Concrete Contractors in San Bernardino, CA

San Bernardino is the largest city near us and a big market for concrete contractors, with older housing, valley heat and some of the region's strongest autumn winds. The 2020 census counted 222,101 residents and 66,147 housing units, 96.1% of them occupied. The city's listed elevation is 1,053 feet, while Arrowhead Springs, its northernmost neighborhood, sits near 3,000 feet.

Concrete from several building waves

The city's census history shows two big growth spurts, about 45.8% between 1950 and 1960 and about 38.2% between 1980 and 1990, with just 5.8% from 2010 to 2020. Neighborhoods built in those waves now have concrete that is decades old. Common findings on older lots:

• Walks and driveway panels lifted by mature tree roots.
• Cracks that have opened wider after years of settling.
• Thin slabs poured without reinforcement.
• Surfaces worn rough by sun and traffic.

Pour days and the Santa Anas

The Cajon Pass forms part of the city's northwest border, and in autumn warm, dry air is channeled through it as the Santa Ana winds. In extreme cases they approach 60 mph. A strong, dry wind can stiffen the surface of fresh concrete in minutes and open cracks before the slab has set. During Santa Ana season we check the forecast the day before, move pours when gusts are expected, use wind breaks and start curing as soon as finishing is done.

More rain and more heat than the desert

San Bernardino averages about 16 inches of rain, hail or light snow a year, mostly in winter, and the July mean high is 96.2°F. The city recorded 118°F on July 6, 2018. That is more rain than the High Desert gets and more heat than the coast. Summer pours start early on a dampened base and are cured with water or compound. In winter, slope matters most, so rain leaves the slab instead of soaking its edges or running toward the house.

Fault country

The San Andreas Fault runs along the base of the mountains and through the city's northern areas. No slab is earthquake-proof, but reinforcement placed at mid-depth on supports keeps cracked pieces level and together instead of shifting into trip edges.

Pool decks for valley summers

With July highs above 96°F, backyard pools get heavy use, and so do the decks around them. Dark, smooth concrete gets hot and slick. We suggest a lighter color and a textured finish that grips when wet, an expansion joint at the coping so the deck and pool shell do not push on each other, and a slope that sends splash water to a drain or the yard rather than into the pool or toward the house.

Tree roots and older walks

Mature street and yard trees are common in the city's older neighborhoods, and their roots lift walks and driveway panels as they grow. When we replace a lifted section, we cut out the broken concrete, trim roots only where that is safe for the tree, rebuild and compact the base, and set the new joints so a future lift stays confined to one panel instead of cracking the whole run.

The street side of a project

If your project touches the curb, sidewalk or driveway approach, it is in the public right-of-way and the city may require a permit. We check with the City of San Bernardino before scheduling. Work fully on your property can follow different rules, and we sort that out at the estimate.
