Demystifying Concrete Lifting: A Comprehensive Guide

Concrete lifting, also referred to as slab jacking or mud jacking, offers a cost-effective and efficient remedy for rectifying uneven or sunken concrete surfaces. This method not only restores the structural integrity but also enhances the overall aesthetic appeal of the concrete. But how does it work? Dive into the process.

Understanding the Problem

Before getting into the solution, it's important to understand why concrete sinks in the first place. The main culprit is often soil instability. Over time, soil can compress, shift, or erode, creating voids beneath the concrete. When these voids become too large, the concrete can't support its own weight and starts to sink.

The Concrete Lifting Process

The concrete lifting process is actually quite straightforward and involves just a few simple steps. First, the affected area is carefully inspected to assess the extent of the damage and determine the appropriate lifting technique. Then, small holes are strategically drilled into the concrete surface. Next, a specialized mixture is injected into these holes, which expands and lifts the concrete to its original position. Finally, the holes are filled, and any visible signs of repair are touched up to ensure a seamless finish.

Step 1: Drilling Holes

The process begins with drilling small holes through the sunken concrete slab. These holes serve as entry points for the lifting material.

Step 2: Pumping the Material

Next, a special mixture, often comprised of cement and soil, is pumped through the drilled holes. As this mixture fills the voids beneath the concrete, it starts to exert an upward pressure on the slab.

Step 3: Lifting the Slab

As more material is pumped in, the slab slowly rises until it reaches the desired level. The lifting can be controlled with precision, ensuring the slab is perfectly aligned with the surrounding concrete.

Step 4: Sealing the Holes

Finally, once the slab is back in place, the drilled holes are sealed off, leaving a smooth and even surface.

The Advantages of Concrete Lifting

Concrete lifting is widely favored as the go-to solution for rectifying sunken concrete owing to its multitude of benefits and advantages.


Compared to replacing the entire slab, concrete lifting is much more affordable. It uses the existing concrete, which means there's no need for new materials or extensive labor.

Quick and Easy

The entire process can often be completed in just a few hours, and the concrete is ready to use almost immediately. There's minimal disruption to daily life.

Environmentally Friendly

Repairing instead of replacing a damaged concrete surface reduces waste and conserves resources. It's a greener solution for sunken concrete.

Concrete lifting is a practical and efficient method for fixing uneven or sunken concrete. With its straightforward process and numerous advantages, it's no wonder this technique is popular among homeowners and businesses alike. So next time there's a dip in the driveway or a sag in the sidewalk, consider concrete lifting—it could be the perfect solution.
