Concrete Slabs and Pads for Different Uses
Every concrete slab must be matched to its specific structural load, subgrade soil conditions, and building requirements. We construct reinforced concrete pads for residential and light commercial applications.
Garage Concrete Slabs
Poured at 4 to 6 inches thick over compacted road base, featuring heavy steel rebar grids tied into continuous turned-down edges to support vehicle tires and floor jack loads.
Storage Shed Pads
Level concrete pads that eliminate rotted wooden shed floor joists, keeping lawn mowers, snowblowers, and garden tools elevated off damp yard soil.
Shop & Metal Building Slabs
Engineered flatwork slabs for detached workshops, metal pole barns, and hobby shops poured to withstand heavy machinery and tool chests.
Equipment & Generator Pads
Thick reinforced concrete pads built for HVAC condenser units, emergency backup generators, commercial trash compactors, and hot tubs.
Addition Slabs & Footings
Poured concrete foundations and monolithic slab-on-grade floors for home room additions, sunrooms, and enclosed porch conversions.
Replacement Slabs & Demolition
Breaking up cracked, unreinforced, or sunken concrete slabs, excavating unstable subgrade clay, and repouring a properly reinforced concrete floor.
What Is the Difference Between a Slab and a Foundation?
In plain language, a concrete slab is the flat horizontal surface that forms your finished floor or supporting pad. A foundation includes the deeper structural elements — such as footings, turned-down thickened edges, or stem walls — that transfer building loads down into stable subgrade soil.
A uniform 4-inch or 6-inch concrete pad poured over compacted aggregate base. Ideal for unheated sheds, hot tubs, generator equipment pads, and patio extensions.
The slab surface and perimeter footings are poured at the same time in one continuous batch. The outer edge drops down 12 to 18 inches to support garage or workshop walls.
Deep frost-line footings or stem wall systems constructed from approved architectural or engineering drawings for living space home additions.
Aurora Soil & Frost Line Factors
In Aurora, Colorado, the official frost depth is 36 inches below finished grade. Enclosed living additions or specific commercial structures require footings below frost depth to prevent seasonal frost heave.
Unheated accessory structures like detached garages or storage sheds frequently utilize monolithic turned-down edge slabs when permitted by local city codes.
What We Need Before the Pour
Smooth concrete execution relies on thorough prep work. Depending on your project scope, having clear dimensions and site information ready helps us provide an accurate estimate and construct a compliant slab.
Dimensions & Drawings
Exact length, width, and shape specifications. For detached metal buildings or home additions, having stamped architectural or engineering plans ensures footings match load points.
Intended Structural Load
Knowing whether the slab will hold a light lawn shed, a 2-car SUV garage, a 20,000 lb RV, or heavy industrial machinery dictates concrete mix PSI strength and rebar grid sizing.
Utility Locates & Setbacks
Public utility lines (gas, electric, water) must be marked prior to excavation. Property line setback limits set by the City of Aurora determine allowable slab perimeter placement.
Permits & Site Access
Building permits, property owner approvals, and gate access widths (minimum 36 inches for bobcats or wheelbarrows) must be verified before site excavation begins.
The Work Below the Concrete Matters
A concrete slab is only as stable as the subgrade beneath it. Pouring concrete directly over uncompacted topsoil or organic grass leads to settlement voids and severe structural cracking.
We strip off grass, roots, and soft topsoil until reaching hard native clay or sandy subgrade soil to establish a stable base elevation.
Imported crushed aggregate road base is spread 4 to 6 inches thick and mechanically plate-compacted to provide a rigid, non-yielding base layer.
Instead of thin wire mesh that settles to the dirt, we elevate #4 (1/2-inch) steel rebar grids on plastic chairs so steel stays embedded in the middle of the slab.
When requested for enclosed garage or workshop slabs, heavy poly vapor retarder sheeting is laid under concrete to block ground moisture migration into finished spaces.
2x6 or 2x8 dimensional lumber forms are staked and braced rigidly to hold heavy wet concrete pressure without bowing or blowing out perimeter lines.
Forms are laser-leveled to ensure garage floor slabs pitch subtly toward overhead doors while maintaining exact door threshold height requirements.
What to Expect During the Project
Scope & Site Review
We confirm intended slab load, review customer dimensions or plans, inspect equipment access routes, and coordinate utility line markings.
Excavation & Base Prep
Bobcats or excavators dig out sod and soft clay. Aggregate road base is placed and plate-compacted to strict compaction density.
Forming & Rebar Grid
Form lumber is staked to laser elevation. Steel rebar grid is tied, elevated on chairs, and turned-down edge footings are dug if required.
Pre-Pour Verification
We inspect form squareness, rebar spacing, grade depth, and anchor bolt placements before concrete truck arrival.
Concrete Placement & Trowel
Ready-mix concrete (4,000+ PSI air-entrained) is placed, screeded, bull-floated, and steel-troweled for a dense, smooth floor finish.
Saw Cuts & Site Cleanup
Control joints are saw-cut within 24 hours. Forms are stripped, surrounding soil is backfilled, and curing guidelines are handed over.
What Affects the Cost of a Slab or Foundation?
Structural slab pricing depends directly on structural specifications, site accessibility, and subgrade material needs:
- Overall square footage and slab depth (4 in vs 6 in vs 8+ in heavy industrial)
- Monolithic turned-down edge footings or separate deep frost footings
- Excavation depth and cubic yards of imported class 6 aggregate base
- Steel rebar gauge size (#3 vs #4 vs #5) and grid spacing (12 in vs 18 in centers)
- Concrete pump truck requirements for narrow or rear-yard site access
- Demolition and haul-away fees for old concrete or asphalt removal
