Our Ply-Seal® foam joint seals are ideal candidates for Water and Waste Water Treatment facilities because they are closed-cell, waterproof, chemically resistant and flexible systems. Ply-Seal® prevents water absorption, minimizes chloride intrusion and allows for high movement in adverse environmental conditions.

Ply-Seal® is compatible with many different construction materials and resistant to abrasion, oxidation, oils, gasoline, salt, and other materials that may come in contact with the surface. Ply-Seal® conforms to ASTM D1056, Type 2 Class B, Grade 3 and can be bonded with our epoxy Ply-Bonder to a variety of substrates including concrete, steel, asphalt, elastomeric concrete, or wood.
