Flatwork surrounding a home- the driveway, patio, and sidewalks- can make a powerful first impression on a potential owner. Well done concrete work contributes favorably toward this anticipation of what may be found inside; badly done work detracts. Following are steps to be taken in building a good driveway: prepare the subgrade thoroughly; provide good drainage; provide properly spaced joints; use a concrete mix with adequate air content; finish with a texture that provides skid resistance; and cure for at least 5 days. Driveway slabs can develop serious cracking and faulting from settlement if the soil is not compacted sufficiently to furnish continuous support, particularly over trenches and other backfilled areas. Compaction of the subgrade will be needed if test driving of a light truck over the prepared site depresses the soil more than a slight amount. In areas where the soil does not lend itself to proper compaction grass, sod, and roots as well as soft or mucky spots must be dug out to a firm base and the area filled with the same kind of soil as the rest of the subgrade. Small slipform pavers are now being used for efficient construction of both driveways and sidewalks in residential developments. Otherwise placing and finishing procedures are essentially the same as those for concrete floors. After the driveway has been troweled or floated to a dense, uniform and plane surface it is common to draw a stiff-bristled broom transversely across it to make it nonskid. Decorative nonskid surfaces can also be made by producing exposed aggregates surfaces. Driveways are cured in the same manner as concrete floors and for the same length of time. Curing compounds for hot weather preferably contain white pigment to reflect the rays of the sun and prevent excessive heat buildup.
