Why Concrete Cover Blocks?

Why CONCRETE COVER BLOCKS?

Cover to rebar is an absolute necessity. Using various other crude methods of placing a piece of aggregate, broken tile etc are thoroughly amateurish and short lived. PVC spacers are available in the market. They are reasonably better than the crude materials that are normally used. However since PVC acts as a foreign body with concrete, it fails to essentially form a permanent bond. Hair cracks are a common predicament which leads to water vapors entering in. Concrete blocks overcome this shortcoming. It forms a permanent bond with the surrounding concrete. As the thermal coefficient of expansion is same, there are no hair cracks over the period (Ref Technical regulation work sheet W311 of German Association of Gas Hydraulic Engineers DVGW). Some companies make concrete cover blocks on site. Due to improper compaction they remain porous and do not give requisite compressive strength. We produce concrete cover blocks in controlled factory conditions where the shape, size and strength make them ideal for use.
They are cost competitive too.
