What separates a 35-year concrete job from a 12-year one
Concrete is sold by the cubic yard, but installed by the inch. The same concrete truck can pour two slabs that look identical on day 1 — one will last 35 years and one will be cracked and spalling by year 12.
Three details make the difference:
- PSI rating. 3,000 psi is the bare minimum residential mix. We pour 4,000 psi as standard — 33% more cement, significantly better longevity in Florida’s heat-rain cycle.
- Reinforcement. Fiber mesh (not just air-entrained concrete) controls microcracking. Rebar grid for heavy-load applications. The right reinforcement adds $0.30–$2 per sq ft and is non-negotiable.
- Control joint spacing. Joints cut every 8–10 linear feet give the slab a planned place to crack. Joints spaced too far apart (15+ ft) force the slab to crack randomly, which it will, within 3–5 years.
