MonoShield® delivers superior chemical resistance, durability, and fast installation for large slab-on-grade buildings, helping reduce long-term liability without slowing construction.
Robust. Chemically
Resistant. Proven.
MonoShield is a single-layer geomembrane comprised of multiple layers, including a bonded geotextile fabric and reinforcing grid to offer exceptional strength and durability during installation. MonoShield combines a metallized film encapsulated by layers of polyethylene with a spray-applied nitrile advanced asphalt seal to create a seamless barrier that sets the standard for preventing vapor diffusion and permeation. Unlike tape-based or heat-welded systems, the spray-applied seal delivers superior performance while simplifying installation. The result is a durable, cost-effective solution that helps developers reduce long-term liability and protect human health with confidence.
What is it?
MonoShield is a single-layer underslab vapor barrier system engineered for chemical resistance, durability, and fast installation. It combines MonoBase™, a metallized composite geomembrane encapsulated by layers of polyethylene, with spray-applied Nitra-Core™, a nitrile-advanced asphalt latex that creates seamless, high-performance seals at seams and penetrations.
Designed as a cost-effective alternative to traditional plastic sheet and tape-based systems, MonoShield delivers reliable vapor protection with superior constructability and long-term performance.
Is it right for my project?
MonoShield has quickly become the industry standard for large slab-on-grade buildings and warehouse developments where installation speed and budget are key considerations. It is an excellent choice for low-level vapor intrusion risk sites, voluntary preemptive mitigation strategies, or projects incorporating active sub-slab venting systems.
If you need a durable, chemically resistant barrier that installs significantly faster than conventional systems while helping reduce long-term liability, MonoShield® is a strong solution.
