Not all concrete slabs are the same — monolithic slabs are poured in one piece, post-tension slabs use steel cables for strength, and waffle slabs use a ribbed pattern for large-span support. Choosing the right type depends on your project, soil conditions, and local building codes. Our slab fundamentals guide covers the basics, while our types guide breaks down when to use each one.
Slab Costs
A concrete slab costs $4 to $8 per square foot for a basic 4-inch pour, with total project costs varying significantly by size, thickness, and whether you need reinforcement or a vapor barrier. Our cost guide provides a full pricing breakdown so you can budget before getting quotes.
Problems & Repair
Slab cracks are common — but not all cracks are created equal. Hairline cracks are usually cosmetic, while structural cracks that widen over time can signal foundation problems. Our crack guide helps you identify the type, understand the cause, and decide whether you need a DIY fix or a professional repair.
