Our Materials
Asphalt
A mixture of sand, stone or gravel components. Usually compacted to 1 ½” and covers a crushed aggregate base or foundation.
Oil and Stone
Consists of either bluestone or burgundy gravel. Base combines layers of recycled aggregate, street tar and blacktop.
Stamped Concrete
Concrete
Stone-like material used for various structural purposes. Usually consists of a mixture of cement and various aggregates such as sand, pebbles, gravel or shale with water. Once this mixture hardens, it becomes concrete. Concrete is virtually maintenance free, lasting up to five times longer than asphalt.
