A Concrete Inc has the capability to pour all year around.
Due to expansive soils the minimum thickness is 4”. Though, depending on the weight to be applied to a slab, can be any thickness.
YES, ALL CONCRETE CRACKS! This is due to the evaporation of water coming out of the concrete mixture as it cures. This is not a reflection of poor workmanship.
Controls joints are intentional lines placed in the concrete to weaken the slab and help guide the cracks to follow in a straight line along the joint line. This is an attempt to help prevent random cracking, but not all cracks will crack in a straight line or follow the joint line.
In most general situations, the following day you can walk on the concrete without damage. However, depending on weather conditions and some other variables it can length or shorten this amount of time.
Most driveways that are 4” thick need a cure time of 7 days before it can be driven on. Although different concrete mix designs can be used to decrease this timeframe to 12 hours, if needed. These mix designs are called, 12-hour mix, 24-hour mix and 48-hour mix.
Most driveways can be torn out and replaced within one day.
They should be sealed with a concrete caulking called Sikaflex, which is self-leveling material that is placed in the control joint.
Magnesium Chloride causes your driveway to spall or chip away. When pouring new driveways, a chemical called AE3, which anti-spalling chemical can be added to the mix design to prevent this chemical from causing spalling damage.
Clear seal should be applied as needed. Typically, the first application should be applied 28 days after the pour and then again, the following year. If proper snow removal is done throughout the winter months, a seal should be only be reapplied every 3-5 years.
Properly maintained concrete should last 50 years
