Concrete is a durable and reliable material, but it may eventually become uneven or sink as a result of various factors such as a sinking foundation, moisture fluctuations, and soil erosion. Tripping risks, dangerous and visible cracks, and a general deterioration in structural integrity might result from this.
Mudjacking concrete is a common and reasonably priced way to repair uneven or sunken concrete. However, what is mudjacking, and how does it work? We’ll go over all you need to know about this efficient concrete repair method in this guide.
What is Mudjacking Concrete
Mudjacking concrete is a technique used to elevate and stabilize uneven or sunken concrete surfaces. The process involves injecting a specially made cement mixture, also known as “mud,” under the damaged concrete slabs. Usually, a combination of cement, water, and occasionally additional ingredients to improve stability makes up this composition.
The slab is progressively raised back to its initial position as the injected grout fills in the spaces underneath it. After the slab is level, the grout solidifies and gives the concrete long-lasting stability, preventing additional sinking or movement.
How Does Mudjacking Concrete Work
Mudjacking typically involves the following crucial steps:
Site Inspection: A qualified contractor will evaluate the concrete slab’s state and decide whether mudjacking is the best course of action. They will examine whether soil erosion, moisture, or other variables are responsible for the sinking.
Drilling Tiny Holes: Small holes are drilled into the sinking slab, often measuring between 1.5 and 2 inches in diameter. These holes will act as the grout mixture’s entry sites.
Injecting the Mixture: The mortar mixture is injected under the concrete slab using a pump. As the mixture fills in the gaps, the slab gradually starts to rise to its proper level.
Leveling and Monitoring: To make sure the slab is rising uniformly, it is constantly observed as the grout is injected. The holes are sealed after the level is attained.
Waiting: The grout will solidify over the next few hours following the injection, thereby stabilizing the slab and preventing further sinking.
When to Use Mudjacking Concrete
Mudjacking is an ideal fix for a number of typical concrete problems:
Sunken Concrete: Mudjacking can be used to raise and level a concrete surface that has settled unevenly.
Uneven Driveways & Sidewalks: Mudjacking works particularly well for fixing uneven and cracked roads and pathways, which can cause trips and falls.
Pool Decks: Mudjacking can stabilize pool decks that may shift over time as a result of soil erosion.
Basement Floors: Mudjacking can help level basement floors without replacing them completely, since shifting soil or moisture issues can cause them to sink.
Limitations of Mudjacking Concrete
Although mudjacking has many advantages, it isn’t always the ideal technique to deal with concrete issues. Among the limitations to consider are:
- Not Effective for Severe Damage
Mudjacking might not be able to return the concrete to its original state if it has significant cracks or damage. In these situations, replacement can be required.
- Soil Conditions
The restoration may not be as long-lasting if the soil is extremely unstable or prone to erosion.
- Restricted to Specific Concrete Types
Mudjacking works well on concrete slabs, but it may not be suitable for fences or steps.
