The stone will then be a lot more compact and providing it higher strength. Obviously, there are other things to consider, like the proper depth of stone wanted for that type of task/bodyweight the stone will carry. Furthermore the ground the stone are going to be laid on.
Residual mortar articles causes decrease strength and poorer prolonged-term functionality. Higher h2o absorption cuts down sturdiness.
