Mission Statement

To produce a quality Slabjacking pump; support our customers by educating, training, and supplying a superior product; maintain a leadership role in developing new and better slab raising systems; and to grow our company and create futures for both our customer and employees.

Philosophy

Hydraulic Mudpumps, Inc. believes that a well designed pump should be backed by an organization of employees who know how to raise concrete slabs. Since 1974, HMI has been very sensitive to input from our customers in the field and employee suggestions. Support of our customers is second only to the superior design of our equipment.

History

Raiserite Concrete Lifting, Inc. began in 1974. At that time, the only slab raising pumps on the market were mechanical pumps designed in the 1950's. Raiserite's founder, Ernest Cvetezar, designed and developed the first fully hydraulic slab raising pump. Hydraulic Mudpumps, Inc. was launched in 1979 to manufacture the HM-1 hydraulic mudpump.

The Power Pump series was launched in 1990. This pump is self-propelled, with a low hopper height, which makes it easy to load the hopper with mud. Other features include a remote control and the addition of a second pumping cylinder, which doubled the speed at which the material is pumped.

Customer demand prompted HMI to develop and manufacture a totally hydraulic mortar mixer the following year. This was another innovation for the industry because it eliminated the use of gears and belts to drive the paddles of the mixer, making them much more dependable.

As the mudjacking industry grew, it became apparent that slab raising pumps needed to be multi-functional. At the 2001 World of Concrete convention, Hydraulic Mudpumps introduced the VersaPump series of pumps. A new check ball chamber and pumping piston allows this pump to pump 3/8" down pea gravel concrete. The introduction of the VersaPump 1 and the VersaPump-2 included joystick steering and auxiliary hydraulics. The VersaPump can be driven and steered like a skid steer, and it can also be used as a power pack to run other hydraulic tools.

HMI is proud of all its innovations and products, but perhaps the greatest innovation is the Hopper/Mixer automated unit. The first fully automated unit rolled off the production line in March of 2003. This unit, when mounted on a truck body, can carry a slab raising pump, dry material, cement, and water. Along with its unique twin shafted mixer, it can mix and place mixed material into the hopper of a pump without human hands touching it.

Hydraulic Mudpumps, Inc. is committed to future refinements and developments to its product line. Our future will be determined by requests from you, our customer, and the upcoming industry demands.
