Decomposed Granite Patio Ideas. Created when granite rock naturally decomposes over millions of years, decomposed granite is a less expensive paving alternative to stone or concrete for an attractive, efficient patio. Decomposed granite (often referred to as DG) is a type of gravel that consists of small particles of granite rock.
It provides nutrients to the soil and lasts for a longer time than mulch. Decomposed Granite is great as a xeriscaping ground cover. Secure the pavers by striking them with a rubber mallet so they embed in the sand.
Spread an inch-thick layer of sand over the decomposed granite.
Thoroughly soak the material with water.
This video shows how Decomposed Granite is professionally installed. Begin by marking out the area where you want the decomposed granite patio to go. You donâ€™t need special clamps, just some packing tape.
