Metazeal AJ-s

Metazeal AJ-s is a pre-formed closed cell, low-density cross-linked EVA/PE (Ethyl Vinyl Acetate-Polyethylene) foam joint seal. This material is typically used as an expansion joint seal or gasket in bridge decks, commercial buildings, parking decks, water treatment facilities, and other industrial applications. When installed within the Ceva Joint Systems, this material acts as a water tight, seismic expansion joint seal.

Additional features include applications in hydrostatic environments. This material can be installed in ponding/standing water.

Metazeal AJ-s material is safe for use in potable and processed water applications.

Metazeal AJ-s 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.
