What Polymeric Sand Does
Unlike standard jointing sand, polymeric sand contains binding agents that harden when activated with water, locking pavers in place, resisting weed intrusion, and reducing sand washout during North Texas's often intense spring downpours.
DFW-Specific Considerations
Expansive clay soil beneath many North Texas paver installations can shift seasonally, putting additional stress on jointed sand compared to more stable soil types. Heavy rain arriving too soon after installation, before the sand has fully cured, can also wash out joints.
Maintenance After Installation
Pressure washing pavers with polymeric sand joints requires lower pressure and more careful technique than standard sand, since aggressive pressure washing can erode even cured polymeric joints over time.
