The Ins and Outs of Concrete Repair
Concrete may be durable, but it has limits. Cracking, uneven distribution, and even sinking occur, often because of “voids” in the soil underneath. When a void causes damage, repairing cracks will repair the damage.
These are subterranean zones where the soil is less suited to supporting soil compacted beneath the concrete. Many things cause voids that include:
- Underground water dissolving limestone, leading to soil collapse.
- Improper soil compaction before the concrete was added.
- Loss of support due to construction or excavation efforts in neighboring areas.
Voids can be diminished by draining and thoroughly compacting soil before adding the concrete. Unfortunately, voids are not always unpreventable.
Concrete does well against compression but terribly against tension. Pre-stressed concrete, reinforced with rebar, is intended to counteract concrete’s failings at surviving tension. While this helps, some limits and cracks emerge upon breaking those limits. You can repair concrete damage with concrete crack repair epoxy.
Repairing cracks is not as easy as filling them. Just filling your cracks does nothing to stop them from reopening while the concrete further seeps into the voids.
Properly filling voids is known as “mud/slab jacking.” This procedure has the repair inject concrete repair products directly into the voids to provide density to the soil, allowing it to better support the concrete, fill the void, lift and straighten concrete, and stop further collapsing of the soil. There are two types of repair.
- “Mud” grout is a loose blend of water, cement, and aggregate.
- Polymer grout is an expanding foam. It cures quicker than mud grout and can be added to even moist soil.
