Voeller, the manufacturer of the original Mud-Jack, brings you an exiting new design.  It’s the all-hydraulic H-200 Mud-Jack a completely self-contained system that saves time and restores your sunken concrete slab to its original grade faster and with less disruption than ever before.

This H-200 Mud-Jack system eliminates the hazard and potential liability problems of sunken slabs quickly.  You don’t have the high cost, delays or the inconvenience encountered with the reconstruction process.

The H-200’s compact size enables you to set-up, charge, mix and pump material with greater ease and speed than has been possible.  The end result is firm, solid base that extends the useable life of concrete construction without any appreciable down-time and at a reasonable cost.  The system can be used to raise concrete slabs on streets, bridge approaches, curbs, gutters, driveways, sidewalks, pool decks, patios, garage and basement floors…anywhere slab has slipped due to the settling of base materials.

Exceptional Hydraulic Efficiency

The H-200 is an all-hydraulic machine. There are no mechanical drive parts to service and maintain or create problems that slow projects.  The hydraulic system has been provided with a remote variable speed control.  A convenient, hand held, electric, dead man control switch on a 30 foot cable permits you to vary the speed of the pumping piston (0 to 13 strokes per minute)- high speed to fill voids and low speed for final lifting.  The maximum output is approximately 225 cu. Ft. per hour.

Compact, Clean Design

The Voeller H-200 has been designed to make servicing easy.  There is ample working space for making engine checks, inspection of the hydraulic system functions.  You’ll like the open design and how easy it is to keep the machine clean.

High Performance Mud Pump and Cylinder

A high-performance variable speed mud pump is used in the H-200.  It has a single piston with rubber piston ring and shims, inlet valve and 500 cubic inch nickel-lined mud chamber.

Thorough Mixing Makes Mud-Jacking Easier

The H-200 has a paddle-type mixer that provides continuous flow through mixing.  Its 54” long, 16” wide, 24” deep material hopper keeps the charging routine easy and simple.  Mixing shaft has sealed anti-friction bearings, independent packing glands and replaceable mixing blades.
