Hydraulic Mudpumps

Our customers and business partners need an industry-leading partner who innovates on their behalf and supports them as they start and grow their concrete raising business. HMI began as RaiseRite Concrete Lifting, Inc. in 1974. At that time, the only slab raising pumps on the market were mechanical pumps designed in the 1950's, and needless to say, innovation wasn't a descriptive word for our industry. It was at that time that our founder, Ernest Cvetezar, designed and developed the first fully hydraulic slab raising pump.

Polyurethane concrete raising and mudjacking are two methods used to raise and support sunken or unstable concrete slabs, by drilling holes and pumping material under the concrete slab. Our polyurethane foam method uses the concrete slab itself as a means of delivering poly foams that raise concrete, fill voids, and stabilize soils. A hole is drilled through the slab into the subgrade. A tapered delivery port is installed into the hole. The injection gun is connected to the port. The injection gun delivers the polyurethane material through the port and slab.

Mudjacking is a cost-effective way to raise concrete, and is a sound alternative to concrete replacement. If you are in the concrete raising business, or are looking to enter into it, the HMIMini Mudjacking Trailer System is a budget-friendly, work-ready concrete raising equipment option. Our sales and service experts can help you determine if the Mini Mudjacking Trailer will fit with the market you are trying to service and fit into your budget!

Starting a concrete raising business is not only a concrete opportunity, it's a smart one, too! Concrete raising, as long as there's concrete to be raised (which there will be), will be in high demand for a long time. With ample opportunities in residential, commercial and municipalities, your opportunity for starting, gaining, and retaining business is greater and easier than most other new business investments. At HMI, we have over 40 years experience in providing concrete raising services, manufacturing mudjacking and polyurethane foam concrete raising equipment, and supporting our business partners.
