sorry to be a bore, but this coarse sand malarky to which you referred ......... where might i find said product.
when googling i'm either finding the stuff to mix concrete with or laying paving slabs on and i'm sure i don't want that, or the stuff to put in sand pits and i'm sure i don't want that either.
there are lots of references to coarse sand, but very little about suppliers.
am i heading to a builder's merchant, a garden centre or b&q ?
thanks in advance.
