Oztec Industries began designing and manufacturing quality concrete vibrating equipment to meet the needs of the concrete construction industry. Immediately, the power, quality and reliability of Oztec concrete vibrators gained it a reputation as the best on the market. Oztec’s status in the industry remains! Continually improving existing designs and developing new ideas, Oztec provides the right equipment to produce superior concrete on any size job. Oztec’s line of fully interchangeable steel and rubber heads, electric and gasoline motors, back packs and portable mounts and flexible shafts are the most powerful, versatile and reliable in the industry.
Oztec Electric motors are manufactured to exacting specifications to withstand the rough day to day abuses associated with construction sites. Lightweight, compact and fitted with our comfortable adjustable shoulder strap, this one man power unit will speed through the stiffest concrete. Using the Vibrator Selection Chart allows you to combine power units with any of Oztec’s steel or rubber vibrator heads for maximum productivity.
All Oztec Power Units (gas and electric) run vibrator heads 11,000 to 12,000 vpm. They never drop below 10,000vpm even in the lowest slump concrete (near 0) when maximum head size specifications are followed.
Oztec power units come standard with the Quick Disconnect “QD” system. Changing shafts and heads on the job is a snap.
Tough, Rugged, and Durable! Oztec’s design has been extensively tested and used on-the-job for over thirty years. The wrap around protective frame and shock absorbers effectively protect Oztec motors from damage even when dropped or thrown from heights of over six feet.
Oztec units meet all United States OSHA and Canadian safety standards.
Common problems encountered with standard concrete vibrator heads for Tilt-Up Concrete Panels:
- Standard heads are not fully submerged and can overheat.
- Standard heads used horizontally churn air back into the concrete
Oztec’s Short RubberHeadTM … Ideal for Tilt-Up Construction
Oztec’s patented “RubberHeadTM for Tilt-Up Concrete Panels:
- Produces strong uniform shock waves the entire length of the head Short Heads remain fully submerged
- Prevents – overheating – Vertical position sends out horizontal shock wave
- Prevents – churning Urethane cover Prevents damage to finished surfaces
Combine Oztec Short Heads with an Oztec Gas Backpack or Oztec Electric Motor for perfect concrete consolidation on your next tilt-up project!
Oztec’s “High Efficiency RubberHeadTM” Outperforms any other type of vibrator.
Epoxy coated rebar presents a particularly troublesome problem. Steel heads act like an electric hammer, striking any rebar or forms they contact, over 10,000 times per minute, with a force from hundreds to over 2,000 pounds per blow. Contact with a steel vibrator head of as little as one second can chip enough coating to subject the steel to deep rust. Oztec’s patented High Efficiency “RubberHeadTM” vibrator head not only meets DOT non-metal head specifications for protecting coated rebar and expensive forms, but exhibit some very special and unique properties. The High Efficiency “RubberHeadTM” urethane dimpled construction sends strong shock waves off the entire length of the head, with a larger radius of action, producing denser concrete with less voids to patch.
Oztec’s patented “High Efficiency RubberHeadTM”:
- Will outperform any other type of concrete vibrator head…round, square, hi-cycle, etc…Any Type!
- Will protect epoxy coated rebar and expensive forms.
- Is outstanding in low slump (to “0” slump) concrete.
- Essential in large pours of very stiff concrete.
- Makes concrete denser with less voids to patch.
- Vibrates @ 12,000vpm, never drops below 10,500vpm when lowered deep into low slump concrete.
- Provides Superior Action.
- Is an absolute must for Architectural concrete where cosmetic surfaces are essential.
- All Oztec vibrators meet or exceed ACI (American Concrete Institute) specification # 309
Why the Oztec “RubberHeadTM” outperforms any other type of Vibrator.
(a.) When a smooth vibrator head (round, square or any other shape) is lowered into a relatively stiff concrete batch, the front or nose of the vibrator drills a hole. It pushes away concrete faster than it can return. Result, shock waves produced mostly from the vibrator’s front end.
(b.) Oztec’s patented “RubberHeadTM” has a large number of openings which allow wet concrete to cool the inner shell. These openings act like “suction cups”, which keeps concrete in contact with the entire length of the vibrator head, sending strong shock waves into the mass.
Oztec’s patented uniform, high efficiency action.

Who is Oztec Industries?
Formed in 1965, Oztec Industries began building it’s reputation as a designer and manufacturer of quality construction equipment with the introduction of their first Terrazzo Grinder. Quickly responding to industry needs for a powerful, rugged machine, the Diamond Terrazzo Grinder was developed and patented by Oztec. It “sped” through the grinding process four to five times faster than existing carborundum machines making seemingly impossible, costly projects, possible and profitable. For better maneuverability in small areas, Oztec developed the Single Blade Diamond Grinder, which is still popular today for grinding concrete. Gas and electric ceiling grinders were developed adjustable from seven to twelve feet. Clean-up of the job site was made easier with Oztec’s unique “terrazzo cleanup system” which constantly vacuums and pumps waste material outside the job site. Oztec grinders have produced top quality results on thousands of jobs over the years.
As a natural extension of their success in finishing terrazzo and concrete surfaces, Oztec Industries began designing and manufacturing quality vibrating equipment to meet the needs of the concrete construction industry. Immediately, the power, quality and reliability of Oztec vibrating equipment gained it a reputation as the best on the market. Oztec’s status in the industry remains! Continually improving existing designs and developing new ideas, Oztec provides the right equipment to produce superior concrete on any size job.
Oztec’s line of fully interchangeable steel and rubber heads, electric and gasoline motors, back packs and portable mounts and flexible shafts are the most powerful, versatile and reliable in the industry. With the development of the patented “RubberHeadTM”, Oztec has designed and produced a vibrator head that not only surpasses all the standards for protecting epoxy coated rebar, but is unequaled in consolidating concrete. The “RubberHeadTM” dimple design provides a more powerful radius of action along the entire length of the head, absorbs less vibration than steel and deflects, then pushes forward with high velocity.
The “RubberHeadTM” is an absolute must for Architectural and low slump concrete. Oztec Industries continues to explore and develop means of producing superior quality concrete…Oztec Industries…Advanced design…Quality Manufacturing…Superior Results…Oztec…Simply The Best!
What is concrete consolidation?
The American Concrete Institute defines it as:
Consolidation is the process of removing entrapped air from freshly placed
concrete. Several methods and techniques are available, the choice
depending mainly on the workability of the mixture, placing conditions,
and degree of air removal desired. Some form of vibration is usually
employed.
Freshly placed unconsolidated concrete contains excessive and detrimental entrapped air. If allowed to harden in this condition, the concrete will be porous and poorly bonded to the reinforcement. It will have low strength, high permeability, and poor resistance to deterioration. It may also have a poor
appearance. The mixture should be consolidated if it is to have the properties desired and expected of concrete. Consolidation is the process of inducing a closer arrangement of the solid particles in freshly mixed concrete or mortar during placement by the reduction of voids, usually by vibration, centrifugation (spinning), rodding, spading, tamping, or some combination of these actions.
