Born from Science
Instead of asking, "Which vapor retarder should we specify?" Hygrothermix asks, "What slab moisture outcome are we trying to achieve?"
That question led to more than two years of science-based research, advanced hygrothermal modeling, and engineering analysis. The results challenged many conventional assumptions. We discovered that long-term slab moisture performance depends on the interaction of the entire under-slab assembly—not simply on maximizing individual vapor retarder properties such as permeance and thickness.
Those discoveries became the foundation of the SlabTECK® system of vapor retarders and accessories. Every product is designed to function as part of an engineered moisture control system, not as a standalone commodity. At Hygrothermix, our products are the outcome of our research—not the starting point.
Through project-specific hygrothermal engineering, Hygrothermix evaluates and compares alternative under-slab assemblies over decades of building operation. This allows project teams to optimize system design, reduce unnecessary construction costs, and make informed engineering decisions before construction begins. The resulting SlabTECK® system is engineered to deliver predictable slab moisture performance.
We don't simply manufacture vapor retarders. We engineer predictable slab moisture outcomes.


The SlabTECK Family of Products:





TECKFilm
TECKTape
TECKSeal
TECK2BND
Because bonding to low-surface-energy films (like blown PE vapor retarders) in construction environments can present significant challenges, we don't rely on relabled, generic accessories. We design and/or manufacture our tapes/sealants and chemistry-match them with our films to create the strongest bonds possible. Our decades of field experience and R&D demonstrate proper installation as key to the long-term moisture protection efficacy of your slab.
Better adhesion, better instalation, better results.


Because Hygrothermix is vertically integrated in key areas of manufacturing and operate with a streamlined supply chain, we eliminate middle layers and deliver higher-quality materials at lower cost. SlabTECK is more than just products—we provide confidence that your building is efficiently and economically protected from the ground up.
Integrated & Efficient Supply

We're With You From Design To Installation & Review
Hygrothermix supports every project with slab assembly design assistance, pre-slab meetings, real-time technical assistance, construction shop drawings, digital/in-person installation reviews, and predicted performance results ensuring that each system is installed correctly and performs as designed. Using advanced hygrothermal modeling, we help you predict slab moisture performance before construction even begins, and we back it up with design-assistance documentation or as-built reports that detail system performance for decades to come. From science to slab, the SlabTECK product family delivers a smarter, safer, and more cost-effective approach to concrete slab vapor control.


Who We Are...
Hygrothermix was founded on more than two decades of experience in building science, materials engineering, construction innovation, and advanced manufacturing. Long before the company was formed, our team was developing patented technologies, contributing to ASTM standards, supporting under-slab installations, and applying advanced hygrothermal modeling to better understand how heat and moisture interact within concrete slab systems.
Our research led to a simple but important conclusion: the long-term performance of a concrete slab is governed by the behavior of the entire under-slab assembly—not by the vapor retarder alone. That discovery became the foundation of the SlabTECK® system, combining predictive engineering, scientifically designed products, and practical installation methods into a complete under-slab moisture control solution.
Today, Hygrothermix combines engineering, manufacturing, and field experience to help project teams make informed decisions before construction begins. Through predictive hygrothermal modeling, system design assistance, high-performance products, and technical support, we help optimize under-slab assemblies for long-term moisture performance while improving constructability and controlling project costs.
We don't simply manufacture vapor retarders—we assist in engineering predictable slab moisture outcomes.
