Gaskets & Sealants

MarMac offers sealing solutions and gaskets for all the major infrastructure industries. Use our C-990 ASTM-rated Butyl Sealant when connecting box culverts, manhole sections, and more. Its tacky, rope design seals off joints and assists with the elimination of infiltration/exfiltration.

Use MarMac CSP Seam Seal in the pipe fabrication process to seal off your CMP seams. Our CSP Coupler can be used in conjunction with Seam Seal for true hydrostatic performance. See below for all of our gaskets & sealants.
