What Causes Concrete to Sink or Settle?
Concrete slabs and driveways can be susceptible to settlement from an extremly wide variety of factors. In many areas of the United States, naturally occurring soils can consolidate over time, especially in the areas of the mid-west United States specifically areas ranging from Texas up through to Wisconsin. Soil erosion wash out also contributes to concrete sinkholes and settlement, as this is very common for locations with poor or improper drainage. Concrete driveways or slabs built upon filled-in land can over excessively settle as well. This is common for many homes with basement levels, as the fill material or dirt on the outside of the foundation frequently is not "compacted" properly or at all. In some cases, the concrete slabs pitch down, directing water down towards the basement level. Tree roots can actually heave a slab upwards; this is quite common along public roadways, especially within Metropolitan areas.
What is Mudjacking?
Mudjacking is a specialty concrete repair technology. In essence, mud jacking attempts to lift a sunken concrete driveway by pumping a grout mixture through the concrete underside, effectively pushing it up from below. The process is also commonly referred to as "slabjacking" and "pressure grouting" as well. Accounts of raising large concrete slabs through the use of hydraulic pressure date back to the early 1900's. Early contractors utilized 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 utilize 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 slab, driveway or sidewalk that is strategically located to maximize lift. These holes are generally 5/8" diameter for urethane slabjacking and can be over 1" in diameter for traditional mudjacking applications. Initial material injections will fill any underslab 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 very rapid when compared to traditional "rip and replace" applications and is minimally disturbing to the surrounding areas.
When did mudjacking originate?
In civil engineering, concrete leveling (mudjacking) is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a less expensive alternative to having the damaged concrete torn-out and replacement concrete poured, and is commonly performed all around the world. In 1977, the term concrete leveling was coined by Randall Greene in Cleveland, Ohio.He created the phrase to convey his company's ability to both raise and lower concrete to correct the insufficient grade of a slab.
What is Concrete Leveling with Foam Injection?
Foam leveling utilizes two part closed cell polymer expanding foam injected through a hole less than one inch in diameter, typically 5/8". Although the material is injected at a higher psi rate than traditional cementious grouts, the pressure is not what causes the lifting. The expansion of the injected material below the slab surface performs the actual lifting action. Material injected below a slab to be lifted will first find weak soils, expanding into them in such a manner as to consolidate and cause sub-soils to become more dense and fill any voids below the slab. One inherent property of expanding foams is that they will follow the path of least resistance, expanding in all directions. Another inherent property includes reaching a hydro-insensitive or hydrophobic state when cured with 100% cure times as little as 30 minutes. Closed cell polymer foams offer benefits which go beyond the goal of leveling hard surfaces. They will not retain moisture, which in northern climates can cause frost heaving. They are not subject to erosion once in place. Their fast cure time allows for immediate use when application is complete. Their light weight, 3 to 8 lbs. per cubic ft. vs. 100 to 120 lbs. per cubic ft. for cementious grout will not cause further settlement. Foams will retain their cured shape and volume indefinitely reducing the possibility of new voids forming below grade to nearly zero unless acted upon by some outside cause. Some closed cell polymer foams have baseline lifting capabilities of 6,000 lbs per sq. ft. and leveling procedures have been performed in which loads as high as 125 tons have been lifted and stabilized in a surface area of less than 900 sq. ft.
