Sizes & Colors
Decomposed Granite
Decomposed granite is a mix of fine particles and small chunks, typically 1/4" and smaller. Colors include gold, tan, brown, gray, and reddish-brown depending on the granite source. Stabilized DG (with resin binder) creates an even firmer surface.
Topsoil
Fine, crumbly soil texture when screened. Dark brown to black color indicates high organic content. "Screened" topsoil has been run through a 3/8" or 1/2" screen to remove debris. Blended topsoil may include compost for extra nutrients.
