Multi-layer underslab soil gas barrier manufactured from high-grade prime virgin resins to reduce transmission of soil gases and moisture vapor. The extrusion film combines gas barrier technology with extremely low permeability to provide protection against volatile organic compounds (VOCs), methane, radon, sulfates, and other soil contaminants. Made in USA
applications
Used below interior concrete slabs on grade in commercial, residential, and industrial construction where control of soil gases and moisture vapor is required. Suitable for projects with environmental concerns, contaminated sites, or where enhanced gas mitigation is necessary.
Limitations
Not intended for applications outside below-slab gas and vapor control systems or installations that do not follow manufacturer requirements for subgrade preparation, seam sealing, and penetration detailing. Membrane performance depends on integration with a complete soil gas mitigation system where required.
Multi-layer underslab soil gas retarder manufactured from high-grade prime virgin resins to reduce migration of soil gases into building slabs. Designed as a cost-effective, preemptive solution for sites with trace levels of volatile organic compounds (VOCs), providing durable performance and long-term stability.
applications
Used below interior concrete slabs on grade in commercial, residential, and industrial construction where basic soil gas control is desired. Suitable for projects requiring preemptive mitigation of trace VOCs and general soil gas protection.
Limitations
Not intended for sites requiring full soil gas barrier performance or high-level contaminant mitigation. Installation must follow manufacturer requirements for subgrade preparation, seam sealing, and integration with other gas mitigation components where applicable.
Combined underslab physical termite barrier and vapor retarder manufactured from high-performance extruded polyolefin film with integrated termite-resistant materials. Provides continuous, non-toxic protection against subterranean termite intrusion while reducing moisture vapor transmission beneath concrete slabs and crawl space assemblies.
applications
Used below concrete slabs and in crawl space construction where both termite protection and moisture vapor control are required. Suitable for residential, commercial, and institutional projects following integrated pest management strategies.
Limitations
Not intended for applications requiring chemical termite treatment in lieu of physical barriers or installations that do not follow manufacturer requirements for continuity, seam sealing, and detailing at penetrations and foundation interfaces. Performance depends on maintaining a continuous barrier system.

| - | Stego 10-MIL Class A or C | Stego Industries
10-mil underslab vapor retarders manufactured from proprietary blends of prime virgin polyolefin resins and additives to reduce moisture vapor transmission through concrete slabs. Available in Class A and Class C performance levels to accommodate varying project requirements, both providing improved durability and resistance to deterioration compared to generic recycled polyethylene films. Class A membranes also support mitigation of soil gases such as radon and methane. Class A exceeds ASTM E1745 Class A, B, and C requirements; Class C exceeds ASTM E1745 Class C requirements. Made in USA
applications
Used below interior concrete slabs on grade for moisture vapor control and protection of moisture-sensitive floor finishes. Suitable for commercial, residential, and institutional construction. Class A is used where enhanced puncture resistance and optional soil gas mitigation are desired, while Class C provides an economical option for projects with lighter construction demands.
Limitations
Not intended for applications other than underslab vapor control or installations that do not follow manufacturer requirements for subgrade preparation, seam sealing, and protection during placement. Class C membranes are not recommended where higher puncture resistance or maximum vapor performance is required.
20-mil underslab vapor barrier manufactured from a proprietary blend of prime virgin resins and additives in a multi-layer extrusion film to provide enhanced resistance to moisture vapor and soil gas transmission. Increased thickness and durability make it suitable for demanding applications requiring maximum protection against moisture intrusion and construction-related damage. Reference Standards: Exceeds ASTM E1745 Class A, B, and C requirements. Made in USA
applications
Used below interior concrete slabs on grade in commercial, residential, and industrial construction. Suitable for moisture-sensitive environments and critical facilities such as healthcare, laboratories, and data centers where enhanced vapor protection is required. Helps reduce risk of flooring failures and mitigates soil gases including radon and methane.
Limitations
Not intended for applications other than underslab vapor control or installations that do not follow manufacturer requirements for subgrade preparation, seam sealing, and protection during concrete placement. Proper detailing at penetrations and terminations is required to maintain performance.
15-mil underslab vapor barrier manufactured from a proprietary blend of prime virgin resins and performance additives to reduce moisture vapor and soil gas transmission through concrete slabs. The membrane provides extremely low permeability, wide roll widths to minimize seams, and compliance with ASTM E1745 Class A, B, and C requirements.
applications
Used below interior concrete slabs on grade to protect moisture-sensitive floor finishes and building assemblies. Suitable for commercial, residential, and institutional construction where control of vapor transmission and soil gases is required. Wide 14-foot rolls reduce field seams and support efficient installation.
