When Does Your Property Need Concrete Repair?

Although concrete is a long-lasting, durable material that's commonly used for construction-related purposes, the durability of it is highly dependent on the stability of the foundation below it. If steps, patios, sidewalks, porches, and interior slabs become unstable below the surface, concrete can settle. If you are experiencing this problem, it’s important to contact an experienced contractor that can provide concrete leveling services. Get your concrete repair needs with help from Keystone Foundation Repair.

Where Does Concrete Slab Settlement Occur?

Concrete slab settlement tends to occur in areas where the distance between the concrete slab and the soil is minimal. Both exterior and interior slabs can be affected by settling that occur in these areas. There are four common reasons why a concrete slab may settle:

  • Soil drying and sinking
  • Washout of soil under the slab (usually caused by leaking pipes)
  • Poor compaction fill soil
  • Upward movement of the foundation or slab

How Do We Fix the Problem? - Concrete Slab Leveling with Mud Jacking

Our approach to dealing with concrete slab settlement is a process referred to as "mud jacking" or "slab jacking." It's a method that involves pouring or pumping a mixture of water and cement under an existing slab that's damage or uneven to make the surface flat again. Mud jacking can be used on any cement slab to produce a permanent repair. Holes are drilled into the slab around the base and the mixture is inserted through the holes to lift up the concrete to restore the proper height. The mud jacking process is executed by doing the following:

  • 1” holes are drilled at approximately 3’ centers
  • The pulverized limestone material is pumped. It fills the void beneath the slab and then lifts the slab back into place
  • The small 1” holes are patched with a non-shrink grout mixture

Common Hazards from Concrete Slab Settlement

Concrete slabs naturally settle over time. This process becomes an issue when concrete surfaces begin to sink and shift. Issues with water seepage, faulty drainage, poor compaction, and damage from seasonal freeze-thaw cycles can also create a void in concrete between the surface and the base. If you have problems like this around your home or business, you may also have potential slip-and-fall hazards. Uneven concrete can also:

  • Affect your property's value
  • Subject you to the risk of legal action if someone falls on your property
  • Contribute to problems that may make concrete unrepairable
  • Damage other parts of your property
  • Increase your risk of having related water damage
