Complete Guide on How to Install Bondek

Bondek is a floor or roof covering material made of galvanized steel and functions as a permanent formwork as well as positive reinforcement. Its use in construction projects can speed up work and increase the durability of the structure. For maximum installation results, here is a complete guide on how to install bondek correctly.

Tools and Materials Needed

• Bondek - Choose the thickness that suits the project needs.
• Wiremesh Iron - To strengthen the concrete structure.
• Reinforcement Iron - As additional reinforcement.
• Cast Concrete - For floor casting.
• Screws or Nail Guns - For installing bondek to the steel frame.
• Cutting Tools (Grinder or Iron Scissors) - To adjust the size of the bondek.
• Waterpass & Meter - To ensure even and precise installation.

Bondek Installation Steps
Prepare the Supporting Structure

• Make sure the steel frame or concrete beam is firmly installed.
• Make sure the structure is flat using a waterpass so that the bondek installation is precise.

Install Bondek with the Correct Pattern

• Place the bondek sheet on the steel frame or beam.
• Make sure each sheet of bondek overlaps about 5 cm to prevent concrete leakage during casting.
• Arrange in a straight pattern so that the final result is neat.

Lock Bondek with Screws or Nail Guns

• Use special light steel screws or nail guns to attach bondek to the steel beam.
• Install screws in each wave of bondek that is attached to the beam to ensure maximum strength.

Install Wiremesh Iron for Additional Reinforcement

• Place the wiremesh on top of the bondek with the help of spacers so that it does not stick directly to the bondek surface.
• Make sure the wiremesh has a distance according to the structural calculations to support the concrete.

Perform Concrete Casting

• Prepare the concrete mixture according to the required specifications.
• Pour the concrete slowly and evenly over the entire surface of the bondek.
• Use a concrete vibrator to remove air cavities so that the casting results are denser and stronger.

Let the Concrete Dry Properly

• Let the concrete dry for at least 7 days to gain initial strength.
• Water it regularly so that the concrete does not crack due to drying too quickly.

Tips for More Effective Bondek Installation

• Use high-quality bondek so that it does not bend easily when stepped on.
• Make sure the screw installation is strong and even to avoid shifting during casting.
• Recheck the bondek height level before casting to ensure a flat surface.
• Perform maintenance after casting by sprinkling water to make the concrete stronger.

Conclusion
Bondek is a practical solution for stronger and more efficient concrete floor or roof construction. By following the correct installation steps, the results will be neater, stronger, and more durable.
