· The holes occupy between 2550% of the total volume of the block. Hollow concrete blocks are used as conduits for electrical wiring, plumbing pipes, and HVAC piping. Due to the hollows, the thermal and sound insulation properties of these bricks are very good, and they also require less concrete mortar or plastering compared to solid blocks.
