Q. Can you guarantee my concrete will not crack? A. All concrete will eventually crack, it could be within a couple days or years. As concrete dries it shrinks thus causing stress cracks. To control cracking saw cuts are placed throughout the concrete to direct cracking if it occurs. We have found by using rebar and fiber mesh in all our pours that cracking has been very minimum.
Q. How warm does it have to be to pour concrete? A. Broom and Aggregate finished concrete can be poured as long as the ground is not frozen. If the temperatures are above freezing in the daytime but drop below freezing at night, this is not a problem because of chemicals added to the concrete. In some circumstances we use concrete blankets to keep it warm because the concrete itself will generate heat from the chemical reaction of it hardening. For stamped concrete we need to have temperatures above freezing for at least 3 days after the pour.
Q. Do you use rebar in your concrete? A. The standard is to use either rebar OR fiber mesh in concrete to minimize cracking. When we pour a broom or aggregate finished concrete we use BOTH. While many may say this is overkill, the extra cost is negligible and we believe its the best way to do it.
Q. How long does it take concrete to cure and how long before I can walk / drive on it? A. Concrete cures quickly for about 28 days, then very slowly thereafter for years. You can walk on it after 24 hours and drive on it after 7 days.
Q. How long will it take to install my new drive or patio? A. A typical driveway or patio can be completed in 3 days or less. We have a full time crew, and we own all the equipment needed to do your project from start to finish (dump truck, skid steer, compactors, etc). Individuals and small companies that do not have their own equipment and full time employees can take weeks on your project. Once we start on your project, we stay on it until it's complete.
Q. What psi of concrete do you use and how thick is it? A. On a typical driveway and patio we use 3500 psi concrete and pour it 4" thick. Unless you will be driving heavy equipment over the area this is more than enough strength. Recent lab reports from our concrete supplier have shown their 3500 psi mix curing at about 5800 psi around 28 days after pouring.
