Reliable infiltration/exfiltration proof CMP fabrication sealant
MarMacʼs CSP Seam Seal is an alternative method to caulk or other sealants for reinforcing the hydrostatic rating of corrugated steel pipe seams. Made from highly-durable EPDM synthetic rubber, the Seam Seal cord is placed into the pipe lock seam during the CSP fabrication process. An infiltration/exfiltration-proof, gravity flow drainage system is achievable when Seam Seal is used in conjunction with our Watertight CSP Coupler.
Features & Benefits
- Reliably reinforces hydrostatic performance of seamed CSP
- Safer & more efficient than welding seams
- Easily installed
- Cost effective
- Readily available & fast shipping
CSP Seam Seal is a 3/16” premier, proprietary EPDM cord which is 50 (±5) durometer.
