Guy laying concrete
block units ("Z" shaped, if you know what I mean) on flat sand ground for
driveway. But between sand and blocks guy is putting big sheets of 10? mil
plastic sheeting. Cannot explain why, just says it is good.
in this area it is common practice to put down heavy black
plastic mesh before putting down a new gravel drive - keeps the gravel from
sinking in the clay
mebbe this be a cheap version of applying the same
principle? mebbe no plastic mesh to be had ?
