​Types of Concrete Damages

• Cracks: When should you be concerned about a crack? Generally speaking, you might want to intervene by repairing, resurfacing or replacing if the crack seems to allow water to get underneath the pad, which will worsen the damage. The crack is becoming a safety hazard to your commercial or residential property. Wide cracks in concrete are best patched and sealed with a concrete patching compound. Smaller cracks can be repaired with a concrete caulk or liquid filler. Patching compounds typically are mixed with water and applied with a trowel.
• Spallinging:Spalling, or pitting, is the chipping or flaking that occurs on the concrete’s surface when it’s exposed to freeze-thaw cycles or improper mixing. Freeze-thaw occurs when water gets into the pores, and then freezes and expands. Some of the most common signs and symptoms of spalling on concrete surfaces include striated lines, discoloration, and a pitted or rough appearance and texture. You can depend on us to not create that problem but here our San Jose Contractor Pros will walk you through all the criteria & steps to get the spalling out of your concrete.
• Settlement: When voids form under a concrete pad, the concrete tends to crack, break, and settle into the void. The result is an uneven and unstable surface that likely requires quick action before even larger damage can occur. Typically form through some type of issue with the soil, such as it being loosely compacted at the time of pouring, there being a severe drying and shrinking of the soil or water leakage. To repair concrete settlement mudjacking would be one of our services to help fix and stop the hazards it's bringing to your concrete, mud jacking can lift a settled concrete slab by pumping a grout through the concrete and pushing it up from below.
• Lifting/ Unleveled: Concrete lifting is bringing a concrete slab back up to its original position by filling the ground beneath it. There are two methods, mudjacking and slabjacking. Both are cheaper and faster than tearing out and replacing the concrete. Severely lifted pads deserve immediate attention as they can be considered a safety hazard for pedestrians and individuals in wheelchairs, and can sometimes even cause damage to vehicles driving over it. And this really applies for both Lifting and Leveling Concrete. You'll need to use mudjacking or slabjacking for either one.
