Polyurethane Floor Raising

When the components of this material are mixed a reaction causes the material to expand.

Polyurethane floor raising. Underneath the concrete a chemical reaction occurs where the two components mix to create an expanding foam. The methods are fairly similar with a few key differences. Both polyurethane concrete leveling and mudjacking are effective methods of concrete slab replacement. Raising an entire 2 car garage floor costs 1 100 to 2 200 for mudjacking or between 2 500 and 5 400 for foam injection.

Mudjacking a garage floor is cheaper than repouring new concrete or using a self leveling compound. You can then apply three coats of polyurethane to your floor allowing each coat to dry then sanding it and cleaning the floor in between coats. Raising concrete with polyurethane foam is an easy quick and inexpensive solution with benefits for residential commercial applications. Homeowners and business owners have found repairing concrete driveways walkways and patios has become less expensive and more effective with foamjection solutions.

The initial coat should be dry within a couple of hours and you can then apply a second coat. This expanded foam fills any voids and raises concrete. Mudjacking is effective for heavier concrete structures when used in conjunction with slab piers. In most cases mud jacking alone will not be able to lift both a slab and the heavy partition walls that sit on top of it.

The foam fills all voids and stabilizes loose and non compacted soil while expanding to create the lift. Both involve raising concrete in order to avoid removing and replacing your concrete. Strategically drill 5 8 holes in the concrete slab inject polyurethane concrete raising foam under the affected areas to lift the slab. A two part polyurethane mixture is mechanically injected through the hole utilizing carefully calibrated injection equipment.

Polyurethane concrete raising is a great way to repair settled concrete sidewalks patios driveways and garage floors. Work with the grain and avoid applying too much polyurethane to avoid raising the grain. Start by choosing a type of polyurethane oil or water based as well as a finish matte or glossy and make sure your work area is well ventilated. Apply a very thin coat of polyurethane with a fine brush foam pad or cloth.

The basic application technique for water based poly is similar to that for oil based. The average cost of mudjacking 2 to 4 sections of a garage floor is 300 to 900. Polyurethane concrete raising is a newer method used to achieve the same goal of fixing problems associated with settling concrete. During the process which is also known as foam lifting polyurethane foam is injected underneath a slab to fill and raise it.

This material will never lose density. It should not be considered as a standalone solution to lifting a footing or floor slab that has settled in your home.
