Why Use Cover Blocks | HANSIKA POLYMERS

WHY COVER BLOCKS ARE USED IN REINFORCEMENT?

A Cover Block is essentially a spacer that is used to lift the rebar matrix off the ground so that concrete may flow under the rebar.

To maintain a specified distance between the rebar and the shuttering.

To protect the steel reinforcement bars from environmental effects to prevent their corrosion.

To provide thermal insulation, which protects the reinforcement bars from fire.

To give reinforcing bars sufficient embedding to enable them to be stressed without slipping.

Thus using cover blocks enhances the life of the structure significantly without adding much to the cost.
