Concrete Slab & Foundation Work

Your Foundation Is Everything

Every structure starts with its foundation. Whether you are building a new home addition, a detached garage, a workshop, or a commercial building, the foundation is the single most important part of the project. Get it wrong and everything built on top of it suffers. Cracks in walls, doors that will not close properly, uneven floors, and structural problems all trace back to foundation issues. That is why foundation work demands precision, experience, and an understanding of the local soil and climate conditions that affect how concrete performs over time.

Here in the Sun City area, we deal with desert soils that present specific challenges. Expansive clay soils can swell when wet and shrink when dry, putting pressure on foundations if they are not designed correctly. Caliche, a hard calcium carbonate layer common in Arizona, requires special excavation techniques. At Sun City Concrete Works, we have the experience and knowledge to handle these local conditions. We design and pour foundations that account for our unique soil and climate, giving your structure a solid base that will perform reliably for decades.

Types of Foundation Work We Handle

• Residential slab-on-grade foundations for home additions and new construction
• Garage and carport foundations built to support vehicle weight and equipment
• Shed, workshop, and accessory building foundations
• Commercial building foundations for offices, retail, and industrial spaces
• Equipment pad foundations for HVAC units, generators, and other machinery
• Floor slabs for interior remodeling and room conversions

No matter the size or type of foundation, the same principles apply. Proper site preparation, correct thickness, adequate reinforcement, and careful curing are non-negotiable. We bring the same level of attention and quality to a small shed pad as we do to a large commercial foundation because every project deserves to be built right.

How We Build Foundations That Last

Foundation work follows a detailed process that we have refined over years of experience. The first step is always a thorough site evaluation. We assess the soil conditions, check for drainage issues, verify utility locations, and review any engineering plans or building requirements. This information guides every decision we make during construction. Skipping or rushing this step is one of the most common reasons foundations fail, and we never cut that corner.

Excavation comes next. We dig to the specified depth and dimensions, ensuring the excavation is level and clean. For slab-on-grade foundations, we typically excavate several inches below the finished grade to accommodate the gravel base and the concrete slab itself. Once the excavation is complete, we install a compacted gravel base that provides drainage and a stable platform for the concrete. In Arizona, managing moisture under the slab is critical, so we often install a vapor barrier to prevent ground moisture from migrating up through the concrete, which can damage flooring and create moisture problems inside the building.

Before pouring, we build forms to define the foundation's shape and edges, then install reinforcement. Depending on the project's requirements, this might be rebar in a grid pattern, post-tension cables, or welded wire mesh. The reinforcement gives the concrete tensile strength and helps it resist cracking from soil movement and loading. When everything is checked and approved, we pour the concrete, screed it level, and finish the surface. For foundations that will be exposed, we trowel the surface smooth. For those that will be covered by flooring, we leave a slightly rougher texture for better adhesion. Control joints are placed at strategic intervals to manage where any shrinkage cracking occurs. If the project requires it, we coordinate with inspectors to ensure everything meets code before and after the pour. For elevated structures that need entry points, our concrete steps and stairs services complement foundation work perfectly.

Commercial Slabs and Specialty Applications

Commercial and industrial slab work has its own set of requirements. These slabs often need to support heavier loads, resist wear from equipment and traffic, and meet stricter specifications than residential work. We work from engineered plans and follow specifications exactly, ensuring the concrete meets the required strength, thickness, and reinforcement standards. Whether it is a warehouse floor, a retail space, or an equipment pad, we deliver slabs that perform under demanding conditions.

Flatwork is a critical skill in commercial concrete. The surface needs to be level and flat within tight tolerances, especially for buildings that will use forklifts, pallet jacks, or other wheeled equipment. Uneven floors cause operational problems, damage equipment, and create safety hazards. We use laser-guided screeding and precision finishing techniques to achieve the flatness standards that commercial projects demand. For floors that will remain exposed, we can provide polished or burnished finishes that look professional and are easy to maintain.

Equipment pads are another specialty we handle regularly. HVAC systems, generators, compressors, and other heavy equipment need solid, level pads that can support their weight and vibration without cracking or settling. We size and reinforce these pads based on the equipment specifications, ensuring they provide stable, long-lasting support. Proper elevation and drainage are also factored in to keep water away from the equipment and prevent erosion around the pad.
