Weed-Blocker Polymeric Joint Sand Nurserymen’s Preferred Weed-Blocker™ is a specially formulated polymer modified joint sand for use with pavement systems utilizing segmental concrete pavers, clay pavers or natural stone; concrete slab joint applications or filling gaps between segmental retaining wall blocks. Typical applications include stabilizing horizontal or sloping projects such as driveways, sidewalks, concrete slab joints, patios, pool decks, gaps between segmental retaining wall blocks, roadways and traffic areas-both residential and commercial. Weed-Blocker™ becomes activated when combined with water. The individual sand particles will bind together and set firm while remaining flexible to allow for movement in the pavement system. Loosened material will bind again once exposed to a moisture source.
