Granite Base RoundDescription Black parasol base 40kg. Our stylish and high quality parasols deserve just as good a parasol base. We dont just recommend a granite parasol base just for its looks, but also for use with a parasol with a large cloth surface which needs a heavy base to stand solid. It is a beautiful natural stone and heavy in terms of specific weight. Granite has a high density; with relatively little granite you can still make a heavy parasol base.
