Mudjacking Foundation Repair Mobile Alabama
Mudjacking foundation repair, also known as slabjacking, is a specialty concrete repair technology. In essence, slabjacking attempts to lift a sunken concrete slab by pumping a grout through the concrete, effectively pushing it up from below. The process is also commonly referred to as “mudjacking” and “pressure grouting” as well.Accounts of raising large concrete slabs through the use of hydraulic pressure date back to the early 20th century. Early contractors used a mixture of locally available soils (sometimes including crushed limestone and/or cement for strength), producing a “mud-like” substance and thus the term “mudjacking.” Modern slabjacking contractors can now use an expanding polyurethane foam, providing a multitude of benefits when compared to traditional slabjacking materials.
The slabjacking process generally starts with drilling small diameter access holes in the concrete, strategically located to maximize lift. These holes are generally 3/8″ or 5/8″ diameter for urethane slabjacking and can be over 2″ in diameter for traditional mudjacking applications.
Initial material injections will fill any under slab void space. Once the void space is filled, subsequent injections will start lifting the concrete within minutes. After the slabs are lifted, the access holes are patched and the work is complete. The process is rapid when compared to traditional remove and replace applications and is minimally disturbing to the surrounding areas.
Slabjacking technology limitations
- Poor quality concrete may crack and/or deteriorate when being lifted.
- Cracks can also develop in the concrete during the lifting process.
- Slabs built over filled-in land and/or poor sub-soils can also be susceptible to further settlement.
