Screenings: What are they?
Screenings are most commonly used as a setting bed and joint filler for pavers. This is because of its compaction properties that help form a sturdy, non-porous upper layer that protects from moisture seeping into the base layer. The interlocked screenings will also prevent weed and grass growth from sprouting up between pavers.
