Concrete Contractors in Wrightwood, CA

Wrightwood sits at 6,208 feet in the San Gabriel Mountains, above the Swarthout Valley, and the work concrete contractors do here looks nothing like flatwork on the desert floor. The town's climate table shows about 61.8 inches of snow in an average year, with February the snowiest month at about 24.8 inches, and 21.06 inches of total precipitation. A lot of winter precipitation falls as snow. A plain slab that would last decades in Hesperia can start to scale and pop within a few winters at this elevation.

Why mountain concrete flakes

Concrete is porous. Meltwater soaks into the surface, freezes overnight and expands, then thaws the next afternoon. Each cycle pries at the paste near the top, and after enough of them the surface starts to flake in thin chips. Shovels, plows and chains speed up the wear, and deicing salts make scaling worse. Better mix design, finishing and curing are what prevent it, not a thicker slab.

What goes into a Wrightwood pour

Air entrainment. The mix carries billions of microscopic air bubbles that give freezing water somewhere to go. Every exterior slab we pour here gets it.

Water kept in check. Adding water at the truck makes concrete easier to place and weaker at the surface. We do not do it.

Finishing at the right time. Working bleed water back into the surface weakens the top layer, so finishing waits until the bleed water is gone.

A full cure and a sealer. The slab needs to gain strength before its first hard freeze, and a penetrating sealer slows water absorption after that.

Sand, not salt. For the first winter, we ask owners to use sand for traction.

Steep drives and snowmelt

Many Wrightwood lots slope, and a sloped driveway needs a deeper broom texture so tires and boots grip on packed snow. Snowmelt runs fast on a grade. We plan cross slopes, edges and drains so water leaves the concrete instead of running along its edge, where it can undercut the base or refreeze into an ice sheet across the drive.

Cabins, full-timers and second homes

Wrightwood began as a vacation community, and many 1930s resort cabins still stand downtown; today more than 4,000 people live here full time. The 2020 count found 2,664 housing units with a quarter of them (25.5%) vacant, which reflects the second homes in town, and owners lived in 78.9% of the occupied ones. Old cabins often sit on small, thin slabs with steps heaved by decades of frost. For owners who are only up on weekends, we can schedule the work for when the house is empty and send photos as it goes.

Fire and evacuations

In September 2024 the Bridge Fire brought evacuation orders to Wrightwood, along with Camp Williams, River Community and Mount Baldy. More than 56,000 acres burned in all, and three Wrightwood homes were destroyed. Part of the town had also been evacuated during the Blue Cut Fire in 2016. Owners who are rebuilding or hardening a property often use concrete for noncombustible ground close to the house: a walk in place of a bark bed, a slab under the woodpile and propane tank, a patio instead of a wood deck against the wall.

Pouring season and water

Fresh concrete must not freeze before it gains strength, so most Wrightwood pours are scheduled for the warmer months. In spring and fall we pour early, cover the slab with insulating blankets overnight and watch the forecast closely. Golden State Water supplies the town with groundwater pumped from several canyon underflows as well as the Swarthout Valley and Sheep Creek areas, and we keep our water use on site to what curing and cleanup need.
