Precision and durability are crucial when raising concrete. Using inferior equipment can result in product waste and subpar performance, ultimately costing you valuable time and money. At HMI, we understand that investing in high-quality concrete lifting equipment is essential for achieving successful results on every job.
We design polyurethane and mudjacking equipment that gets the job done right the first time. We’ve worked hard to perfect our engineering process, creating innovative and effective concrete-raising equipment. Our mudjacking and polyurethane equipment are easy to use, delivering precise results every time.
HMI’s solutions enable you to complete concrete leveling projects efficiently and effectively. Our EliteONE injection gun and renewable-based poly foam set us apart from the competition. Our commitment to quality means our equipment withstands rigorous use while providing reliable performance over the long haul.
Concrete raising, often called slabjacking or concrete leveling, is an excellent alternative to repairing or replacing concrete slabs.
Besides saving time and money, concrete raising minimizes environmental impact by reducing waste associated with full slab replacements.
There are two different methods for raising sunken concrete – mudjacking, sometimes referred to as slab jacking, or polyurethane foam concrete raising. Both processes involve drilling holes into the concrete slab, using a concrete lifting pump to pump either mud material or polyurethane foam beneath the slab to fill voids, and subsequently raising it back to its original level. To conclude the process, the drill holes are patched with a concrete mixture for a seamless finish.

Our advanced concrete slab lifting equipment incrementally raises concrete, filling voids and stabilizing soils in the process. We also pioneered a van system, allowing you to conveniently run a concrete raising business without investing in a truck or trailer. Explore our high-quality polyurethane equipment options:
No matter what type of job you’re doing, you need reliable equipment that minimizes the risk of accidents while delivering precise results that satisfy customers. Mudjacking equipment from HMI ensures uniform concrete raising, ensuring long-lasting results. Learn more about our mudjacking equipment:
These tools are essential for effective concrete leveling, ensuring minimal disruption during the lifting process while providing long-lasting results. Our polyurethane foam comes in lightweight and high-density options with different cure speeds, allowing you to choose the best solution for your needs.
These durable solutions provide everything you need for successful concrete slab lifting while boosting safety and efficiency on every project. Our hydraulic pumps provide maximum power output while minimizing operator fatigue, making them ideal for small or large jobs.
At HMI, we have over 50 years of experience manufacturing concrete raising equipment, materials and systems to raise and level concrete. We manufacture some of the industry’s best equipment and materials and use them to provide concrete raising services through our sister company, RaiseRite.
We still own and operate the original RaiseRite business — built for contractors by contractors with decades of experience.
Our extensive knowledge ensures we understand what it takes to raise concrete effectively while maintaining high standards of quality and service. We prioritize continuous improvement by regularly updating our product offerings based on industry advancements. Our team of experts is committed to providing innovative solutions that meet the evolving needs of concrete professionals.
There are many things that can cause concrete to settle, all of which do not always require concrete replacement to fix.
Poor or improper compaction of the base before concrete was poured: The weight of the slab will further compact the base after curing, and settlement can happen quickly.
Climate: The Polar Vortex experienced last year by many in the northern hemisphere wreaks havoc on concrete slabs. Freezing and thawing causes slabs to expand when frost is in the ground. Frost causes concrete to heave or raise. When the ground thaws, the concrete will settle again, but many times not to where it was originally. This results in trip spots between shifting slabs. On the opposite end of the climate spectrum, heat and drought can cause expansive clay soils to shrink, causing concrete slabs to settle. When those clay soils receive much needed rain and expand, the concrete slabs become unlevel.
Erosion: Damaged water or sewer lines, improperly placed downspouts, excessive rain can all lead to washout of base materials under concrete causing slabs to settle.
Machine/Traffic Vibrations: Concrete slabs may move or settle in industrial or highway settings where there is frequent movement and heavy loads being transported. The vibrations from machinery and passing traffic can lead to the base compacting and slabs settling or moving. Case study
Slab Curl/Rocking Slabs: Slab curl occurs when a relatively large section of concrete is poured. During the curing process, the top slab may cure slightly faster causing the slab to curl, rock, and become unstable. Vibration can also cause slabs to settle.
There has always been a high demand for concrete leveling and raising. Settled concrete needs to be addressed, not only from an aesthetic standpoint, but, more importantly, from a liability standpoint.
The American Disabilities Act of 1990, defines a “trip hazard” as any vertical change over ¼” or more at any joint or crack. This law strictly mandates the repair of trip hazards from sunken or heaved concrete in public areas, as it represents a legal liability. Municipalities, school districts, hospitals, private communities, shopping malls, universities, apartment complexes, and any other property owners are continuously concerned regarding any possible liability issues.
