Concrete Slab & Foundation Work
Professional concrete slab and foundation services that provide the solid base your building project needs.
The Foundation of Every Structure
Your building is only as good as its foundation. Whether you're planning a new home, adding a room, building a garage, or constructing a storage shed, the concrete slab foundation is what keeps everything level, stable, and protected from moisture. We specialize in foundation work throughout San Luis Obispo County, bringing the technical expertise and attention to detail that this critical work demands.
Foundation work isn't something you can cut corners on. Poor foundation work leads to cracks, settling, moisture problems, and structural issues that cost far more to fix later. That's why working with experienced professionals matters. We understand local soil conditions, proper drainage requirements, and building codes specific to San Luis Obispo County.
San Luis Concrete has poured foundations for residential and commercial projects of all sizes. From small storage buildings to large custom homes, we bring the same level of precision and quality to every job. Your project deserves a foundation that will last as long as the structure itself.
Types of Foundation Work We Handle
Different projects need different foundation approaches. We work with you and your builder or architect to determine the best foundation type for your specific situation. Factors like soil conditions, building size, local codes, and budget all play a role in choosing the right approach.
Foundation Services
- •Slab-on-Grade Foundations: The most common type for residential construction, poured directly on compacted soil with proper moisture barriers.
- •Monolithic Slabs: Foundation and floor poured together in one piece for faster construction and fewer joints.
- •Stem Wall Foundations: Raised foundation walls that create crawl space and work well on sloped lots.
- •Garage and Accessory Building Slabs: Properly sized and reinforced foundations for detached structures.
- •Commercial Foundation Slabs: Engineered foundations designed to handle heavier loads and equipment.
Each foundation type has specific requirements for reinforcement, thickness, and preparation. We follow engineering specifications exactly and work closely with inspectors to ensure everything meets code. Our goal is to deliver a foundation that passes inspection the first time and performs flawlessly for decades.
Our Foundation Installation Process
Foundation work requires careful planning and precise execution. We start by reviewing your plans and conducting a site evaluation. This helps us identify any challenges early and plan the best approach for your specific location and soil conditions.
Site preparation is the first critical step. We excavate to the proper depth, ensuring stable soil and proper drainage. The ground must be level and compacted to prevent settling. We install gravel base material when needed and place moisture barriers to protect against water intrusion from below.
Forming and reinforcement come next. We set up precise forms that define the foundation's edges and ensure proper dimensions. Steel rebar or wire mesh reinforcement is positioned according to engineering specifications. This reinforcement is what gives the concrete its strength and helps prevent cracking as it cures and ages.
The concrete pour is where everything comes together. We use high-quality concrete mixed to the right specifications for foundation work. Our team works efficiently to place and finish the concrete before it begins to set. Proper finishing and curing are essential for achieving the strength and durability your foundation needs.

Frequently Asked Questions
How long does a foundation take to cure?+
Concrete reaches most of its strength in the first seven days, but full cure takes about 28 days. You can typically start building on the foundation after seven to ten days, depending on weather and specific requirements. We monitor the curing process and advise you on the right timing for your project. Proper curing is essential for strength, so rushing this step can compromise your foundation. Our mild San Luis Obispo weather actually helps concrete cure consistently without extreme temperature swings.
What causes foundation cracks?+
Most foundation cracks come from poor soil preparation, inadequate reinforcement, or drainage problems. That's why proper site prep and following engineering specifications matter so much. We take extra care with soil compaction and moisture barriers to prevent settling. Control joints are placed strategically to direct any minor cracking to planned locations. When foundations are built right from the start with quality materials and proper techniques, serious cracking problems are rare. We also offer concrete repair services if you have existing foundation issues that need attention.
Do I need permits for foundation work?+
Yes, foundation work almost always requires building permits and inspections. This protects you by ensuring the work meets local building codes and safety standards. Your builder or contractor typically handles permit applications, but we work closely with inspectors throughout the process. We schedule required inspections at key stages like pre-pour and final inspection. Our work consistently passes inspection because we follow code requirements precisely. Having proper permits also protects your property value and avoids problems when you sell your home later.
