CONCRETE COVER BLOCKS

CONCRETE COVER BLOCKS:
Using Concrete Cover Blocks is adhering to good practices in Construction and provides better bonding with
surrounding concrete as it is of same material.

A cover block is a spacer that is used to lift the rebar matrix (jali) off the ground for slabs and similarly for beams and
columns a space is created between the shuttering and reinforcements so that concrete may flow underneath and
around to become a permanent and integral part of the poured concrete

Cover Blocks should be placed by ensuring that uniform cover is available providing adequate concrete coverage
during the pour.

• To protect the reinforcements from environmental effects to prevent corrosion.
• To provide thermal insulation, this protects the reinforcement bars during fire.
• To give reinforcing bars sufficient embedding to enable them to be stressed without slipping.
