Frequently Asked Questions

What should you look for in a concrete contractor?

When looking for a concrete contractor, it’s important to consider the contractor’s experience and references. The contractor should be able to provide a portfolio of their work and a list of references. It’s also important to ask the contractor about their insurance and bonds.

The contractor should have general liability insurance and workers’ compensation insurance. The contractor should also be bonded. This protects you in the event the contractor doesn’t complete the project or doesn’t do quality work.

What’s the most common type of concrete?

The most common type of concrete is standard ready-mix concrete that’s delivered to a construction site by truck. The truck mixer mixes the ingredients together and discharges the concrete into a chute that feeds into a formwork system.

The formwork provides the shape and size of the finished concrete, and the concrete cures over time. Ready-mix concrete is often used for larger projects such as bridges, buildings, and highways because it can be produced in large quantities and is easy to work with.


By asking yourself these questions, you can be sure you’re hiring a reputable, qualified contractor who’ll do a great job on your concrete slab project. Get several bids before making your final decision, and don’t be afraid to ask for references or proof of previous work. Doing a little due diligence now will pay off in a job well done later.
