Frequently Asked Questions About Concrete Leveling in Tempe, AZ

A good fit comes down to evaluation quality, insurance, relevant experience, a clear explanation of methods, repair-vs-replace judgment, and a clear estimate — not unsupported ratings. Ask whether the contractor inspects the slab before recommending lifting, whether they are insured, and whether they will tell you when replacement makes more sense than leveling. The right contractor gives you an honest read on your specific slab.

Tempe Concrete Leveling works with 10+ years of hands-on concrete leveling experience. That experience covers inspecting settled slabs, measuring elevation differences, and making lifting and stabilization decisions across driveways, sidewalks, patios, pool decks, garage floors, and commercial flatwork. We do not publish a specific founding year because we have not verified one.

Yes, Tempe Concrete Leveling is insured for residential and commercial slab work. We do not state specific policy limits or carrier details; we confirm the insured status that matters to property owners.

Yes, a contractor should always inspect the slab before recommending lifting. An on-site inspection reveals the crack pattern, deterioration, elevation difference, drainage, and surrounding conditions that determine whether the slab can hold its lifted elevation. Recommending a lift without looking risks selling a fix that will not last on an unsuitable slab.

Concrete leveling is the process of raising a settled, uneven slab back toward its intended elevation by lifting it from beneath rather than tearing it out and replacing it. A contractor evaluates the slab, then uses a controlled method — such as polyurethane lifting or mudjacking — to lift and stabilize suitable concrete. It is appropriate only when the slab is structurally sound enough to hold the lift.

Polyurethane foam concrete lifting is a method that uses small drilled injection points and an expanding polyurethane material to raise a settled slab. The foam is pumped beneath the concrete and lifts it as it expands, offering controlled lifting with relatively small holes. The method is chosen based on the slab condition, void, and access — not as a universal fix.

Polyjacking is another name for polyurethane foam concrete lifting. It refers to the same process of injecting an expanding polyurethane material through small drilled ports to lift a settled slab. The terms polyjacking and polyurethane lifting describe the same method and are often used interchangeably in the trade.

Mudjacking, or slabjacking, is a traditional lifting method that pumps a cementitious slurry beneath a settled slab to raise it. It typically uses larger injection holes than polyurethane lifting and a heavier fill material. Contractors may consider it where a heavier slurry suits the slab, void, and load conditions and access allows for the larger holes.

Neither method is automatically better for every project. The right choice depends on the slab condition, void size, site access, expected load, surrounding conditions, and repair goals. Polyjacking generally leaves smaller holes; mudjacking uses a heavier fill material. A contractor selects based on the specific slab, not a default preference for one method.

Concrete should be replaced instead of leveled when it shows severe deterioration, fragmentation, unsuitable structural condition, or problems outside the scope of slab leveling. A slab that cannot predictably hold its lifted elevation, or that is extensively cracked through its structure, is a poor candidate for lifting and may be better replaced or evaluated by a specialist.

Concrete in Tempe can settle when support beneath the slab changes because of conditions such as poor compaction, voids, erosion, washout, drainage problems, or changing soil moisture. Long dry periods and seasonal monsoon moisture can contribute. We do not claim every case shares the same cause; an inspection identifies the likely factors for your slab.

Yes, accessible voids beneath suitable slabs can be filled to improve support. We locate the unsupported area, fill the accessible void with an appropriate material through injection, and improve support beneath the slab. This does not imply deep-soil stabilization or foundation repair, which are outside the scope of void filling.

Some cracked slabs can still be leveled, but the crack pattern, deterioration, and structural condition determine whether lifting is appropriate. A few isolated cracks in otherwise sound concrete may not prevent lifting, while widespread or structural cracking can mean the slab will not hold. We assess the cracks before recommending any repair.

No, concrete leveling is not a foundation repair method. Leveling addresses settled surface slabs such as driveways, sidewalks, and patios. Suspected structural or foundation movement may require appropriate specialist evaluation. We are clear about the boundary between slab leveling and foundation work so you are not misled about what lifting can do.
