Need your assistance with paving within a 3.7 x 5.4 hardwood sleeper box.
I'm a first time paver and am trying to pave 400mm x 400mm x 50mm Boral pavers level with the top row of sleepers.
My problem is calculating to what height I need to lay the sand for the pavers to be compacted down to meet the lip of the sleepers.
Roughly 1500mm will be compacted road base with sand to follow.
Will different sands compact more than others under the weight of the paver? If so what sand is best for this job?
I live in the North-Western suburbs of Brisbane/Pine Rivers.
Further, 100mm grinder with a diamond tip blade appropriate to get through these 50mm pavers?
