Why Choose Our Garage Floor Slabs
Garage floors take heavy abuse — vehicle weight, road salt, oil drips, tool drops, and freeze-thaw exposure. We pour garage floors designed for this punishment: 4-6 inch thickness, 3,500-4,000 PSI air-entrained concrete, welded wire mesh or fiber reinforcement, and proper slope toward the overhead door for drainage.
Signs You Need Garage Floor Slabs
1. Severe cracking or settlement
Large cracks, heaved sections, or significant settlement make the floor uneven and unusable for vehicles or storage.
2. Surface spalling
The top surface is flaking, pitting, or crumbling from salt damage or poor original mix design.
Our Process
Step 1 — Remove old slab
Saw cut perimeter, break up and remove old concrete, haul debris.
Step 2 — Subbase preparation
Excavate to proper depth, compact subgrade, install granular subbase, and verify grade and slope.
Step 3 — Form, reinforce & pour
Set perimeter forms, install reinforcement, pour concrete, screed, float, and finish.

FAQs About Garage Floor Slabs
Should I get my garage floor ready for epoxy?
If you plan to apply epoxy, we can pour the slab with a smooth trowel finish (no broom) and avoid curing compounds that interfere with coating adhesion. Let us know your plans upfront for the best result.
