Foundation Concrete Built to Support What Comes Next
Foundation and sitework concrete is typically the first concrete on a new project, and it sets the standard for everything built on top of it. Grade preparation, base compaction, reinforcement design, and footing depth all need to be right before anything else gets built. We spec foundation work to the site conditions and scope — not to a generic standard.

What Foundation and Sitework Projects Include
Foundation and sitework covers the full range of concrete that creates the structural base for buildings and site improvements: slabs-on-grade, stem walls, footings, grade preparation, and large flatwork.

Residential addition or detached structure
Garages, outbuildings, sunrooms, and home additions all start with a foundation pour. The scope is defined by the structure's size, load, and site conditions.
Commercial tenant improvement
Slab modifications, new flatwork sections, and structural pours for commercial spaces undergoing renovation or build-out.
New commercial construction
Foundation and sitework for new commercial buildings, coordinated with the general contractor's schedule.
Site grading and sub-base preparation
Grading, compaction, and sub-base work that needs to happen before a foundation or large slab can be poured.
What Matters on Every Foundations & Sitework Project
Footing depth below frost line
Kansas City's frost line is approximately 30 inches. Foundation footings need to extend below that depth to avoid heaving movement through freeze-thaw cycling.
Subgrade assessment and base prep
KC's clay subgrade can't support foundation loads without proper base preparation. We assess subgrade bearing capacity before specifying base thickness and compaction requirements.
Coordination with other trades
Foundation work often has to coordinate with framing, plumbing rough-in, and other trades. We factor coordination requirements into the written scope and timeline.
Reinforcement design
Foundation slabs and footings need reinforcement appropriate to the load they're supporting. This is specified in the written scope based on the structure and site.
Local Conditions That Affect This Work
Kansas City's clay soil, freeze-thaw cycles, and drainage patterns affect how this type of work should be specified and installed.
KC clay and foundation bearing capacity
Clay subgrade can compress or heave under foundation loads. Proper compaction and sometimes engineered fill are required before foundation pours on high-clay sites in Johnson County.
Frost depth for footings
Footings need to go to 30+ inches in the Kansas City area to stay below the frost line. This is required for structural concrete that needs to hold position through KC winters.
How We Approach Every Project
Site visit first. Written scope second. Nothing starts without your approval.
Start the ProcessRequest Estimate
Call, fill out the form on this page, or email us. Tell us about your project — residential or commercial, rough scope, timeline. We'll schedule a site visit.
Site Review
We visit the site in person. We check existing conditions, base conditions, drainage, grades, and anything relevant to the scope. This is where most problems get caught before they become surprises.
Written Scope
You receive a written quote covering the exact work: materials, specifications, prep requirements, finish type, timeline, and price. Nothing starts without your sign-off.
Prep, Pour & Finish
We execute to the agreed spec. Proper base prep, forming, reinforcement, pour, and finish. No shortcuts on what's underneath — that's where concrete work lasts or fails.
Final Walkthrough
We walk the completed work with you before we leave. Any questions get answered on the spot. You'll know what to expect during the cure period.
Foundations & Sitework Questions
Common questions about this service, timeline, specifications, and how we work.
View All FAQsWhat types of foundation concrete work do you handle?
We pour slabs-on-grade, footings, stem walls, and grade-beam foundations for residential additions and commercial projects. Scope is determined during the site review and specified in the written scope.
Do you handle the grading and base prep before the foundation pour?
Yes. Site preparation, grading, and base compaction are part of the foundation project scope. We don't pour on unprepared grade.
How do you coordinate with other trades on a foundation project?
We work with the project's general contractor or owner to sequence our work around framing, plumbing rough-in, and other trades. Coordination requirements are built into the written scope and timeline.
What PSI concrete do you use for foundations?
Residential foundation slabs typically use 3,000 to 4,000 PSI concrete. Commercial foundations may require higher PSI depending on the structure and load requirements. Mix design is specified in the written scope.
