Concrete Contractor in Sandy, Utah

Slopes concentrate the problem. Snowmelt runs downhill, gathers at the low edge of a slab or against a wall, and freezes again overnight, dozens of times a season. Air-entrained concrete, footings below frost depth (about 30 inches in most of the valley, sometimes more on high benches), steady drainage and no de-icing salt on new work the first winter keep that cycle from prying things apart.

Walkouts nearly always do, since sawing a doorway into a foundation wall means installing a header, and building departments usually ask for an engineer's letter describing it. A retaining wall tends to cross into engineered territory past roughly 4 feet, or sooner when a driveway, a building or more hillside bears down on it from above. Driveway approaches need a city permit, many HOAs want to see plans first, and nobody digs until 811 has had the utilities marked.

Grade is the big one, because slopes add excavation, forming and often walls. After that come access for equipment and the concrete truck (a pump may be needed when the truck cannot reach), drainage work, engineering and permits, how much old concrete comes out, and the finish. A walkout or a tiered wall involves far more steps than a flat patio of similar size.

Thirty-five towns around Sandy, among them Draper, Cottonwood Heights, Midvale, Murray, Holladay, Millcreek, South Jordan, Riverton, Herriman and Bluffdale in Salt Lake County, plus Alpine, Highland, Lehi and American Fork to the south, Salt Lake City to the north and Tooele to the west. Each town has its own page under service areas.

Often, yes. Footings, foundation cuts and walkout work carry on through the cold months with protected subgrade, heated or blanketed pours, and a firm rule against pouring on frozen ground. Driveways, patios and stamped surfaces are mostly poured from spring through fall. On site, most projects run from several days to a couple of weeks, depending on excavation and engineering.

Yes, usually by cutting into the slope, building the low side up behind a retaining wall, or a mix of both. A patio on fill needs that fill compacted in thin layers so it does not settle later. The slab still falls gently away from the house, with a place for the water to go at its low edge.

Nearly always because of water underneath them. Runoff from above, a downspout emptying at the slab edge, or soil that settles once it is soaked can let a section drop or tip toward the house. Fixing the water first, then lifting, repairing or replacing the concrete, keeps the problem from coming back.
