We have fir bark, wood mulch, organic compost, hogfuel and screened and unscreened arborists chips. Whether you’re looking for just the right color or the perfect size, we’ve got you covered!

Rock and Sand – A beautiful landscape starts with a solid quality foundation. We offer a wide range of rock and sand for decorative purposes as well as drainage, driveways, pathways, road and paver base. We also carry White River basalt rockery and imported Canadian rockery for your gorgeous rockeries and retaining walls.

Recycled Materials – Recycled concrete and asphalt are perfect products for those areas that need an economical replacement for crushed rock. Concrete can be used for any job that crushed rock is normally used for including driveways and roads, a base for pavers and compactable fill. Other uses include a base for paved driveways, filling potholes and setting fence posts. Crushed asphalt can be spread during hot weather and rolled out to a smooth surface creating an almost paved look for driving and parking. It is an excellent material on driveways to reduce dust and fix potholes.
