Concrete Contractors in Corona, CA

We are concrete contractors serving Corona, CA and the nearby cities of western Riverside County. We pour new driveways, patios and slabs, install stamped concrete and pool decks, and repair cracked, sunken or worn concrete. Corona sits at the upper end of the Santa Ana River Canyon, about 48 miles southeast of downtown Los Angeles, with the Santa Ana Mountains to the west and south. The climate is Mediterranean: hot, dry summers and mild winters with most of the rain between winter and early spring. Those conditions shape how concrete should be poured, cured and maintained here.

Summer heat is the main hazard for fresh concrete

Wikipedia's climate table for Corona lists average daily highs of 92 degrees in July and 93 in August, and a record high of 118. The city also logs about 3,265 hours of sunshine a year. Hot air, hot forms and a dry wind pull water out of fresh concrete fast. If the surface dries before the slab underneath, you get plastic shrinkage cracks, a weak dusty top layer and finishes that wear early. On hot days we start early, dampen the base and forms, keep finishing tight, and keep the new slab moist or covered with curing compound so it gains strength evenly.

Fall brings a different problem. Santa Ana winds blow through the area two or three times a year between October and December, and dry, gusty wind is hard on a fresh pour even when the temperature is mild. We watch the forecast and move a pour if needed rather than fight the wind.

Winter rain and drainage

Corona averages about 14 inches of rain a year (13.95 inches in the Wikipedia climate table), most of it in a few winter and spring months. When it comes, it comes in storms. Water that runs toward the house, pools against a garage, or soaks under a slab edge washes out the base and leads to settling and cracks. Every driveway, patio and pool deck we pour is sloped away from the house and toward a safe outlet, and we look at downspouts and planter beds that dump water where it does not belong.

Freeze-thaw damage is rare here. The record low in the climate table is 19 degrees, and average winter lows sit around 40 to 42. That is a real difference from colder states: concrete here fails mostly from heat, poor base, tree roots, drainage and age, not from ice and road salt.

Corona's housing is mostly 1980s to 2000s

Corona grew quickly. The city had 37,791 residents in 1980 and 124,966 by 2000, and the 2020 census counted 157,136. American Community Survey figures summarized by Point2Homes put the median year built for local homes at 1991, with 23.9% built in the 1980s, 26.4% in the 1990s and 18% in the 2000s. About two-thirds of homes are single-family detached.

That means a large share of driveways, walkways and patios in Corona are 20 to 45 years old. Concrete that age often shows the same issues: cracks that have widened and shifted, panels that have sunk near the garage or the street, root heaves from parkway and yard trees, worn or spalled surfaces, and sealers that wore off years ago. Some of that can be repaired. Some of it is past the point where repair makes sense. We tell you which is which.

What we build and fix

• Concrete driveways: tear-out and replacement or new pours, with a compacted base, proper thickness and planned control joints.
• Concrete patios: backyard slabs for seating, covers, outdoor kitchens and side yards.
• Stamped concrete: stone, slate, brick and wood-plank patterns with color, for patios, walkways and driveway borders.
• Pool decks: new decks, replacements and resurfacing with slip-resistant, cooler-to-the-touch finishes.
• Concrete slabs: pads for sheds, workshops, equipment, RV and trailer parking, and garage floors.
• Concrete repair: crack filling, leveling of sunken slabs, resurfacing and section replacement.

From first visit to finished slab

Measure and inspect. We size up the area, check the slope and drainage, look at the existing concrete and what it sits on, and ask how you will use the space.

Quote in writing. Removal, base, thickness, steel, finish, joints and sealer are each listed with a total.

Check the rules. If the job touches the curb, a public sidewalk or a driveway approach, or the slab will carry a structure, we confirm requirements with the City of Corona or the county for your address first.

Pour, joint and cure. The pour is timed to the weather, joints are cut or tooled, and the slab is kept moist while it cures. You get dates for walking, driving and sealing.

Getting the most from your concrete

Concrete in Corona lasts a long time when it is kept dry underneath and protected on top. HomeGuide puts the life of a well-maintained concrete driveway at about 30 to 40 years and a patio at 30 to 50 years. A few habits help: reseal decorative and stamped surfaces every few years, keep sprinklers from soaking slab edges, fill small cracks before water gets under them, and keep tree roots away from new work.
