Metazeal AJ – Expansion Joints

Metazeal AJ – Expansion Joints

Metazeal AJ is a pre-formed, closed cell, low-density, cross-linked EVA/PE (Ethyl Vinyl Acetate-Polyethylene) foam joint seal. The material is typically used as an expansion joint seal or as a gasket material in a bridge, commercial building, parking, water treatment facility and other industrial applications. When installed within the CEVA® Joint Systems, the material acts as a water tight seismic expansion joint seal. Additional features include applications in hydrostatic environments. Metazeal AJ can be installed in ponding/standing water and is safe for use in potable and processed water applications. Metazeal AJ meets ADA criteria for ground and floor surfaces as stated in the rules and regulations section of the Federal Register Volume 58 no. 144, US Access Board.
