GCP, a leading global provider of high-performance specialty building materials, proudly announces the launch of PREPRUFE® SCS Plus, the newest innovative enhancement to their PREPRUFE SCS waterproofing system, which is engineered specifically to withstand the force of shotcrete placement on foundation walls.
Designed for below-grade blindside applications, PREPRUFE SCS Plus delivers simplified installation, time savings, redundancy in protection, and a significant upgrade: It now meets the methane barrier requirements outlined in the Los Angeles Research Report (LARR) under LADBS AC-L137 for waterproofing systems in shotcrete applications adding values to all project stake holders.
“PREPRUFE SCS Plus demonstrates GCP’s continued focus on evolving core products to simplify installation, reduce errors, meet changing regulatory requirements and installation realities,” says GCP Senior Product Manager Iltaz Alam. “This new membrane provides specifiers and contractors with a robust, easy-to-install solution for high-risk below-grade shotcrete walls, particularly in regions like Southern California where methane mitigation is critical.”
GCP’s patented PREPRUFE SCS Plus system consists of three integrated components engineered to work together:
PREPRUFE SCS Plus Membrane – The upgraded membrane features a polymer mesh-reinforced cavity with a durable composite film on the soil-facing side and a non-woven, semi-permeable geotextile on the concrete-facing side. This unique configuration promotes strong bonding to shotcrete while creating a cavity for post-injected grout to form a uniform, monolithic waterproofing layer restricting water migration and filling voids and cracks developed due to shotcrete application.
PREPRUFE SCS Grout Injection Ports – Installed prior to shotcrete placement, these ports facilitate targeted, pressurized post injection of grout into the membrane cavity after the shotcrete is in place.
PREPRUFE SCS Hydrophilic Grout – Uniquely designed, water-reactive grout injected post-shotcrete through the ports to fill the cavity, creating a continuous barrier that seals the system and eliminates lateral water migration.
Unlike conventional waterproofing systems for shotcrete walls, the PREPRUFE SCS system creates an in-situ grout layer with consistent thickness, delivering superior protection and durability, while the injected grout actively seals the structure.
PREPRUFE SCS Plus reflects GCP’s ongoing commitment to advancing proven technologies and developing next-generation solutions to solve problems for customers and continuously delivering value
Leading the innovation in the waterproofing industry, in the past year, GCP has introduced PREPRUFE Liquid Flashing for simplified pre-applied details and PERM-A-BARRIER® Ultra™ Wall Membranes and Flashing for high temperature stable application. Additional advanced solutions are currently beta testing.
