Concrete Slab & Foundation Work

The Importance of a Solid Foundation

Your foundation is literally what everything else rests on. Whether you are building a new home, adding a garage, or constructing a shed or outbuilding, the foundation determines how well your structure performs over time. A properly installed concrete foundation prevents settling, cracking, and moisture problems that can plague buildings for years.

Here in Wilkes-Barre, PA, foundations face unique challenges. Our freeze-thaw cycles put stress on concrete. Soil conditions vary across the area, affecting how foundations settle. Water management is critical to prevent basement flooding and foundation damage. At WBC Wilkes-Barre Concrete, we understand these local factors and design foundations that perform in Pennsylvania conditions.

Whether you need a simple slab for a garage or a full basement foundation for a new home, the principles remain the same. Proper excavation, correct depth, quality materials, and skilled installation all matter. Cutting corners on foundation work is never worth it. The cost of repairing foundation problems far exceeds the cost of doing it right the first time.

Types of Concrete Foundations We Install

Different projects require different foundation approaches. We work with several foundation types depending on your needs, building design, and site conditions.

Slab-on-grade foundations are popular for garages, shops, and additions because they are cost-effective and work well on stable soil. The concrete slab serves as both foundation and floor. These typically range from 4 to 6 inches thick and include reinforcement to prevent cracking.

Full basement foundations involve more complexity. We excavate to the proper depth, install footer forms, pour footers, then build and pour foundation walls. The basement slab comes after the walls cure. This approach creates valuable living or storage space but requires careful waterproofing and drainage planning.

Our Foundation Installation Process

Quality foundation work follows a systematic process. Every step matters for the final result. We start by reviewing building plans and site conditions. Soil type, drainage, and local building codes all influence how we approach your foundation.

Site preparation begins with layout and excavation. We mark the foundation location precisely and excavate to the required depth. The bottom of the excavation must be level and stable. If we encounter poor soil, we may need to dig deeper and bring in better material. Proper drainage is established at this stage, often including gravel base and drainage pipe.

Forms are built to contain the concrete and create the foundation shape. For slabs, this means perimeter forms. For walls, we use specialized forming systems that hold concrete in place while it cures. Footers are poured first if your design requires them. These wider sections at the base distribute building weight into the soil.

Reinforcement is critical. We install steel rebar according to engineering specifications. The rebar grid gives concrete internal strength and prevents cracking. For residential work, we typically use number 4 or number 5 rebar spaced 12 to 18 inches apart. Anchor bolts are positioned to secure the structure to the foundation.

The concrete pour requires careful attention. We use concrete mixes designed for foundation work with proper strength ratings. As concrete is placed, we work it to eliminate air pockets and ensure complete filling of the forms. The surface is leveled and finished appropriately. Curing is carefully controlled to achieve maximum strength. Foundation work cannot be rushed.

Critical Elements for Long-Lasting Foundations

Several factors separate foundations that last a lifetime from those that develop problems. Drainage tops the list. Water is the enemy of foundations. We ensure water flows away from your foundation through proper grading, installing drainage systems where needed, and waterproofing below-grade surfaces.

Thickness and reinforcement must meet or exceed code requirements. Residential slabs are typically 4 inches minimum, but we often recommend 5 or 6 inches for durability. Foundation walls need adequate thickness based on height and soil pressure. Skimping on concrete thickness or reinforcement creates future problems.

Proper curing is essential. Concrete gains strength as it cures over several weeks. We protect fresh concrete from temperature extremes and ensure adequate moisture during curing. This is especially important in Pennsylvania where weather can be unpredictable. Foundation concrete that cures properly develops the strength needed to support your structure for decades.

We also consider expansion joints, control joints, and crack control measures. Concrete naturally expands and contracts with temperature changes. Properly placed joints allow this movement without causing random cracking. For larger slabs, we include expansion joints to separate sections. This attention to detail prevents many common foundation problems.

Working With Your Builder or Contractor

Foundation work typically happens early in construction projects. If you are working with a builder or general contractor, we coordinate closely to ensure everything goes smoothly. We review plans, confirm specifications, and schedule our work to keep your project on track.

Communication is key. We make sure everyone understands the foundation design, timeline, and any site considerations that might affect the work. If changes are needed based on what we find during excavation, we discuss options and solutions before proceeding. No one likes surprises during construction.

For homeowners managing their own projects, we can work directly with you. We help you understand what is needed, guide you through the process, and coordinate with your other contractors. Whether you need a concrete driveway foundation or a full building foundation, we bring expertise that ensures your project succeeds. Many clients also need retaining walls to manage grade changes around new foundations.
