Our industry-leading services include:

Stone Slurry Grout Leveling

The traditional Grout Leveling process has been in existence since the early 1900’s. Grover Miller, our founder, developed our patented self-contained pumping unit in the early 1980’s and made grout leveling affordable and accessible to the public. A-1’s Stone Slurry Grout Leveling can reach strengths as high as 5,000 psi, is much more practical for large void filling, and is nontoxic and nonflammable. The A-1 system represents a tremendous cost savings in terms of labor, materials, and time over other concrete leveling methods. Our patented equipment allows for very precise adjustments when lifting the slab, creating an optimal solution for you.

With Stone Slurry Grout Leveling, A-1 drills a series of one-inch diameter holes (about the size of a quarter) through the slab and hydraulically pumps an environmentally friendly, limestone-based slurry beneath the concrete. When the void is completely filled, the slab is slowly repositioned to its optimum point of recovery. Because the amount of material and speed of the lift is controlled, less stress is put on the affected area, substantially reducing the risk of stress cracks. Stone grout reestablishes a rock-solid sub-surface—effectively creating a new, stable base. This helps prevent settling in areas where freeze/thaw conditions predominate. The holes are then patched with non-shrinking grout, and the concrete can be used immediately after the job is done.

This method is many times confused with slab jacking and mud jacking, both of which often use inferior slurry materials and larger holes.

Injection Foam Leveling

Polyurethane foam, used for years as an effective insulating product, is now being used for concrete leveling. It utilizes smaller injection holes, offers a cure time of just 20 minutes, and holds its shape for many years. The foam is dense and solid, providing a strong support to the slab above it. A-1’s foam leveling uses an American made, commercial grade polyurethane material. As with Stone Slurry Grout Leveling, A-1 drills a series of holes (smaller than the size of a dime) through the slab and injects a two-part polyurethane material under the concrete. Through chemical reaction the material expands, filling voids and raising the concrete. In only seconds, the foam will reach its final volume. After curing, it will never lose its density and will maintain its compressive strength. Our foam leveling material won’t break down or wash out from water.

A-1 also offers GREENGUARD Gold certified foam which offers stricter certification criteria, considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and healthcare facilities.

Foam Leveling, Polyjacking, foam-jacking, poly-lifting, and poly-leveling are all terms describing more recent methods using polyurethane foam to achieve similar results to traditional grout leveling.

Concrete Grinding

An inexpensive repair technique that mechanically grinds away elevated and protruding edges, primarily on concrete sidewalks where slab sections have settled or heaved. While less expensive, this repair is often only temporary, as slab sections may continue to move. The structural integrity of the slab may be compromised by reducing its thickness, which can lead to cracked or broken concrete in need of complete replacement. This method also produces a large, obvious repair area with an exposed aggregate appearance. Another drawback is that once an area is “ground”, the option of grout of foam leveling of adjoining slabs may become impossible. Nevertheless, despite its drawbacks, this method is occasionally a necessary part of the leveling process to achieve the best result.
