Zero rot. Zero corrosion. Decades of performance.
Theis Septic applies Tekton polymer chemistry to septic systems, wastewater infrastructure, and underground utility installations — delivering corrosion resistance and structural integrity that standard materials cannot match. Traditional concrete septic systems crack, corrode, and fail. Steel systems rust. Theis Septic systems are lined with Tekton.
Our Tekton-lined tanks and wastewater structures are impervious to the chemical attack, moisture, and microbial corrosion that destroys conventional systems over time. The result is a septic and wastewater system that lasts decades longer with dramatically lower maintenance cost — a significant advantage for residential, commercial, and municipal customers who want to install once and forget it.
Precast and custom septic tanks with a full Tekton polymer interior lining — permanently bonded to the tank structure to prevent hydrogen sulfide attack, chemical corrosion, and microbial degradation that destroys conventional concrete tanks.
Leach field distribution pipes and structures coated with Tekton chemistry — resisting root intrusion, soil chemistry attack, and the biological degradation that shortens the effective life of conventional leach field installations.
Manholes, junction boxes, pump stations, and wastewater structures constructed or lined with Tekton chemistry — providing the long-term integrity that municipal and industrial wastewater systems require.
High-capacity septic and wastewater management systems for commercial facilities, restaurants, campgrounds, industrial plants, and institutional properties generating waste streams that rapidly degrade conventional systems.
On-site application of Tekton lining to existing septic tanks, wastewater structures, and underground utility chambers — restoring structural integrity and extending service life without full excavation and replacement.
Engineered-to-specification Tekton coating for non-standard underground utility structures — including vaults, conduit systems, electrical duct banks, and specialty subsurface infrastructure requiring long-term corrosion protection.
Theis Tekton-lined septic systems are engineered from the inside out — the proprietary polymer lining prevents corrosion, root intrusion, and structural failure for the life of the installation.

Water is the world's most precious commodity. In disaster relief areas and refugee war zones, transforming dirty and contaminated water into safe, potable drinking water is not optional — it is a matter of survival. The Parresia Clean Water System was built for exactly this.
Systems can be customized to address the risk profile of any known hazards in the target area — without limitations. Including all forms of chemical and biological warfare agents. The vehicle can be driven directly into a body of water for intake — no infrastructure required.
Ultraviolet Lights — pathogen elimination
Ozone, Oxygen & Nitrogen Generators
Organic Filters — refillable with local natural habitat materials
Independent State of the Art Power Source
On Board Testing Lab — real-time water quality verification
Ballistic/Blast Protection Package — optional for volatile environments
Revolutionary survival technology delivering cooking, warmth, clean water, and first aid capability — while remaining discreet, lightweight, and functional in the most extreme circumstances imaginable. Tested. Proven. Ready for the world.
The material has been discovered, tested, and proven in real-world conditions. The path to market is clearly defined — three steps stand between the current proven prototype and full commercial production.
Material discovered, tested, and proven in real world conditions. Final formulation requires documentation and systematization for consistent, repeatable manufacturing at commercial scale.
Independent third-party testing to validate all internal testing results. Provides credibility, regulatory pathway, and commercial confidence to buyers and distributors.
Validate packaging for safe transport under all conditions — ensuring the product reaches end users intact regardless of shipping, storage, or environmental exposure during transit.
Every Theis Septic product is engineered with or enhanced by Theis Tekton™ — our proprietary materials system proven for over 20 years in the world's most extreme environments. This gives Theis Septic a materials advantage that no competitor can replicate. Tekton's chemical resistance and adhesion properties make it uniquely suited to the corrosive underground wastewater environment where conventional linings and coatings degrade within a few years of installation.
