Step Ten When here all blocks are in location, brush down the driveway to eliminate any kind of busted items of block or particles to guarantee they do not come down the joints between the block paving.
Brush kiln dried out sand over the whole location making sure all the joints are full to the top. Provide them a condensing with the plate compactor, leave surplus sand on top of the the driveway so when the vibrating plate passes over it, it will spread around loading any kind of joints which could need more sand.
