About Us

A concrete raising, industry-leading manufacturer & business partner.

A little bit about us: 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.

Say hello to HMI—your partner from start to success.

A beginning based on necessity

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. Consequently, Hydraulic Mudpumps, Inc. (HMI) was launched in 1979 to manufacture the HM-1 hydraulic mudpump.

Innovating for the future

Innovation and meeting customers’ expectations has driven us to become a world leading manufacturer of concrete raising equipment and material. With five decades of experience, we have led the concrete raising industry. We did this by developing and introducing self-propulsion, radio remote control, increased pumping speeds, and other improvements to our equipment to meet the concrete raising industry’s needs.

From mudpumps to automatic, volumetric mixer/hopper units to polyurethane foam, truck and trailer systems, we continuously research, innovate and produce the most effective and efficient products on the market.

The concrete raising products that we manufacture at HMI, along with our beginner / advanced concrete raising training, allows us to provide our customers with top-of-the-line products and the appropriate education to start and grow their concrete raising business.

How is HMI Polyurethane Foam Different?

Mixed Fresh for You!

HMI mixes polyurethane daily to order and has the advantage of selling you fresh material because it does not sit in a distribution center waiting for you to buy.

You never know how long other polyurethane foams were staged at the manufacturing facility before shipping and then sits at the distribution center.  Polyurethane foam has a shelf life and there are major benefits to buying manufacturer direct.

Simple, it’s because we care about Mother Earth

Actually, there are many reasons why HMI polyurethane foam material is different from the rest, but one of the main reasons is that HMI poly is made from over 40% recycled materials. That’s pretty impressive considering there is absolutely no other poly material on the market that offers this type of reduced carbon footprint!

Our polyurethane manufactured by our in-house chemist is an environmentally friendly, dual component polyurethane foam, specifically engineered for raising, leveling, and stabilizing concrete. Our patented materials (U.S. Provisional Patent Application No. 61/583.295) are made from recycled components, making it the “greenest” polyurethane foam on the market.

Being Green Requires World Leading Innovation

We care about our environment and manufacturing our products and materials in the U.S.A. At HMI, “green” is more than just a buzzword, it’s an active approach towards creating a more positive impact on the environment and our daily lives.

Environmentally-friendly Materials

Our foams are environmentally friendly, consisting of 39-49% renewable and recycled materials. Designed specifically for different applications, HMI provides top-of-the-line material, with the ability to ship anywhere in the world.

Local. Responsible. HMI.

For over 40 years, we have been a proud supporter of American-made products. Our mudjacking pumps, polyurethane  and mudjacking systems, and foams are all manufactured at our Manitowoc, Wisconsin facility in the United States of America.
