Q. How much does a driveway cost?
A. This depends on many factors. These include: how big the driveway is, how thick the new concrete is to be poured back (either 4″, 5″ or 6″ thick), rebar or no rebar, broom or swirl finish, tooled joints or saw cut, curb grind, rock base, caulk the joints and/or seal the driveway.
Q. How fast can you get the job done?
A. Most residential jobs take less than 2 days.
Q. How long do we stay off of the new concrete?
A. 1-2 days for pedestrian traffic, 7-28 days for car traffic. Concrete is approximately 70% cured in the 1st 7 days and fully cured in 28 days. The longer you stay off of the concrete, the more unlikely it is that the concrete will crack.
Q. What causes concrete to crack?
A. Generally, cracking is caused by poor sub-grade conditions. Either the sub-grade was not prepped correctly or moisture is getting between the sub-grade and the concrete, causing the sub-grade to get soft. Freezing/thawing is another common reason for concrete to crack, not to mention driving excessively heavy equipment on it.
Q. How long should a driveway last?
A. A driveway should last at least 10 years and as long as 50 years. However, several factors can contribute to a shortened lifespan. Some of those include: proper installation, maintenance, having the driveway sealed, caulked joints and washing off road salt in a timely manner.
Q. What are some ways to protect the concrete to help it last longer?
A. Wait as long as you can to drive your vehicle on new concrete. Seal the concrete with a quality penetrating sealer, which repels water and contaminants. Caulk the control joints of the concrete. Control joints are placed to allow the concrete to crack evenly. By caulking the control joints, you’re sealing the joints to help keep water from penetrating the concrete and compromising the sub-grade.
Q. Why pour the concrete 5″ or 6″ thick compared to 4″ thick?
A. The thicker the concrete, the more weight per square inch it will support.
Q. What does rebar do?
A. Rebar, when properly installed, will add extra strength to the slab being poured. However, rebar will not keep concrete from cracking. But, if the concrete does crack, rebar will help the slab stay in tact.
