The AirTight® Raising Process:
The AirTight Process is similar to mudjacking, but is an evolved application that allows us to provide our clients with a clean, quick, long-lasting solution. Our process effectively stabilizes soils, fills voids and lifts concrete using high-density polyurethane foam. The following are the steps for The AirTight Process.

The AirTight Advantage Smaller Holes | Lightweight | Fewer Holes | Long Term

A site evaluation will be performed by AirTight to gather all necessary information to complete the project. This includes inspecting the foundation, footings and concrete for settling and determining what environmental factors will be present. Once the scope of work has been determined we gather any documents that can assist us with the project (soils tests, engineering reports, building blueprints, etc.). This allows us to confidently apply the right geo-polymer for the repair.

Depending on the factors of the project, and before any polyurethane injections take place, the concrete floor or slab may need to be scanned using ground penetrating radar technology to locate utility and plumbing lines, rebar, in-floor heating, etc.

Once the area has been scanned and marked, AirTight technicians can safely and confidently drill a series of access points in the affected area. These access points are small, 5/8" drill holes that allows the polyurethane foam to be injected under the concrete.

Specially designed ports are securely attached to the access points. Enclosed inside a mobile unit is one of our pressurized systems designed for the injection of polyurethane grouts. Attached to the unit is a heated hose that securely attaches to the small access ports.

The polyurethane foam is injected through the ports crawling deep into loose soil base. The expanding foam stabilizes loose soils and fills all subsurface voids. Crews carefully monitor the process to insure a safe and effective lift.

Once the sunken concrete has been leveled and stabilized the access points are patched and area is ready for use.

The AirTight Advantage

Smaller Holes
With polyurethane foam, we are able to use smaller drill holes than what is required with traditional slabjacking methods. AirTight uses small, 5/8" (dime-size) drill holes to complete our concrete raising projects.

Polyurethane foam is a light weight material compared to traditional mudjacking slurry (2-6 pounds of polyurethane foam vs. 100-130 pounds of mud slurry). Because of the light weight properties of our foam, it won't burden the underlying soils which are often loose and poorly compacted. Mud slurry is extremely heavy and within a couple years can compact the loose soil base causing resettlement.

Fewer Holes
With foam, fewer holes are drilled in your concrete for a cleaner look compared to mudjacking. Because polyurethane foam enters the soil base as a highly pressurized liquid, we can achieve a large coverage area from each injection site. Our polymers can flow and expand anywhere from 4 to 15 feet from each injection site. Because of the heavy nature of mud slurry only 1-2 feet of coverage should be expected from each drill hole. As a result 50%-75% more holes are needed to repair sunken concrete with mudjacking.

Long Term
Lifting settled concrete with polyurethane foam is considered a long-term repair, not a temporary fix. Our lightweight high-density foams won't loose density like mudjacking slurry. Our hydrophobic foams cure in 25 - 45 minutes and will completely maintain their compressive strength. Also, our foams won't break down or washout from water, making The AirTight Process a long-term solution.
