When using Trident joint sand or polymeric sand during the restoration process of a segmental pavement surface, it will ensure a durable, long-lasting performance of the system. Using a Trident joint stabilizing sealer with Trident's joint sand will stabilize (harden) the sand in the joint and protect the surface. Trident's PolySweep polymeric sand is a proprietary blend of sand and polymers and when it is activated with water will produce a semi-solid joint.
