CONCRETE RAISING EQUIPMENT

Concrete raising equipment for polyurethane and mudjacking

When raising concrete, precision, and durability are crucial. Using inferior equipment can result in product waste and subpar performance. Failing to use high-quality equipment can result in the need to redo an entire job, costing you a significant amount of time and money. HMI designs 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.

A better alternative to concrete replacement

Concrete raising, often referred to as slabjacking or concrete leveling, is a fantastic alternative to repairing or replacing concrete slabs. There are two different methods for raising sunken concrete: mudjacking (sometimes referred to as slab jacking) or polyurethane foam concrete raising.

The process for raising concrete, whether by mudjacking or by polyurethane concrete raising, is very similar—differing mainly by material pumped. Simply put, holes are drilled into the concrete slab, mud material or polyurethane foam is pumped under the slab, and the voids under the concrete slab(s) are filled, thereby raising the slab. Finally, the drill holes are patched with a concrete mixture to complete the process.

Key Polyurethane Equipment

Our polyurethane 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.

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. Check out the links below to learn more about our mudjacking equipment:

OVER 40 YEARS OF EXPERIENCE

Here at HMI, we have over 40 years of experience manufacturing concrete raising equipment, materials and systems to raise and level concrete. Not only do we manufacture some of the industry’s best equipment and materials, but we also use them to provide concrete raising services through our sister company, RaiseRite; needless to say, we know what’s important for raising concrete the right way.

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.
