The most common questions homeowners in Maryland, Delaware, New Jersey & Pennsylvania ask — answered honestly

Concrete slabs are the foundation of countless residential projects — shed bases, AC equipment pads, garage floors, additions, and more. Yet most homeowners have surprisingly little information about what makes a slab perform well or fail early. All About Construction LLC answers the questions we hear most frequently.

Q: What thickness do I actually need?

For pedestrian-only applications (walkways, patio areas with furniture): 4 inches is standard. For vehicle areas (driveways, garage floors): 5-6 inches minimum, with rebar. For heavy equipment or structural applications: engineer’s specification required. Many installations fail early simply because they were poured too thin for their actual use.

Q: Do all slabs need rebar?

Not all — but more than most homeowners think. Shed slabs in good soil with proper sub-base can often perform well with fiber reinforcement or welded wire mesh. Vehicle and structural slabs should always have rebar. When in doubt, include reinforcement; it costs a fraction of the slab replacement cost if it turns out to have been needed.

Q: What is a proper sub-base and why does it matter?

The sub-base is the compacted gravel layer below the concrete. It distributes load, resists frost heave, and provides drainage. An inadequate sub-base is the number one cause of premature slab failure in our region. All About Construction LLC never skips this step.

Q: How long until I can use the slab?

Light foot traffic: 24-48 hours. Furniture and normal use: 7 days. Vehicle traffic: 28 days for full design strength. These timelines assume proper curing conditions.

Q: Do I need a permit for a concrete slab?

Depends on your municipality. Slabs under a certain size typically don’t require permits. Structural slabs, foundation work, and anything over a threshold square footage usually do. All About Construction LLC researches permit requirements for every project. Contact us — we’ll handle it.
