Description
The Dera Electric Vibrator Small is a portable concrete vibrator made for compacting fresh concrete in columns, beams, slabs, foundations, lintels, staircases, and small construction projects. It helps remove trapped air bubbles from wet concrete so the structure becomes stronger, smoother, and more durable.
This small Dera concrete vibrator is a good choice for fundis, contractors, builders, masons, hardware shops, and site workers who need a light machine that is easy to move around the site. Unlike the big petrol poker vibrator, this small model is electric and handheld, making it easier to use in homes, small buildings, repair jobs, and indoor concrete work.
Why Use a Small Dera Electric Concrete Vibrator?
When concrete is poured, air pockets can remain inside the mixture. If the air is not removed, the concrete may become weak, rough, and full of holes. A concrete vibrator shakes the wet concrete at high speed so the mix settles well around steel bars, corners, and formwork.
The small Dera electric vibrator is useful because it is easy to operate, lighter than petrol models, and does not need fuel. It only needs a normal electric power supply or a good generator on site.

Dera Electric Vibrator Small Description
The Dera Electric Vibrator Small is built for fast and clean concrete compaction. It is designed to help concrete flow better into tight spaces, especially around steel reinforcement and corners of formwork. This reduces honeycombing, weak patches, cracks, and rough finishes.
It is a practical machine for small and medium construction jobs in Kenya. You can use it when casting house columns, slab edges, ring beams, water tank bases, machine bases, culverts, septic tank covers, verandas, and concrete steps.
Because it is electric, it is easier to start than a petrol engine vibrator. You do not need petrol, engine oil, or regular engine servicing. This makes it suitable for builders who want a simple machine for daily site work.
Benefits of Dera Electric Vibrator Small
1. Gives Stronger Concrete
The vibrator removes trapped air from the concrete mix. This helps the concrete become dense and strong after curing. Good vibration improves the final quality of the structure.
2. Reduces Honeycombing
Honeycombing happens when concrete does not fill the formwork properly. It leaves holes, gaps, and rough surfaces. Using the Dera electric vibrator helps the concrete settle evenly and reduces these defects.
3. Easy to Carry
The small Dera vibrator is more portable than large petrol poker vibrators. It is easier to move between columns, beams, and slab areas.
4. Good for Tight Areas
The small poker head can enter narrow spaces where big poker shafts may not work well. This is useful in columns with many steel bars and small formwork sections.
5. Lower Running Cost
Since it uses electricity, you do not spend money on petrol every day. It can run using mains power or a suitable generator.
6. Cleaner Operation
Electric models do not produce exhaust smoke like petrol concrete vibrators. This makes them better for indoor areas, closed sites, and residential work.

How to Use Dera Electric Vibrator Small
- Pour concrete into the formwork in layers.
- Insert the poker head vertically into the wet concrete.
- Allow the machine to vibrate for a few seconds in one position.

Safety Tips
Always check the cable before use. Do not use a damaged wire. Keep the motor body away from wet concrete and water. Use a stable power source with the correct voltage. Do not run the machine continuously for too long without short breaks. Wear gloves, boots, and eye protection on site.
