We put together a list of answers to common questions from customers as well as things you should consider before hiring a concrete contractor. If you don’t see a question here, contact us and we’ll do our best to answer your question.
Can I get an estimate over the phone?
Absolutely. If you know the dimensions of your project, we can generally give you an exact or close estimate over the phone. This also allows you to decide if you want to proceed and have us meet with you for an exact estimate. You can also use our handy contact form to submit your project information.
Why should I use concrete for my driveway if I can get asphalt more cheaply?
First, consider the cost of the driveway over its lifetime. Being in the business since 1952, we have found that our quality driveways last for decades with little or no maintenance. Asphalt driveways need periodic sealing coats to retard age-related cracking.
Even properly constructed, residential asphalt driveways will deteriorate more quickly due to changes in the weather than by residential traffic.
If you consider the cost of surface and crack sealers and the shorter life span of asphalt, concrete costs much less.
What are the lines you cut into concrete?
These lines are called control joints. Control joints are pre-planned cracks designed to accommodate the expansion and shrinkage of the concrete due to changes in temperature and moisture.
Liming Concrete uses hand tools and metal boards to create a straight control joint that is attractive and effective.
Why does concrete crack?
Being an Earthen material, concrete shrinks as it hardens. We place our concrete on supporting soil (crushed limestone) and reinforce it with steel. This prevents the concrete mass from shrinking too quickly. However, concrete always shrinks to the point that it creates internal forces that are greater than the strength of the concrete. Cracks form to relieve those forces.

Does the presence of cracks indicate a structural problem?
In most cases, the answer is no. Hairline cracks in a control joint are normal and do not indicate any structural problem. Cracks that have movement where one side moves independently to the other side should be investigated by a professional.
How long after my job is done can I drive on my new concrete?
In most cases, 6-days of cure time is needed for the concrete to achieve the necessary strength for residential traffic. Cure times may vary depending on weather conditions, thickness and strength of the concrete.
When can I walk on my new concrete?
Typically, concrete will cure enough for foot traffic the next morning.
Do I need to remove topsoil and dirt before placing concrete?
Yes. Dirt and anything organic must be removed before placing concrete. Organic materials are unstable and unable to provide uniform support for concrete slabs.
We use clean limestone that provides uniform support and also allows water to pass through the base without washing it away.
Also, and just as important, the water is kept away from being directly below the concrete where freezing and thawing can move the ground.
At what temperature can concrete be poured?
Concrete can be poured year round. We pour concrete without reservation when the daytime temperature is 40 degrees and above.
