[Talk to An Expert](https://www.laurencowaterproofing.com/talk-to-expert?hsLang=en) ![RMA-hero](https://www.laurencowaterproofing.com/hs-fs/hubfs/RMA-hero.jpg?width=997&height=815&name=RMA-hero.jpg) ![rma-right](https://www.laurencowaterproofing.com/hs-fs/hubfs/rma-right.jpg?width=449&height=449&name=rma-right.jpg) THE RMA SYSTEM ## Built for the toughest conditions ### The Laurenco RMA system’s speed and ease of installation keeps projects on schedule. No need for expensive and dangerous hot asphalt kettles, melters, or torches. The Laurenco RMA System is a versatile waterproofing solution suited for a wide range of applications, including below-grade foundations (including blind-side), plaza decks, planters, roofing assemblies (IRMA, vegetative, and exposed), fountains and pools, bridges, tunnels, power plants, and dams. This two-ply system begins with the application of rubberized Laurenco Adhesive over a properly prepared substrate. The first course of Laurenco Roll is embedded into the tackified adhesive and subsequently coated with an additional layer of Laurenco Adhesive. A second course of Laurenco Roll is then installed to complete the two-ply assembly. The Laurenco Adhesive acts as a chemical bonding agent with the Laurenco Roll, allowing the materials to assimilate and form a fully bonded, monolithic waterproofing system. ### Download the RMA System Installation Guide Learn more about our high-quality, easy-to-apply RMA waterproofing system engineered for reliable performance.
