Stone Round
Rockery stone How much do I have to go round pond?
I have a pond, three meters by two meters, and want to put stone around them, usually with stones that are about 30 cm by 10 cm by 15 cm (rough estimate). Stone suppliers sold by weight. About how much do I need?
Call the place that sells the stone and get a quote. Hello — sorta their measures will not get a decent response.
