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.
