Polymeric sand or concrete for paver joints?
Choosing between polymeric sand and concrete comes down to whether you want a flexible joint material that resists weed growth or a rigid edge that locks pavers firmly in place. This uncertainty often halts patio and walkway maintenance projects because homeowners worry about cracking, shifting, or choosing a material that won't hold up to weather.
