Concrete Slabs & Foundations in Ontario, CA
Patio slabs, garage and shed slabs, equipment pads, and slabs and footings for room additions and ADUs — built on a properly compacted base.
Concrete slabs and foundations are the base for many projects around your home. At Soto Concrete, we pour concrete slabs and foundations Ontario CA homeowners need — from a simple patio slab to garage and shed slabs, pads for AC units and spas, and slabs and footings for room additions and ADUs. With 26+ years of experience, we know that a lasting slab starts below the surface.
Every slab begins with site preparation and a compacted base, then forming and reinforcement where needed, followed by pouring and finishing. We work from your project plans and follow local permit requirements where they apply. Whether you need a concrete foundation contractor for an addition or a patio slab for your backyard, we explain your options and give you a free estimate first.
