Concrete is used all over the place, and for good reason: it’s strong, durable, and looks great. However, it isn’t invincible, and sunken or uneven concrete can be a tripping hazard and aesthetic concern.

Leveling is a repair technique that lifts concrete slabs back to their proper positions, improving safety and curb appeal simultaneously. This guide will introduce you to the basics of concrete leveling and various methods available. Contact Concrete Leveling Dallas now!

Mudjacking is a method of concrete leveling that uses a mixture of sand, cement and soil to lift sunken concrete slabs. This mixture, which is also known as a slurry, is pumped through holes that are drilled into the sunken concrete. When mudjacking is performed, it can lift and stabilize a concrete slab that has sunk due to the ground deteriorating beneath it. The slurry fills in gaps or voids in the foundation of the slab, and the pressure from the pumping process lifts it back up to its original position.

Mudjacking can be used to repair sinking or uneven concrete sidewalks, driveways, pool decks, patios, and floors. Uneven concrete surfaces are not only unsightly and can create tripping hazards, but they can also be structurally unstable. They can cause damage to the foundation of a home or commercial building and may be in danger of sinking further if left unattended.

Unfortunately, mudjacking is not a long-term solution for sagging or uneven concrete slabs. This is because the slurry used in mudjacking can break down from exposure to water and freeze-thaw cycles. Additionally, slurry is not waterproof, so it can leak into the concrete and surrounding structures when it is wet.

Many experts recommend avoiding this form of concrete leveling and opting for a more modern alternative, such as polyurethane foam injection. Mudjacking is a time-consuming and labor-intensive process, and it can be difficult to perform correctly.

The slurry used in traditional mudjacking is highly pressurized, which can be difficult to control and lead to overdoing the job, making it more expensive and time-consuming than it should be. Additionally, it can be difficult to spread the slurry evenly across the entire void under the slab. This can lead to weak spots in the concrete that are prone to cracking and breaking down over time. Polyurethane foam, on the other hand, is injected at a lower pressure and can be spread more evenly throughout the void under the slab. This leads to a faster and more affordable concrete lifting solution. In addition, polyurethane is waterproof, so it can protect the concrete and underlying structures from water penetration.

Polyurethane Foam Injection

A concrete slab that’s become uneven can be repaired quickly using polyurethane foam injection, a process that doesn’t require digging up the concrete. In fact, the repair can be completed in a matter of hours. This method is also over 80% quicker than traditional mud jacking methods, saving you money and minimizing disruption to your home or business.

While mudjacking utilizes heavy cement to lift a sinking concrete structure, the polyurethane injection process relies on dense, durable polyfoam. During the injection process, the polyfoam expands to fill voids and level concrete. The material is similar to shaving foam, but it dries into a solid substance that’s much stronger and more powerful than the styrofoam used in packaging electronics for shipment.

The injected foam is impervious to water, preventing further damage to the underlying soil and eliminating future settlement issues caused by moisture infiltration. The material is able to support extremely heavy loads, making it ideal for applications such as raising sidewalks and driveways. The injection process is also significantly cleaner than mudjacking, eliminating the need for excavation and reducing environmental impact.

The foam is injected through small holes that are drilled in the affected concrete area. The resulting voids are then filled with the liquid, expanding and restoring the structural integrity of the slab. Once the voids are filled, the technicians grout the small holes, which can be done immediately after the injection. The high-density polyurethane will harden and set in a matter of minutes, allowing the slab to be fully used shortly after the procedure is complete.

Unlike mudjacking, polyurethane is free of CFCs and HCFCs. It is also odorless, resistant to mildew, and stable against tree roots. Because of its ability to withstand the weight of vehicles and people, it is also an ideal option for lifting and stabilizing airport runways. This material is also ideal for leveling concrete walkways, patios, and driveways as well as sealing cracks and improving the energy efficiency of the structure. It can even be used to level concrete for bridge decks and roadways. Its durability and speed make it an attractive alternative to more costly replacement options.

Stone Slurry Grout Leveling

Concrete is one of the strongest and most durable building materials around, but it’s not indestructible. It’s subject to a lot of wear and tear over time, which is why it’s important to seek concrete repair services as soon as you notice sinking or uneven concrete surfaces. These repairs are relatively quick and cost-effective, and they’re a great option for avoiding further damage and eliminating dangerous trip hazards from your property.

Depending on the severity of the issue, different methods of concrete leveling may be appropriate for your property. For instance, small surface-level cracks might only need cosmetic repairs, while severely damaged or crumbling concrete could require replacement. A professional will evaluate your concrete to determine the best solution for your home and budget.

Mudjacking is a method of concrete leveling that uses a mixture of crushed stones (primarily limestone) and water to lift sunken concrete. The process is complex, and it’s not recommended that homeowners attempt this DIY project without the proper knowledge and tools. Not only can mudjacking damage the existing concrete, but it can also cause additional structural issues with the surrounding soil.

Polyurethane foam injection is a modern concrete leveling technique that can be installed quickly and effectively. During this process, penny-sized holes are drilled into the sunken concrete. A specialized tool is then used to inject the polyurethane foam, which fills the crevices and voids beneath the slab and presses it back into place. The foam is able to cure within about 30 minutes and offers incredible strength for the concrete, while being environmentally friendly.

Leveling is more affordable than replacing the entire slab, and it’s much quicker. The repair method also eliminates the need for tearing out and disposing of old concrete, which is good for the environment and cuts down on construction waste. For these reasons, it’s often considered a more sustainable solution than concrete replacement.

Consult a Professional

Concrete is a popular construction material for a reason: it’s durable and versatile. But even the strongest concrete is susceptible to damage, and this damage can lead to sinking, unevenness, and tripping hazards. Fortunately, these problems can be fixed with concrete leveling, which lifts sunken concrete back to its original position and improves safety, functionality, and aesthetics. However, it is important to consult with experts to determine whether this repair method is appropriate for your home.

Uneven concrete surfaces can cause serious harm to your property, both structurally and financially. They can also present a tripping hazard, especially for children and elderly individuals. Regularly traversing uneven surfaces can also damage vehicles, leading to costly repairs down the line. Concrete leveling techniques, such as PolyRenewal, are a cost-effective solution that can solve these issues and restore your concrete surfaces to their original condition.

While concrete leveling can be effective, it is important to know its limitations. This type of repair is best suited for small to medium cracks that have not yet grown wider. However, if the cracks have grown larger, you should consider calling in a professional for an inspection. If your concrete has sustained severe damages, such as large voids or complete collapse, it is likely not salvageable with leveling methods.

The cost of concrete leveling can vary greatly, influenced by the size of the area, the severity of the damage, the chosen repair method, and the scope of the work needed. It is best to obtain estimates from reputable companies that will perform a thorough inspection and provide a quote tailored to your specific repair needs.

Having your concrete repaired by professionals is an affordable and quick option to fix uneven or sinking surfaces, such as driveways, sidewalks, pool decks, and patios. Compared to replacing the entire slab, concrete leveling is an affordable and more efficient repair approach.
