LIQUID BOOT® Vapor Barrier

At Radon Defenders, we’re committed to using the most advanced and effective vapor mitigation technologies available—which is why we utilize the LIQUID BOOT® Vapor Barrier system from CETCO as part of our comprehensive vapor intrusion mitigation services. When chemicals and contaminants are present in the soil or groundwater near a structure, harmful vapors can migrate into the building and compromise indoor air quality. These vapors—including volatile organic compounds (VOCs) and other toxic substances—can pose serious health risks to occupants.

To combat this, we install LIQUID BOOT®, a seamless, spray-applied membrane that forms an airtight barrier between the soil and structure. This cutting-edge solution is trusted globally, with over 50 million square feet installed in critical environments such as hospitals, schools, libraries, multi-family residences, commercial facilities, and public infrastructure projects. As certified mitigation specialists, Radon Defenders integrates LIQUID BOOT® into our system designs to provide long-lasting, proven protection against vapor intrusion—safeguarding both the health of occupants and the integrity of your building.

Benefits of LIQUID BOOT®

Spray-applied LIQUID BOOT® Vapor Barrier can be installed in various climates on the most complex structural shapes, and penetrations without nailing, special mastics, or tape/welded seaming. With its rubberized asphalt forming the installation’s core, it bonds securely to most construction materials to create a flexible, seamless barrier that accommodates significant stretching. Chemically resistant LIQUID BOOT® Vapor Barrier features low permeability to gases and vapors while blocking non-hydrostatic nuisance water.

What are the Benefits of The LIQUID BOOT® Vapor Barrier

• Seal out contaminated vapors with our chemically resistant technologies.

• Trust in our network of certified installers and inspectors for expert installations.

• Join over 50 million square feet of successful installations worldwide on prestigious projects.

Quality Assurance with Liquid Boot

Radon Defenders, we are proud to work in conjunction with CETCO’s LIQUID BOOT® Vapor Barrier System to deliver industry-leading vapor intrusion protection for residential, commercial, and industrial projects. As certified installers and inspectors of CETCO systems, we follow rigorous quality assurance and quality control (QA/QC) protocols to ensure every installation is gas-tight, durable, and effective.

One of the key components of our installation process is smoke testing—a proven method pioneered by CETCO and now recognized as a best practice across the industry. During this test, smoke is pumped beneath the vapor barrier membrane to identify even the smallest imperfections or holes. Any defects detected are immediately repaired on-site, guaranteeing a continuous, sealed vapor barrier system that meets or exceeds engineering and environmental standards.

With CETCO’s global reputation and innovation in vapor intrusion solutions—and our team’s hands-on expertise and certification—Radon Defenders ensures every LIQUID BOOT® installation is performed with precision and accountability. Whether you're protecting a healthcare facility, school, multifamily development, or commercial space, we deliver fully tested, certified vapor mitigation systems you can trust to safeguard air quality and occupant health.

LIQUID BOOT® and LIQUID BOOT® 500

At Radon Defenders, we proudly utilize LIQUID BOOT® and LIQUID BOOT® 500 gas vapor barrier systems—seamless, spray-applied, water-based membranes designed to create a durable, fully adhered barrier that blocks harmful vapors like radon, methane, and VOCs from entering buildings. These systems are especially effective for methane and radon migration control, with applications under slabs and below-grade vertical walls in both residential and commercial settings. With an 80-mil thickness, LIQUID BOOT® also helps minimize nuisance water migration under non-hydrostatic conditions. Its spray application ensures thorough coverage across penetrations, footings, and structural elements without mechanical fastening, reducing the risk of failure common with traditional seamed membranes.

The benefits of this system are unmatched: its monolithic membrane eliminates seaming issues, offers zero permeability to radon (as verified by the U.S. Department of Energy), and provides superior resistance to methane and water vapor. LIQUID BOOT® is ideal for use in schools, hospitals, multi-family housing, and commercial projects where air quality and environmental safety are critical. As certified installers, Radon Defenders ensures expert application and smoke-tested verification, delivering a high-performance vapor intrusion solution that meets the highest standards in the industry.

LIQUID BOOT® PLUS and LIQUID BOOT® 500 PLUS

At Radon Defenders, we also offer advanced protection with the LIQUID BOOT® PLUS and LIQUID BOOT® 500 PLUS systems—premium gas vapor barrier solutions designed for the most demanding vapor intrusion scenarios. These systems combine the proven performance of the spray-applied LIQUID BOOT® membrane with the cutting-edge VI-20™ geomembrane, a 7-layer co-extruded barrier engineered for superior resistance to VOC (volatile organic compound) transmission. This dual-layer approach provides unmatched protection against chlorinated solvents, methane, radon, BTEX compounds, and other harmful contaminants. Installed under slabs and below-grade walls, these systems are ideal for non-hydrostatic conditions where vapor and nuisance water migration are a concern.

With 40 mils of LIQUID BOOT® and an additional 20 mils of VI-20™, this system delivers outstanding resistance to punctures, tears, and diffusion of harmful gases and chemicals. Laboratory-tested performance shows VOC diffusion coefficients up to 20 times lower than traditional HDPE liners, offering a significant safety advantage for high-risk sites. At Radon Defenders, our certified team ensures each system is expertly applied, fully adhered, and quality-controlled for maximum effectiveness. Whether protecting a commercial site, multifamily development, or sensitive facility, our vapor mitigation installations with LIQUID BOOT® PLUS provide the ultimate defense for clean indoor air and structural safety.

GeoVent™ Gas Venting System

At Radon Defenders, we proudly offer the GeoVent™ Gas Venting System as part of our advanced radon and vapor mitigation solutions. This innovative, low-profile system is designed for both active and passive under-slab venting applications and is ideal when paired with CETCO vapor barriers. Unlike traditional methods that require extensive trenching, GeoVent™ installs directly on the subgrade—reducing installation time, minimizing disruption to underground utilities, and placing the vent system closer to the source of vapor for more effective gas capture.

With a 4" outlet connection and high-efficiency filter fabric, the GeoVent™ system provides greater airflow per linear foot of pipe, improving overall venting performance. It meets rigorous ASTM standards for strength, permeability, and durability, ensuring long-term reliability. Whether you're building new construction or retrofitting an existing site, Radon Defenders uses GeoVent™ to deliver safe, cost-effective, and code-compliant vapor mitigation you can trust.
