A. A general value for concrete's coefficient of thermal expansion is about 5.5 millionths/° F. If an unrestrained, 100-foot-long slab on grade was exposed to a 100° F temperature drop throughout its cross-section, it would contract about .66 inch (100 feet x 12 inches/foot x 100° F x .0000055). Since the slab is restrained by friction ...

Spread and compact the DG in even layers. Once you have the decomposed granite, you'll spread it over the patio area in lifts. Lifts are simply incremental layers that allow you to compact only a small thickness at a time. We recommend laying down and compacting your DG in lifts of 1.5-2" at a time until you have your full thickness.
