Whats the difference between joint sand and polymeric sand?
Joint sand is the most commonly used material between the joints of tumbled pavers by most companies/installers, however, it can easily be blown out from the joints or washed away from rain. Polymeric sand has a bonding agent and as it gets wet and dries the sand bonds hardening the sand, preventing any loss of sand as well as helping in the prevention of weed growth. If the bond where to crack, a little water would soften the sand, allowing it to reform solid again. Dream Home Exteriors, Inc. exclusively uses polymeric sand on all of their tumbled patio jobs.
