Mar-flex Waterproofing & Building Products is an innovative manufacturer of waterproofing, basement and air barrier products. We supply builders and contractors with a full range of materials and equipment for lower-level-living environments. Mar-flex was founded in 1984 by Brett Oakley, a former volunteer firefighter who was concerned that many families couldn't escape their homes during disastrous situations.
We deliver superior water-based and solvent-based waterproofing membranes, with a focus on LEED certified products. We manage the building envelope as well as the below grade foundation. Mar-flex is focused on supporting you in all of your waterproofing needs. We work with you and determine which of our waterproofing systems will work best for you and your customer's.
Mar-flex Commercial Waterproofing System - Armor Series - is the solution that is setting the industry standards in Division 7 waterproofing and Section 07 27 26 fluid applied membrane and air barrier products. We deliver superior water-based and solvent-based waterproofing membranes, with a focus on LEED certified products.
Mar-flex ArmorAir Barrier 1200p vapor permeable air barrier system is designed to stop air infiltration and exfiltration in the building envelope while allowing the transmission of water vapor preventing condensation in the wall assembly. ArmorAir Barrier 1200p acrylic membrane adheres fully to CMU, concrete, exterior sheathing and most other building materials.
Joints and edges between barrier materials are at risk for water penetration. Transition strips create impermeable barriers which protect these vulnerable areas from the water. Mar-flex's ArmorFlash Transition Strips are versatile and designed for use with Mar-flex's Geo-Mat and Geo-Mat+ drainage products as well as our ArmorAir Barrier products.
