that using a coarse concrete sand or stone
sand as a setting bed. Stone dust or limestone screenings is not recommended since it does not allow water to drain which cause rutting and settlement.
Can somebody comment on the information.
Also what is the difference of using
"gravel of limestone" and "crush concrete stone" as the aggregate base.
One contractor discouraged me from using
crush concrete stone since he said that
the crush concrete stone might mix up with
gabage and other dirt.
