polymer sand vs beach sand

16 years ago

The guy at the place we've ordered cement patio stones from assures me that if we use ordinary beach sand underneath and between the stones, the residual salt in it, even if the sand is washed, will destroy them, and says we should buy sand or better yet bags of a sand polymer.

We can get unlimited quantities of clean sand ourselves for free from a few miles away. It has already been 'washed' countless times by the rain and we can wash it further. Is it really necessary to buy sand - not only would it be expensive, but would have to come from the city, two hours away. Coals to Newcastle, it seems to me, but I don't want to ruin the stones.
