I'm currently installing a 22x16 paver patio with the help of a contractor. When he called the gravel place to get the stone for the base, they said that instead of doing gravel and then sand it wold be better to just put a 6" layer of heavily compacted torpedo sand. Is this really the right way to do it?
Im in WI so we have a bad frost/thaw cycle and its heavy clay ground.
Since the sand is being delivered tomorrow I need some suggestions quickly.
I wouldn't but then again I have never heard of tropedo sand. I have installed many a sq. ft of paver, professionally. I have never used strictly sand. 7 inch base and a 1.5 inch sand. We use what is called 2NS sand for screed base.
