Every solid structure starts underground. A poorly poured foundation cracks, settles, and eventually pulls the rest of the building down with it — which is why foundation work is the part of construction you can't afford to cut corners on. Grande Concrete pours residential foundations across Greeley, CO: home additions, garages, ADUs, sheds, and outbuildings. With years working local soil and climate conditions, we know what foundation type fits your project and your site. Every pour is permitted, inspected, and built to local code.
Greeley, CO has specific requirements — frost depth, rebar spacing, vapor barriers, drainage. We pull permits, schedule inspections, and meet code without you needing to follow up.
Slab-on-grade, monolithic, stem-wall, and pier foundations each fit different uses and soil conditions. We help you pick the right type before we pour, not after problems show up.
A foundation for a single-story addition is different from one for a two-story garage with a workshop. We size and reinforce based on what's actually going on top.
Proper rebar placement, correct PSI mix, full curing time, sealed vapor barriers — these are the small details that decide whether a foundation lasts 50 years or 15.
We assess your soil, drainage, and grade. For larger foundations, we coordinate with your engineer or arrange engineering for the project.
We pull required permits and schedule inspections needed before, during, and after the pour.
We dig footings to required depth (below local frost line), install rebar cages, and set anchor bolts where needed.
Forms set to engineered specs, rebar tied per code, concrete poured at the right slump and PSI for the application.
Forms come off after the concrete reaches initial strength. We waterproof the exterior where required and let the foundation cure fully (typically 28 days for full strength) before framing begins.

Foundation type is the biggest driver — slab-on-grade is the most affordable; full-depth stem-wall or basement foundations cost more. Square footage and depth matter, as does soil condition (rocky soil costs more to excavate; soft soil may need engineered fill). Permit fees and engineering add to the project. Access matters for the concrete truck — tight sites need pumping, which adds cost.
For larger additions, garages, ADUs, and most permitted structures — yes. Smaller sheds and outbuildings often don't require engineering. We'll tell you what your project needs and help coordinate the engineer if required.
The pour itself takes a single day. The full timeline including excavation, forming, rebar, pour, cure, and inspection runs 2-3 weeks for a standard residential foundation.
Concrete reaches enough strength for framing in about 7 days. Full design strength (28 days) is the gold standard before heavy loads. We coordinate timing with your builder so framing starts as soon as the foundation is ready.
