The benefits of
SeamSeal are clear
Superior Joint Protection
Fills gaps and creates a durable barrier at cold joints, centerlines, and edges.
Flexible, Durable, Safe
Expands and contracts with the pavement to resist cracking. Bio-based and non-toxic.

Built for Pavement Longevity
From highways to runways, SeamSeal ensures that your pavement performs better for longer. Protect your investment at its most vulnerable point—the joint.

How SeamSeal Works
When applied to asphalt seams, SeamSeal penetrates and bonds the adjoining surfaces. Its polymer-enhanced formula remains flexible over time, accommodating seasonal expansion and contraction while keeping moisture out. This prevents raveling, stripping, and joint separation—major causes of early pavement failure.
