Straight talk
Slab-on-Grade: what you should know first
A slab-on-grade is exactly what it sounds like: the concrete slab is the foundation. Sheds, shops, garages, additions, and plenty of buildings around here sit on one. Done right, it's an economical, permanent foundation. Done wrong, the whole building rides a slab that's moving.
There's no redo on a slab-on-grade — the building goes on top of it. Which is why we won't order concrete until the subgrade is compacted to where it needs to be, even if that means telling you the ground needs more work than you hoped.

How J Gehring builds it
Deep subgrade compaction
This is the job. We excavate to reliable ground, bring in the right base material, and compact it in lifts until it stops giving.
Thickened edges where loads land
The slab's perimeter and any bearing lines get thickened sections sized for the structure above.
Rebar throughout
A slab that carries a building carries steel. Grid on chairs, held where it works.
Frost considerations, handled honestly
Nebraska frost goes deep. Whether your project needs frost-protected edges or footings is a real conversation we'll have at the estimate, based on what you're building.
Good fit
What it's good for
- Shop and shed foundations
- Detached garage slabs
- Additions and small buildings
- Slab foundations on new residential construction
Honest pricing
What sets the price
- → Square footage and slab thickness
- → Thickened edges and bearing sections the plans call for
- → How much excavation and base material your ground needs
- → In-slab plumbing or conduit to coordinate
No number over the phone — Jerry walks your ground first, then the quote comes written and itemized.
Step by step
How the job runs
- 1
On-site estimate
Jerry walks your ground himself and gives you an honest read of what it needs — including whether your project should wait a season.
- 2
Written itemized quote + locked start date
You see exactly what you're paying for, and you get a start date in writing before work begins.
- 3
Pre-construction meeting
Before a tool comes out, we walk the plan together — layout, grades, access, and what to expect each day.
- 4
Base day: excavate + deep compaction
We spend the first day on the base. Deep subgrade compaction happens before any concrete is ordered.
- 5
Form, rebar, pour at 5"+
Forms set to grade, rebar in every pour — not an upcharge — and a minimum of five inches of concrete.
- 6
Joints cut on schedule + finish
Control joints get cut before the slab picks its own crack line, not days late. Then the finish you chose.
- 7
Final walk-around with you
Before the crew leaves, you and Jerry walk the whole job together. Questions answered on the spot.
