Concrete Foundations Fort Collins
We pour strong, precise concrete foundations for home additions, garages, and large outbuildings.




Structural Concrete Pads
If you are planning a new home addition, detached garage, or large shed, the success of your build rests entirely on the concrete base. We pour strong foundations in Fort Collins that stand up to heavy loads and harsh weather. Above and Below Concrete brings over two decades of hands-on experience to structural projects across Colorado's Front Range. Our family-owned operation maintains an A+ rating with the Better Business Bureau because we do the job right from the dirt up.
Pouring a foundation requires serious exactness. We handle the complex math and tight formwork required to build a solid base. Our crew sets heavy steel reinforcement before the concrete trucks ever arrive. Fort Collins experiences intense summer heat and deep winter freezes. That heavy freeze-thaw cycle damages poor concrete work quickly. To prevent cracking and settling, we focus heavily on the hidden preparation below the surface. We thoroughly clear the site, compact the soil, and establish precise grading. We follow strict guidelines from the American Concrete Institute to control the mix and cure times properly.
Expansive soils are a known issue in many local neighborhoods. When the ground holds excess water, it swells and pushes against your structural concrete. When it dries out, the soil shrinks away and leaves the slab unsupported. We counter these tough soil conditions by bringing in proper base material. We compact that gravel base tightly so your new foundation has a stable, permanent resting place. We never skip on sub-grade preparation.
While our primary focus is residential projects like home additions and large shops, we also manage thick commercial pads. We build strong retaining walls to hold back heavy soil and manage water runoff around your property. Proper drainage grading is standard practice on all our structural jobs. If you need broader structural concrete work, we can assess your specific plans and explain how we will approach the pour.
Every job starts with a free, detailed estimate. We evaluate your property and review your plans to give you transparent pricing. You get clear numbers with zero hidden fees. You deal directly with our local ownership team throughout the entire build. We show up on time, communicate clearly, and leave your job site completely clean when the work is done.

Materials & Specs
Foundation Materials We Use
High-Strength Concrete
We use specific, heavily engineered concrete mixes designed for structural applications. The mix holds up to heavy point loads from framing and roofing.
Steel Rebar Grids
Concrete is incredibly strong under compression but needs help with tension. We place thick steel rebar to hold the slab together tightly over decades of use.
Compacted Gravel Base
We use proper structural fill and gravel below the slab. This gives the concrete a stable place to rest while allowing ground moisture to drain away safely.

What Affects Foundation Costs
The Contractor You Choose
Cheaper quotes from unlicensed crews carry massive risks. Above and Below Concrete is an experienced, BBB A+ accredited contractor with a five-star reputation. Hiring professionals means your job is protected and built to local codes.
Overall Footprint Size
Larger home additions and oversized detached garages require more concrete, more steel, and extra labor hours. The total square footage directly drives the material cost.
Site Excavation Needs
Hard-to-reach backyards or rocky Fort Collins soil conditions can require specialized heavy equipment for proper clearing. Steep grades also demand extra dirt movement before we can pour.
