Adding Sand Between the Pavers

Q: Is it necessary to add sand between the pavers of a flexible-base patio?

A: According to the experts at Pine Hall Brick, joint sand is the key to providing interlock between pavers and providing cushion between the pavers to prevent paver-to-paver contact and chipping. The sand joint between pavers should be between 1/16 and 3/16 inch. Concrete sand that has coarse and angular particles is recommended over masonry sand, which has rounder, finer particles. The joints need to be completely full of sand to function properly and promote interlock in the system. If the sand joints between your pavers are not full then it is important to add more sand to prevent pavement failure. A properly installed base and edge system that drains properly will go a long way towards maintaining full joints. Learn more about landscape pavers at www.pinehallbrick.com.
