Description

MarMacʼs CMP Coupler is a single unit, external sealing band designed to prevent infiltration into corrugated steel pipe drainage systems. The coupling creates a strong, permanent, flexible seal around the joints of rerolled (annularized) or non-rerolled (spiral) CSP pipe ends.

CMP couplers function on traditional galvanized and polymer coated pipe. They are easy to install, cost-efficient, permanent, and readily available. Our dedicated production line and unique manufacturing process allow for quick shipping regardless of coupler size or order quantity.

MarMac CMP Coupler membranes are constructed of cross-laminated layers of rubberized mastic, integrated mechanical compression bands, an internal woven reinforcement, and butyl underlays.

Our proprietary mastic aggressively adheres to the pipe surface, while the integrated compressions bands mechanically seal and form a permanent bond to the full circumference of the pipe walls. The internal woven polypropylene material provides increased shear and puncture resistance. The butyl rubber underlays compress beneath the compression bands and against the pipe wall and joint, forming an infiltration-proof seal on annular, spiral or helical corrugations.

Available in all sizes to connect virtually any diameter of corrugated metal pipe, Soil-Tight CMP Couplers seal both rerolled and non-rerolled pipe ends. They are designed with four evenly-spaced, high-tensile compression bands, each reinforced with butyl rubber underlays. When the bands are tightened, the compressed butyl creates an infiltration-proof, exfiltration-resistant joint.

SPECIFICATION

CMP Couplers integrate several unique components into a single, full-perimeter, external sealing band. The coupler composition consists of:

  • Heavy duty polyethylene backing
  • Internal woven polypropylene reinforcement
  • High-tensile compression bands
  • Specially formulated mastic contact layer with butyl sealant underlays

INSTALLATION

The coupler shall be placed around the pipe, mastic side to the pipe, spanning the joint. The protective release film shall be removed and the coupler applied with the overlap at the top of the pipe. The straps shall be secured (outside straps first) on the larger outside diameter pipe (when applicable) with the proper tools; the securing straps on the outside of the smaller outside diameter pipe shall then be secured. The inside strap shall be tightened last. The closing flap shall cover the exposed strap work area, completing the joint.
