Pouyagostar Tunneling Industry Elastomer Gasket – 388.6 mm²

Pouyagostar Tunneling Industry Gaskets are engineered elastomer sealing components designed to provide long-term watertightness in segmental tunnel linings. Installed in continuous grooves within reinforced concrete tunnel segments, these gaskets seal longitudinal and T-joints, helping prevent water ingress under the pressure conditions encountered in tunneling projects.

Manufactured using high-grade rubber compounds, Pouyagostar gaskets are designed to meet demanding requirements for durability, sealing performance, and tunnel service life. Their specially engineered cross-sectional profile allows the gasket to compress as concrete segments are assembled, creating a reliable seal while helping minimize the forces required to close the joints. The compression also helps accommodate gaps and offsets between adjacent segments.

With 10 years of experience in developing and manufacturing elastomer gaskets for the tunneling industry, Pouyagostar offers solutions for a range of tunnel lining applications. Its technical engineering team can also develop gasket designs for specific project conditions and carries out testing to evaluate sealing performance under simulated assembly conditions and water pressure.

Pouyagostar's laboratory and production-line quality certification follows the STUVA recommendations for testing and application of sealing gaskets in segmental linings, supporting quality assurance for demanding tunneling projects.

This gasket has a cross-sectional area of 388.6 mm² and is suitable for consideration in tunnel segment sealing applications where the gasket profile and performance must meet project-specific engineering requirements.
