Concrete Slabs & Pads in St. Louis
A slab should be designed for what it will support. A small shed pad, hot tub base, detached garage floor, and equipment slab may need very different thickness, reinforcement, edges, and approvals.
Tell the contractor the future load
Share manufacturer specifications, structure dimensions, anchor locations, point loads, utilities, and whether the slab will be enclosed. Do not rely on a generic “four-inch slab” description when the supported use has structural requirements.
Coordinate before placement
- Confirm final size, elevation, orientation, and access.
- Plan electrical, plumbing, drainage, sleeves, and anchors before the pour.
- Clarify base, reinforcement, thickened edges or footings, and finish.
- Verify setbacks, permits, and association rules for the structure—not only the concrete.
Hot tubs and heavy equipment
Filled weight, manufacturer support criteria, electrical clearances, drainage, and service access should be known before the pad is designed. Ask the equipment supplier and local authority what documentation is required.
Frequently asked questions
Does a shed slab need a permit?
Requirements may depend on slab size, the structure placed on it, utilities, setbacks, and local rules. Check the complete project, not just the concrete.
Can utilities be added after the pour?
Sometimes, but sawcutting or surface-mounted routes can be costly or unattractive. Coordinate sleeves and penetrations before concrete placement whenever practical.
