Helical Piers – Helical piers are metal rods that are screwed into the ground to provide support for the foundation or slab. They are used to stabilize and lift sinking foundations and slabs. Helical piers are a good option for homes with severe foundation or slab issues or where the soil is particularly unstable. They provide a permanent solution but can be more costly and invasive than other methods. Additionally, the installation of helical piers requires specialized equipment and expertise, making it essential to work with a qualified professional if you choose this option.

Mudjacking – Mudjacking involves lifting a sunken concrete slab by pumping a mixture of water, soil, and cement underneath it. This mixture fills the void and raises the slab to its original level. Mudjacking is typically less expensive than injection pier installation and can be completed quickly. However, it may not be as effective for deep or extensive voids, and the results may not be as long-lasting. Additionally, mudjacking may not be suitable for all types of soil conditions, making it a less versatile option compared to injection pier installation.

Polyurethane Foam Injection – This method uses a polyurethane foam that expands to fill voids and lift the foundation or slab. The foam is injected through small holes drilled in the concrete. Polyurethane foam injection is less invasive than other methods and cures quickly, allowing for immediate use of the repaired area. However, it can be more expensive than mudjacking and may not be suitable for all types of soil conditions. Additionally, the long-term effectiveness of this method can vary, making it important to consider the specific needs of your property before choosing this option.
