WHAT CAUSES CRACKS IN A DRIVEWAY?
Everyone notices cracks in their driveway. Weeds pop up and anthill mounds spill out of the crevices. Most driveway cracks are small and considered non-structural, but cracks with wider openings and heaved edges can be trip hazards and should be repaired.
A driveway or walkway can crack for several reasons:
•Tree roots can push up under a driveway and cause heaving, but they can also cause cracking and a downward movement of the slab from excessive moisture some trees remove from the soil under the area.
•Soil erosion is the slow washing away of soil on a sloped site due to rainwater flow from a higher level down to a lower elevation. It is often more pronounced near creeks and rivers because water is also moving under the soil toward the lower levels.
•Excessive weight placed on a driveway slab, especially at outside corners, will cause settlement and cracking—like in the photo at the top of this page. An example would be a concrete or septic pumping truck with one set of wheels on the slab and the other set on the ground.
•Sinkholes can also cause driveway damage. While rare, they do occur. Not all sinkholes are as dramatic as the ones in the news that swallow up a house overnight. Many start out as a small depression in the soil that grows over time until a collapse occurs.
•Clay soil has an elasticity that causes it to shrink during dry spells, then swell during seasons with heavy rains. The swell/shrink cycle causes the ground under a driveway built over a layer of clay soil to heave up and down in seasons that are extra wet or dry.
•Poor site preparation can cause driveway cracking in the first couple of years after construction, typically due to inadequate soil compaction before placing the concrete.
Concrete is strong in compression because the small and large aggregate stones in the mix can carry large loads. However it is weak in tension (bending). To offset this weakness, steel is added for strength. In the case of a driveway it would be a light gauge steel mesh embedded in the slab at the time the concrete is placed. Glass, steel or plastic fibers can be added to the concrete mix for added tensile strength. A concrete slab shrinks slightly during the curing process in the first couple of months after it is placed, and most driveways and walkways are scored to encourage the hairline shrinkage cracks to happen in the notched lines, where they are less noticeable. source: mcgarryandmadsen.com
