Concrete vibration is an essential step when it comes to concrete construction projects. This is because when pouring out the concrete, it may probably have some air bubbles that might, in one way or another, weaken your concrete structure.
Thus, the concrete vibrator is meant to produce robust concrete via vigorously shaking your concrete right after pouring to eventually get rid of air bubbles. However, appropriate use of the concrete vibrator tends to work magically when it comes to minimizing surface blemishes and defects. San Rafael concrete vibration got you covered.
What exactly is this vibrating concrete?
This is a machine or a tool that vibrates concrete to eventually expel air traps and water in it. Besides, the concrete vibration San Rafael helps in minimizing internal friction via randomizing concrete mixture. Overall, the vibration tends to aggregate concrete particles and rearrange the cement to achieve expected and close configuration.
So how does concrete vibrator works?
Generally, there are various types of the concrete vibrator, and they all work in different ways. Without further ado, let dive into different categories on how concrete vibrators tends to work.
Formwork or form vibrators
This type of vibrator is meant to work with the precast concrete. This means the user should attach the form vibrators into outside of his concrete form to make them vibrate air bubbles out. Below are top tips to use formwork vibrators:

– Use the multiple vibrators
In the extensive pours, consider attaching several vibrators. And that way, you will have complete agitation of your concrete as well as dissolve the air bubbles. Further, remember to space vibrators to about 6 inches apart for excellent results.
– Submerge vibrator completely
Make sure your vibrator heads will go direct to concrete formwork. Also, be attentive not to eventually turn your vibrator on when parts of heads remain right above the concrete surface.
– Ensure formwork vibrates freely
This formwork requires vibrating sufficiently. Thus, molding or mounting the formwork to spring-loaded isolation aids to ensure you have unimpeded concrete vibration.
– Utilize vigorous vibration when needed
The low-slump concrete is less workable and stiffer compared to others. So, they require harder vibration to get rid of all remaining air bubbles.
– Internal or immersion vibrators
This are known as internal vibrators are they are common concrete vibrators that professional work with. Besides, for people using this type of vibrator consider pushing it to wet concrete followed by slowly withdrawing it. Below are tips for using immersion vibrator:
– Prevent the cold joints
Such joints tend to develop when there is insufficient bonding happening right between an old and new layer of your concrete. And to prevent this problem, you should place vibrator tip for about 6 feet to previous concrete layer.
– Vibrate using regular pattern
For some individual who might prefer to use an internal vibrator, ensure you place it right at regular intervals in the concrete. This is because the random insertions may result to air bubble dissolution or uneven compaction.
– Keep your vibrator vertical.
Hold your concrete vibrator in the proper position when working. Besides, this orientation allows it to work effectively. But be attentive not to bend your vibrator since it might sustain ever-lasting damage.
Surface vibrators
Jumpers or surface vibratos are meant to directly go to the top of users’ poured concrete, and they are Appropriate for the concrete slabs, which are 6 feet less or deeper. Below are helpful tips of using surface vibrators:
– Complement with immersion vibrator
In essence, if you are dealing with a bit deep or surface with lower layers consider to complement surface vibrator with immersion for comprehensive compaction.
– Opt for right vibrator
Do this because the surface vibrating tools tend to come in different types, such as single or double bean screeds, vibrating roller screeds, and pan-type vibrators. However, the latter is most used when paving.
Well, based on the experts, concrete vibrating procedure may take in between five and 15 seconds. And if the bubbles are still appearing in your concrete once you remove your vibrator, consider repeating this process ensuring no bubbles to have excellent final results.
Why is it necessary to vibrate concrete?
Generally, our concrete is always recommended to make them smooth and stronger. However, based on the project, someone might have no other choice but to dive into vibrating concrete, most probably if is major building code requirement.
What you should know to use a concrete vibrator?
First, verify the particular zone where concrete is not vibrated. Submerge your vibrator head fully in the concrete; hold It for about 10 seconds. Once it is fully submerged, pull your vibrator right on about 3 feet average rate per second. Further, overlap previous radius of your vibration anytime you fully insert the vibrator. Stop vibrating the concrete when no air bubbles appear or escape from your concrete work.
