Concrete vibrators eliminate water and air bubbles by thoroughly shaking any recently poured concrete. After every pour, thousands of debilitating air bubbles are trapped inside the concrete, which may cause later weaknesses.
Without effective consolidation from concrete vibrators, expect voids, honeycombing, poor rebar bonding and rock pockets from the concrete. This may affect the structural integrity of your foundation.
These tools are well suited for small tasks, such as filling insulated concrete forms and setting streetlight footers.
To provide expert consolidation of concrete, the best concrete vibrator ought to be extra powerful, compact size and with a good frequency.
Your search for the best concrete vibrator may seem difficult as there are many models out there. However, worry not as our concrete vibrator review below will help you ease the search process.

What to Consider Before Buying a Concrete Vibrator
With the plenty of concrete vibrators present in the market, how do you get to know the best?
Well, there are several factors to look into before settling on one. The best should provide just enough vibrations to eliminate air bubbles and water presence.
Note that excessive vibrations can cause bulged walls or blowouts. Therefore, finding the perfect and most suitable vibrator for your intended tasks is of immense importance.
Outlined below are some of the factors to consider when searching for the best concrete vibrator on the market currently.
The Type of Concrete Vibrator
There are several types of concrete vibrators out on the market. They include:
Perhaps the most common concrete vibrator in use currently, immersion vibrators have a steel closed and rounded tip that encloses the vibrating element. The vibrator’s tip is connected by a flexible hose to an electric motor.
For best results, the diameter of the flexible hose ought to be small enough to fit between the reinforcing bars. For effective consolidation, it is recommended that it is inserted at intervals of 24 inches or alternatively, 8 times the tube diameter.
Insertion time when in use should vary between 30 seconds to 2 minutes as concrete is poured in layers at least thicker than 24 inches high. For beginners, the vibrator should be vertically inserted into the mix and slowly withdrawn.
Immersion vibrators work by allowing air bubbles to float up as they exit the concrete. To facilitate this, the tip should be withdrawn slowly to facilitate upward air movement, perhaps about 3-inches per second.
For cases where the wall is poured in multiple lifts, ensure that the immersion tip inserts deep enough, extending up to 3 to 6 inches of the previous layer. Buyers can always choose the radius of the tip depending on the intended use.
Unlike immersion vibrators, external vibrators are attached to the concrete’s formwork at certain points. Determining the location of these points involves considering the thickness of the concrete and the concrete’s mass.
When attached, external vibrators exert direct vibration effect on the formwork and concrete. This is probably the reason why they consume more power compared to other vibrators.
Besides, they consolidate concrete to a radius of 18 inches away from the attached formwork.
External concrete vibrators are preferred in activities where heavy or column concentration of rebar may result in tangling of the internal head.
Such activities include casting yards and precasting facilities where other vibrators such as immersion vibrators cannot be used.
As the name suggests, surface vibrators are placed at the top of concrete being poured. They work well in shallow structures and slabs as well as concrete with a low water to cement ratio.
They produce relatively low vibration rates. Thus, they are not suitable for heavy or thick concrete layers.
Rebar shakers are a good alternative to traditional vibration techniques. The working technology of rebar shakers is similar to regular vibrators, but are slipped over the top of reinforcing bars.
They shake, producing vibrations that are transmitted to the concrete.
Rebar shakers are available in various diameters, which often save a lot of working hours as well as reduces clean-up activities.
Overall, they shorten the time taken to pour concrete into a cell or a tight space.
Number of Vibrations and Strength
Besides the type, this is the other crucial factor to consider before settling on one concrete vibrator. Vibrator models are different with different vibration speed, often marked as Vibrations Per Minute.
This indirectly determines the effectiveness of the machine as well as the time taken to complete the task.
Whereas some vibrators are designed to shake a certain area, others have the power to shake almost the entire piece. Always make a choice based on your intended application.
Other essential factors to consider before buying the concrete vibrator include;
- The number of reviews – it is imperative if you consider advice concerning the best and worst concrete vibrators on the market to avoid. This will aid you to narrow your choices.
- Quality – going for a premium quality concrete vibrator can be quite expensive but worthy. Such machines are reliable and durable.
- The cost – there are various concrete vibrators coming in a wide range of prices. Go for one that suits your budget. Note that not all expensive vibrators are the best.
- Concrete vibrator’s weight – always find a lightweight and easy to handle concrete vibrator.
