Top-Rated Concrete Contractor in Pomona CA - Foundations That Outlast Aging Soils

A significant portion of Pomona's residential housing was built between 1940 and 1970, which means much of the city's concrete - foundations, driveways, sidewalks, and patios - is now between 55 and 85 years old. Concrete from that era was installed with the materials and methods of the time, which typically meant thinner slabs, little or no steel reinforcement, and minimal attention to soil preparation. The clay-heavy soils common across the eastern San Gabriel Valley have been expanding and contracting under those slabs through every rainy season and every summer dry spell for decades. The result is concrete that looks stable from the outside until it is not, and when it goes, it tends to go in ways that require full replacement rather than surface patching.

Pomona also sits in the path of Santa Ana winds, which blow hot and dry out of the inland desert every fall and into winter. These winds - which can exceed 50 mph during strong events - dry out the soil rapidly after early rain events, amplifying the shrink-swell cycle that stresses foundations and flatwork. Summer temperatures that regularly top 95 to 100 degrees Fahrenheit add to the load on concrete surfaces through heat expansion and UV degradation of the top layer. A contractor unfamiliar with this specific combination of clay soils, Santa Ana events, and summer heat will not prepare the base or specify the mix design that Pomona conditions actually require.

Pomona is one of the larger cities in Los Angeles County, with over 150,000 residents spread across roughly 23 square miles at the eastern end of the San Gabriel Valley. The city's housing stock tells the story of Southern California's mid-century growth - a large share of Pomona's single-family homes were built between 1940 and 1970, giving the city some of the oldest residential concrete in the region. The Lincoln Park neighborhood near downtown contains Victorian and Craftsman homes dating to the late 1800s and early 1900s, making it one of the most intact historic residential areas in the Inland Valley. Beyond Lincoln Park, most of Pomona consists of ranch-style and bungalow homes on modest lots - typically 5,000 to 7,000 square feet - with stucco exteriors and small backyards where drainage and grading often need attention.

Pomona is home to California State Polytechnic University, Pomona - one of the largest campuses in the Cal State system - and the Fairplex, which hosts the Los Angeles County Fair each September and is one of the most recognized local landmarks in the region. The city borders Ontario and Chino to the southeast and south, and many Pomona homeowners have property or family nearby in those communities. We also serve Chino, where clay soil conditions and mid-century housing create a very similar set of concrete maintenance needs.
