and Gravel, Medina River Sand and Gravel, and Hoban Sand and Gravel plants. Capitol produces crushed stone at its Delta Materials Quarry.

Natural sand is created by river erosion, resulting in smooth and rounded products. Manufactured sand is created during the stone crushing process, resulting in a more angular and coarse product. Capitol sells natural sand at the Austin River, Medina River, and Hoban Sand and Gravel plants. Capitol offers manufactured sand at our Delta Materials quarry.
