Polymeric Sand
A specialized sand containing polymers that hardens when activated with water, used to fill joints between pavers.
Why It Matters for Homeowners
Why it matters: polymeric sand is what keeps a paver surface from becoming a weed garden in two years. It hardens between the joints when activated with water, locking the pavers together and preventing ant hills, weeds, and erosion. It does need replenishment every 5-10 years as foot traffic and weather wear it down. Skipping it on a new install is the most common shortcut on cheap paver jobs.
