AJ’s Concrete takes all important measures to prevent our concrete from cracking; however, there is no way to guarantee that cracks won’t appear at some point. Control joints are installed in the most vulnerable spots, which is where we want cracking to occur. A crack of around three sixteenths of an inch or less is what you can normally expect.
Colours / Discolouration
Although we are skilled at matching up colours, we cannot guarantee an exact colour match. Mixing the colours are not always going to be precisely the same each time, meaning even within your driveway some areas will have a minor variation in colour, which will likely fade over time.
It’s extremely common for driveways or garage floors to shift over time, but it is not a cause for concern. Below our compacted sand layer, the sub grade movement is beyond our control. This movement is what creates shifting in the concrete, and is something we cannot predict or prevent.
Concrete is subject to various harsh weather elements in our climate. Outdoors, it faces, ice, salt, vehicle traffic and other damaging situations. A small amount of stones popping out of the concrete and flaking can occur in a normal situation. This will not affect your concrete. If excessive amount of flaking occurs, this could be a sign of a problem.
Texture will vary from job to job, conditions, staff, etc. An exact texture cannot be guaranteed.
If you have hollow sounding concrete when you tap on it, this can occur because pipes or other things are located under the floor. This is a normal occurrence and is not cause for concern.
Our main concern for your driveway is the use of salt in the winter time. People often unknowingly use salt on their driveways to remove snow and ice, but this can be very damaging to newer concrete. Vehicles also carry salt from the city streets onto your driveway and deposit it onto the concrete, corroding the surface. Please be mindful of this and take the necessary steps to prevent salt from ruining your beautiful driveway. The first year is the most important to avoid salt contact. As years go by, your concrete will continue to cure and will be less susceptible to this damage.
We recommend that you also keep your driveway free from corrosive fertilizer for the same reason.
