For Drainage Systems, Building Materials, and Workplace Safety

Since 1953, MarMac Manufacturing Company, Inc. has been a leading manufacturer of pipe couplings, sealants, and gaskets for underground drainage infrastructure. With hundreds of thousands of our pipe couplers in the ground since our founding in 1953, MarMac’s construction products are the highest quality, permanent sealing solutions built to stand the test of time. We have you covered with three company divisions to serve the precast concrete, corrugated metal / steel pipe, and poly / plastic pipe sectors.

Our MarMac Construction Products division, where our company started, manufactures couplings, wraps, gaskets, sealants, and more for underground, gravity flow, storm water and wastewater drain systems.

After decades of seeing our pipe couplers and wraps far outlasting the pipes and manholes to which they were applied, our MarMac Applied Infrastructure Sciences (AIS) division was founded. AIS formulates and produces polymeric coatings, concrete admixtures, and topical surface treatments for below-grade and above-grade structures. MarMac AIS is a chemical, engineering, and formulations research & development laboratory focused on extending the lifespan of the building materials our world’s infrastructure is built on.

Finally, our MarMac Protective Apparel division manufactures OSHA approved workplace safety gear and apparel for all industries. Through exclusive partnerships with some of the biggest names in personal protective equipment, MarMac Protective Apparel manufactures hazmat & coverall suits, chainsaw chaps and much more.

We proudly manufacture all of our goods right here in the United States. Located in McBee, South Carolina, we supply our high quality products to customers around the globe.
