Dry Stack Block Wall

Before applying the surface bonding cement dampen the surface of the block.
Dry stack block wall. Second ordinary block is usually grouted filled with concrete when the wall is complete in only the cells containing reinforcing steel rebar while dry. This will aid in the adhesion of the material to the block and will also eliminate the otherwise dry block from pulling the moisture out of your surface bonding cement mix. They also fill every block cell with sand or concrete to improve the thermal mass of the wall. Throughout the block stacking phase and at the completion check that the wall has remained level.
Blocks should be laid in. The first course of dry stack block should be placed on a smooth level bearing surface of proper size and strength to ensure a plumb and stable wall. A dry stack wall is a block wall that doesn t need mortar to hold it together. Minor roughness and variations in level can be corrected by setting the first course in mortar.
Earth bermed and thermal mass homes often use dry stacked wall construction because of its convenience. Figure 2 basic dry stack masonry wall types. This mortar joint at the base lets you set the first course absolutely level. The outside temperature spikes and plunges are buffered by this block wall mass in conventional homes.
Step 7 thoroughly dampen the block wall with water dry block will draw the water from the mix making it difficult to finish and can cause inconsistent color and cracking especially in. The rest of the dry stack block courses are laid without need for any mortar between blocks as long as they are of uniform size. With dry stack construction only the first course is bedded in grout on the footer to establish plumb and level for the wall. First the dry stack method uses mortar only at the joint between the footing and the first course of block.
