Polyurethane foam foundation repair is a faster, non-invasive alternative to interior pilings. URETEK pioneered and perfected the polyurethane injection process in Our injection process is called The URETEK Method® and it’s used to lift and stabilize interior foundations. The polyurethane foam we use is patented and unlike any other. Light weight: The polyurethane foam weighs only 4lbs. per cubic yard, opposed to lbs. of typical concrete or mud. Greater lifting power: Although light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking Precise lifts: Metered, intermittent injections ensure more precise control of the lift.
Slab Lifting by injecting structural polyurethane foam into voids beneath settling or uneven concrete slabs is a proven method to stabilize without excavation and without adding much weight. This process of slab jacking is alo known as foam jacking, polyurethane concrete raising, poly jacking, poly leveling. is a polyurethane foam. Mudjacking: a repair technique for lifting concrete slabs that have settled over time with a mortar-based mix. Mudjacking involves pumping a mortar-based mixture of “mud” or “slurry” underneath a settling slab. This injected material is a mixture of water, soil, sand .
POLYURETHANE FOAM STABILIZES CURLED FLOOR SLABS. John Kelley of Advantage Construction in Quincy, Mass. was facing a dilemma; curling concrete floor slabs were slowing down his client's busy , square-foot warehouse. The phenomenon is typically referred to as "slab curling" – the distortion of a slab into a curled shape by distortion at the edges. Two-component resin injection gun manufactured specifically for lifting concrete slabs, designed to handle back-pressure. As the essential piece of foam jacking equipment for Alchemy-Spetec’s expanding polyurethane foams, the resin injection gun provides highly-efficient concrete leveling.

Mudjacking and polyurethane injection work to fill the voids in the soil under the structure, and help halt the unfolding catastrophe. Mudjacking lifts the concrete foundation up on a densely-packed, swelling wave of slurry (a mixture of hard fill including mud, sand, cement, crushed limestone, etc.), while polyurethane injection utilizes dense.

SE, Suite B Salem, OR and Federal Highway Administration Seventh. Polyurethane Foam Jacking, Injection, Void Fill At A-1 Remodeling & Building, we can raise concrete slabs and level them by means of polyurethane foam injection or Polyurethane slab jacking.
We can also fill voids under concrete slabs, behind bulkheads, under foundations and in. Question #3: A feature of polyurethane that will make the end results more attractive especially to the residential market is a smaller injection hole.
Polyurethane utilizes a hole that is only 5/8” or smaller compared to mudjacking holes that run between 1” and 2”.
Mudjacking is more effective at completely filling subsurface voids. When polyurethane foam is injected, it will expand to fill a specific area.
Then, it will stop, and it will harden. This limits the ability of polyurethane to completely support the concrete above, making mudjacking a more effective solution in. While polyurethane foam jacking is suitable for most concrete raising or stabilizing projects, there are some situations that are better for foam injection than others.
Heavy slabs: Polyurethane foam has the ability to spread under large areas before expanding and a high expansion force, which allows it to easily lift heavier slabs.
There has been quite a bit of "buzz" about polyurethane form otherwise known as Poly lifting/jacking/leveling as a substitute for cementitious grout generally pumped with original traditional mudjacking. Before you jump on that bandwagon, we Injected polyurethane slab jacking book like to share some vital information about polyurethane foam that should change your mind.
Equipment – Mudjacking- grout mixer, water source, grout pump, hoses. Polyurethane injection- Reactor, heated hoses, injection gun.
While both methods will raise concrete Polymer injection is less invasive, using much smaller and fewer holes, provides more uniform support under the slab, is a quicker process and allows for immediate use after.
The process starts with ⅝” injection holes (size of a dime) strategically drilled to lift and restore sunken concrete. Polyurethane foam is injected into the holes causing a chemical reaction to fill uneven space under the slab.

Stein has also worked in public relations. These voids need to be filled to raise the sunken slabs back to level and provide ongoing support. It’s at this point that homeowners are faced with the choice of which method to use to fix the issue: Mudjacking or PolyLevel polyurethane foam injection.
Concrete Lifting With Mudjacking. At first glance, mudjacking seems like a common-sense. Polyurethane foam is the other option for lifting sunken concrete and filling voids.
This system is ideal for use in situations such as inside finished buildings or confined areas. Osco Mudjacking & Shotcreting Ltd offers polyurethane foam for residential, commercial, and industrial applications.
Among the leading high density polyurethane foam products available, AP Lift offers a powerful solution that is traffic ready in 15 minutes. This two-component, high-strength, high-density, hydro-insensitive structural polyurethane foam suppo lbs per square foot.
Mudjacking requires much larger holes, typically 1 - 2 inches in diameter. Large holes can weaken the structure and the patches are more noticeable.
Injection Hole Quantity: Polyurethane is injected as a thin liquid and travels easily between the slab and subsurface, therefore requiring fewer holes to obtain the required coverage.
Mudjacking uses a sand based material that is infused with portland cement. This slurry is hydraulically pumped under the slab to fill voids and raise the concrete.
Mudjacking material weighs on average lbs per cubic foot. Polyurethane Concrete Raising uses a foam material that is injected under the slab. When the components of this. Although concrete raising results between polyurethane foam injections and old “mudjacking” methods may appear similar, there are significant differences between polyurethane and mudjacking methods.
From the repair process to the materials and equipment used, foam jacking proves to be a far superior and sustainable repair method in the long.
The average cost of a residential mudjacking project is anywhere from $ to $, although it can be more or less depending on the condition of the foundation or surface.
Mudjacking Pros. Less expensive - Mudjacking is significantly less expensive than polyurethane concrete raising, so it’s a good choice if you’re on a tight budget. Mudjacking Advantages and Disadvantages. Traditional mudjacking can reach higher strengths, costs less than the polyurethane materials, much more practical for large void filling (+6”), nontoxic, nonflammable, and easier to acquire materials.
It does have a heavier burden on the soil at +lbs per cubic also breaks down over time due to erosion, or by digging animals.
Polyurethane Concrete Raising vs Mudjacking. May 2, • By Matthew Stock. When you have to repair settled concrete around your home that is unsightly, a tripping hazard, pooling water or directing water into your basement, there are a couple of methods to choose from besides replacing the concrete.
Both Polyurethane Concrete Raising and Mudjacking are processes in which existing. Mudjacking usually involves heavy work (shoveling material into a mixer), drilling /8” holes and moving a pump around the job site.
Polyurethane concrete lifting is usually pretty light work. The poly rig can be brought close to the area being raised and a light weight hose is then used to reach the 5/8” injection holes. High-density polyurethane foam is injected into ⅝” holes that expand to lift and level the sunken concrete.
Polyfoam is stronger and longer-lasting than traditional mudjacking. Concrete leveling foam cures in 30 minutes, is mold and water-resistant, is not subject to erosion, and provides 6, to 14, lbs. per square foot of support.Foam injection offers a better, longer lasting alternative to mudjacking or expensive replacement.
Polyurethane concrete lifting uses a high-density foam material that is injected under the slab. When the components of this material are mixed, a reaction causes the material to expand.Polyurethane concrete raising achieves the same results as traditional mudjacking, but with a lightweight material that requires smaller and fewer injection holes.
Also known as foam lifting, polyurethane concrete raising is the latest and greatest concrete repair method available.
