Mud Jacking involves injecting a mixture of water, soil, sand, and cement beneath the concrete slab. There are two main options for slab jacking repairs: mud jacking or foam jacking.

However, this option can be costly in both time and money, as the old slab must be removed and hauled away before a new slab can be prepped for and poured.Ī more cost-effective option is simply having the cracked concrete slab repaired via slab jacking. The option that comes to mind first for many people is simply replacing the cracked slab. There are a few options available for concrete sidewalk repair. Thankfully, as much as we can rely on concrete sidewalks eventually cracking, we can also rely on solutions. Repairing Cracked or Damaged Concrete Sidewalks Incorrectly blending the concrete mix and an improperly cured slab can cause a faster breakd own of the concrete, again resulting in cracks, breakage, or sunken slabs. For example, if the contractor did not properly prepare the soils that lie beneath the slab, voids in the soil may develop quicker and result in a cracked or sinking slab. These issues can also be the result of poor construction practices. In the case of concrete sidewalk slabs, this means cracks, sinking, and breakage. Long-term exposure to just about any kind of weather will eventually cause materials to break down. Climates that typically experience high levels of moisture due to rain, humidity, or frequent freeze/thaw cycles are even more susceptible to concrete cracks. Weather tends to be responsible for most issues regarding construction, especially when it comes to concrete. While these intentional cracks ensure resistance to weather-related stress and potenti al damage, concrete slabs will eventually develop cracks or other damage over time. These cracks are carefully and evenly spaced before the first drop of wet concrete is poured and will help ensure the sidewalk is resistant to weather-relate d expansion or contraction. To avoid these problems, a contractor pours a sidewalk as multiple individual slabs with pre-planned cracks. These problems are, of course, undesirable and can pose a serious safety risk. If sidewalks are poured as a single continuous slab, they are practically guaranteed to develop problems such as cracks, buckling, and breakage.
Most sidewalks feature intentional cracks to allow concrete slabs room to expand and contract due to weather. Here we explore the difference between intentional and unintentional cracks in concrete sidewalks and what you can do to take care of your concrete sidewalk slabs. When you own property, it’s a good idea to get wise about concrete cracks.
