Learn How to Lay Blocks. Start mixing mortar mix as instructed. The first course of blocks should be installed below floor level and inside the foundation trench. This first line of concrete blocks shall rest on top of a layer of mortar mix. Spread mortar along the sides of the block and remove the excess mortar with a trowel. Repeat until the first course has been installed. Check the course with a level. Then, even it out with a thicker layer of mortar, if it is not.
Building with Block can dramatically reduce maintenance and upkeep costs. Concrete Block is more solid than other materials, and lets in 66% less exterior noise than a wood frame home. Remember, most brick or stucco homes are built over a wood frame that is much less desirable than Concrete Block construction.Concrete Block's thermal mass allows the blocks to hold in heat longer in the Winter and keep cool air inside longer in the Summer.uilding with Block can dramatically reduce maintenance and upkeep costs.
