First of all, we're in the business of repairing concrete and leveling foundation repair Knoxville. That includes slabs and foundations, pools, sidewalks, driveways and everything else in between. Another term used to describe what we do is "Slab jacking". Here's a little background info on how it works.
All concrete - even reinforced concrete slabs- can settle due to soil erosion, compaction, and the settling that results. This can wreak havoc on structures. It can cause slabs under houses to settle and thus damage the house. Sidewalks can settle creating cracks and uneven walking surfaces. Driveways can also be damaged from years of freezing and thawing, causing them to buckle and crack.
In the past the only solution was to replace the damaged area or try a temporary patch. Replacement is often extremely expensive and time consuming. Patching is seldom permanent. Our team now works with the latest lifting technology: a hydraulic process. First we drill a hole in the affected area then we inject a special slurry of cement that quickly fills the voids under the sunken area. The hydraulic pressure pushes the concrete upwards, eventually raising it to its original level. The repaired result is a permanent solution that gives the concrete a solid foundation, thus stopping it from settling.
Below are some examples of what we can do. Whether you have a cracked sidewalk, driveway, or a sunken slab, we can easily restore your damaged concrete to like-new condition, often in under a day.
In this job we repaired a severely damaged driveway. Huge sections of concrete were cracked and sunken. We raised and leveled all of the damaged pieces and sealed the cracks with an elastic sealant that gives and takes with hot and cold weather, ensuring cracks won't reappear.
Cracks in sidewalks can create a serious tripping hazard not to mention pose a liability. This sidewalk had cracked in one section and sunk 2 inches. We raised, leveled, and sealed the damaged area. Once cured, it'll be hard to tell there was ever any damage.
Shown here is some serious settling in the slab in this carport. As seen by the door pictured the slab had sunken 5"-6". We were able to bring the entire slab back up to its original level. This also stopped water from collecting against the house during rain storms.
This driveway was rendered almost entirely unusable with numerous areas where the whole driveway was severely settled. No problem. The whole driveway was torn apart and removed so that we could lay down a long-lasting concrete driveway.
Our goal is to set the standard for the rest of the industry to follow and lead by example.

This method utilizes concrete cylinders that are approximately 12 inches long by 6 inches in diameter. There are two basic types of cylinders, some are solid and some have holes through the centers from end to end.
There are companies that claim that placing various materials in the center holes makes the piers more effective. They have even patented the process of placing different materials in the core of the piers to gain a marketing advantage.
Others point out that leaving a void at the core of the pier weakens it making in susceptible to crushing under the weight that is used to press it into the ground. The bottom line is that there are structures that are supported by hollow and solid concrete piers that are lasting and performing equally well.
Installation consists of digging holes next to the foundation in the areas where piers are required to allow access directly beneath the foundation. A hydraulic press is then used to press concrete cylinders into the soil directly beneath the foundation using the full weight of the foundation and the structure it supports.
The cylinders are pressed one on top of the next until they refuse to move any further. This process is continued until all piers are installed. Next the foundation is raised simultaneously in multiple locations and a cap and shims are placed on top of each pier and then the weight of the foundation is allowed to rest on the piers.
Pressed concrete piers are effective in almost every situation because they do not depend on reaching bedrock, instead they are supported by skin friction. That is the friction between the surface of all cylinders and the soil that surrounds them.
Imagine that you are holding a rope tied to a heavy weight. You can lift a limited amount of weight by gripping the rope with your hands. You are creating skin friction between the rope and your hands. If you have a friend to help you can probably lift twice as much. What if you have 5 or even 10 or 20 friends to help?
This method is very effective because the weight of the structure is carried by multiple piers with each pier supporting only a fraction of the weight that was used to press it into the ground.
This is the preferred method of foundation repair by most major foundation repair companies including East TN Concrete Lifting. The disadvantages mentioned above are really not a problem if you choose a reputable contractor who does proper cleanup and saves and replaces all shrubbery.
This method uses a drilling system to drill a hole with a flared bottom. This hole is then filled with steel reinforced concrete. The concrete is allowed to cure for two weeks or more and before the weight of the foundation can be supported. This method is also used in new construction to provide support of a foundation before it is poured.
This method can work well for new construction however since the depth that this type of pier can reach is limited it's effectiveness is also limited to only those situations where it's reach is below the soils causing the problem. It is also somewhat expensive as compared to other methods.
