Trusted Waterproofing Solutions by Tegraseal Products
Tegraseal Products was founded in 2008 by Bryan McGroarty, the original inventor of bentonite-on-HDPE waterproofing technology. Our company continues the legacy of innovation that began with Bryan's patented waterproofing membrane in 1986, which set industry standards for effectiveness and reliability. We specialize in high-performance bentonite waterproofing systems and construction joint waterstops designed for demanding applications including backfilled walls, blindside installations, underslab floors, decks, tunnels, and green-roof projects. Our team provides comprehensive support through design assistance, approved applicator networks, and independent inspections to ensure complete waterproofing solutions.With decades of combined experience in construction materials science, we leverage the unique properties of sodium bentonite clay to create self-sealing, multi-layered protection systems that offer century-long durability. Our products combine the natural sealing capabilities of Wyoming-mined bentonite with high-density polyethylene membranes to form waterproof barriers that self-repair minor damage while maintaining structural integrity under hydrostatic pressure. We serve commercial construction projects nationwide, offering technical resources including architectural specifications, detailed drawings, and safety data sheets to support successful implementation of our systems.

TegraTite Waterproofing Membrane
TegraTite combines bentonite clay with 20-mil HDPE to create a self-sealing waterproofing membrane. The sodium bentonite layer expands when wet, forming a molecular barrier against water intrusion while the HDPE layer provides structural protection. Ideal for backfilled walls and hydrostatic conditions, this system offers permanent protection through dual-layer technology that maintains effectiveness for centuries.
TegraTite Plus
TegraTite Plus features bentonite, HDPE, and a protective polypropylene layer for blindside applications. Designed for lagging, elevator pits, and underslab installations, its protective layer withstands construction site stresses. The membrane's flexibility allows easy installation before concrete pouring while maintaining durability against weather exposure and direct shotcrete application.
TripleSeal Membrane
TripleSeal provides three waterproofing layers in one product: bentonite on both sides of HDPE with protective polypropylene. This configuration creates waterproof bonds to both concrete surfaces and external insulation. Particularly effective in elevator pits and critical waterproofing zones, it prevents thermal bridging while maintaining structural integrity through its multi-layer protection system.
CureTite Adhesive
CureTite is a water-based mastic containing 15-20% bentonite for sealing cracks and transitions. Its malleable formula allows easy application in concrete joints and pipe penetrations. Available in tubes and pails, this adhesive forms permanent seals in both new and existing construction projects while maintaining compatibility with other waterproofing materials.
WaterStop Systems
TegraSeal WaterStop provides multilayer protection for concrete construction joints. This bentonite-based strip prevents water migration in footings, walls, and decks while maintaining flexibility under extreme water pressure. The system forms permanent seals in static joints, making it ideal for tunnels, parking structures, and plaza decks requiring long-term joint waterproofing solutions.

Questions
Do TegraSeal products contribute to LEED or GreenGlobe certifications?
Yes, our products can contribute to multiple LEED and GreenGlobe points. Contact us for specific project requirements.
Can TegraSeal be used in saltwater environments?
We recommend submitting a water sample for testing before saltwater applications to ensure product suitability.
What makes TripleSeal different from other membranes?
TripleSeal uniquely combines bentonite on both sides of HDPE with protective layers for three waterproofing layers in one product.
Can your products be used for existing waterproofing repairs?
Yes, all TegraSeal products work in both new construction and existing waterproofing repair applications.
How does bentonite self-seal concrete cracks?
Sodium bentonite expands when wet, creating internal pressure that seals cracks and prevents water migration through concrete structures.
What temperature ranges allow product installation?
Most products install in extreme temperatures, though CureTite requires non-freezing conditions during application.
