Step Ten When all blocks remain in area, brush down the driveway to eliminate any kind of broken items of block or particles to ensure they don't come down the joints in between the block paving.
Brush kiln dried sand over the entire location making certain all the joints are complete to the top. Then give them a condensing with home plate compactor, leave excess sand on top of the the driveway so when the vibrating plate overlooks it, it will certainly spread out about loading any kind of joints which may need more sand.
