Answers to commonly asked questions from the experts on HomeGuide.
How much does pouring concrete cost?
Pouring a concrete slab costs $6 to $12 per square foot, depending on the thickness, size, and purpose. Concrete patios are typically 4 inches thick and range from a basic broom-swept finish to complex colors, stamping, and designs.
Concrete slab garage floors, driveways, and foundations are typically 6 inches thick and require wire mesh or rebar reinforcement to make sure it's durable enough to withstand the weight of heavy vehicles or a house.
What does a concrete contractor do?
A concrete contractor builds or repairs concrete driveways, concrete foundations, concrete slabs and patios, concrete sidewalks and steps, walls, and other concrete work. Concrete pavers handle every step of the process, from site preparation to mixing and pouring the concrete. Concrete driveway contractors also provide concrete resurfacing or leveling.
What is a concrete slab?
A concrete slab is a flat, horizontal surface area that's used to pave outdoor areas or support the weight of vehicles or buildings. Most homeowners use poured or pre-cast concrete slabs for:
Patios
Driveways
Home foundations
Garage floors
How long does concrete last?
Concrete slabs, floors, and stairs typically last 30 to 50 years or over100 years if properly sealed and maintained. Concrete cracks and may not last as long in cold climates where the ground freezes regularly. Driveways and patios are exposed to the elements and typically have shorter lifespans than foundations or garage floors that are more protected.
When should I replace a concrete slab or floor?
Small cracks or small damaged areas can be repaired or resurfaced for less than a full replacement. However, you should consider replacing concrete if it is over 40 years old or if you notice:
Major cracks
Crumbling
Sinking edges
Warping or potholes
Pooling water or poor drainage
How long does concrete take to dry?
Poured concrete dries in multiple stages: After 1 to 2 days, it's dry enough for a person or pet to walk on it without leaving footprints. After 1 to 2 weeks, you can drive on concrete. After 28 to 48 days, the concrete is completely dry and considered fully cured.
Can I pour a concrete slab myself?
You can pour a small concrete slab yourself as long as you plan and prepare. Concrete is difficult and costly to remove once it sets if not done properly, so be sure to take the proper precautions:
Make sure you have enough concrete before starting.
Measure and install your form carefully.
Wait until the weather is dry and warm before pouring.
Remove grass and vegetation before starting.
Coat the wooden for with oil or a concrete release agent for easy removal.
What's the difference between cement and concrete?
Cement and concrete are often used interchangeably, but they’re not the same thing. Cement is made mainly of limestone and is an ingredient in concrete. Concrete is a mixture of roughly 10% cement, 20% water, 30% sand, and 40% gravel.
