Tech Patch Repair System | Permanent Repair of Poly & Metal Tanks & Pipes
Highlighting the results of our “Competition” in a variety of environments.
Insights from End Users trying … and failing … to achieve a permanent repair on polymers.
CompositesCentral Forum – “bonding dissimilar materials (HDPE to epoxy/fiberglass)”
Users unanimously note that HDPE is notoriously difficult to bond with epoxy and fiberglass, requiring special surface treatments and proprietary adhesives. One user writes: “epoxies will not work here”Boat Design Net – “Repairing HDPE”
The community agrees that welding or melting is effectively the only permanent repair method. Fiberglass and epoxy are ruled out because “virtually nothing sticks to [wax‑y] polymers”—including HDPE—making adhesive repairs unreliable boatdesign.net.FiberglassRV Forum – “fixed‑my‑water‑tank‑with‑fiberglass”
One enthusiast concludes bluntly:
“If the tank is HDPE or polyethylene of any kind the repair is doomed to fail … fiberglass forms chemical and mechanical bonds only to similar phenolic resins, not plastics.” en.wikipedia.org+13fiberglassrv.com+13mig-welding.co.uk+13SkidsteerForum – “Hydraulic reserve tank repair with fiberglass ?”
A member warns:
“Fiberglassing a plastic tank would make me nervous … vibration, expansion could make it just fall off.” skidsteerforum.comOldMiniBikes Forum – “Plastic Gas Tank Repair”
They clearly state:
“Epoxy, or any other adhesive is not going to work as a permanent repair.” gsctanks.com+3oldminibikes.com+3mig-welding.co.uk+3goodsamesp.com+5en.wikipedia.org+5resinlibrary.com+5Practical Sailor (“Repairing Plastic Tanks”)
A test comparing various repair methods found that fiberglass/epoxy kits failed under flex, promptly detaching after bending—although polyurethane-based options like G‑Flex had somewhat better results. The study concludes that welding plastic is still the most reliable repair method practical-sailor.com+1fiberglassrv.com+1.
Any type of pipe, any size of pipe
Tech Wraps™ can be engineered and applied to pipes of virtually any diameter. Once properly installed, their strength, durability, and resistance to demanding operating conditions are expected to substantially outperform conventional field-repair systems.
Testing conducted on a 78-inch-diameter HDPE pipe demonstrated the potential of the Tech-Patch Repair System™. The repair used only two layers of standard Tech Patches—not the heavier-duty Tech Wraps—yet withstood 1,800 psi for more than 100 hours at 20°C. Based on these results, we believe a properly engineered Tech Wrap repair can restore the pipe’s structural integrity and provide a service life that significantly exceeds conventional repair expectations.
Municipalities and Industries are Losing Billions!
Municipalities and industries are wasting billions of dollars on two costly options trying to achieve permanent repair of pipes and tanks: first, attempting to repair damaged tanks and pipes with conventional fiberglass-epoxy-based systems, or, alternatively, replacing the assets entirely. Too often, the first option provides only a temporary fix, while the second requires major capital expenditures, extended downtime, excavation, and disruption.
With budgets already in crisis and infrastructure-maintenance backlogs continuing to grow, repeating the same repair-and-replace cycle is no longer sustainable. Organizations need a stronger, faster, and more cost-effective way to restore damaged infrastructure, extend its service life, and avoid unnecessary replacement. With Municipalities, it’s more than a need.
How the numbers were calculated
Worldwide
A commercial market study estimates the 2025 pipeline-rehabilitation market at $32.8 billion, growing at 6.8% annually. It covers water, wastewater, oil and gas, and industrial pipelines. The market study was: “DataIntelo pipeline-rehabilitation study” https://dataintelo.com/report/pipeline-rehabilitation-market?utm_source=chatgpt.com
- 2026 pipe rehabilitation:
$32.8B × 1.068 = $35.03B - 2026 tank repair: $1.19B
- Total 2026 TAM: $36.22B
- 2036 pipes:
$32.8B × 1.068¹¹ = $67.63B - 2036 tank repair: $1.96B
- Total 2036 TAM: $69.59B
The tank component uses the reported repair-services segment—$1.076 billion in 2024 and $1.862 billion projected for 2035—not the entire tank cleaning, inspection and maintenance market. WiseGuyReports tank-maintenance study
United States
Two published pipe-rehabilitation estimates were triangulated:
- U.S. sewer and pipeline rehabilitation: $18.4 billion in 2025. IBISWorld
- North American pipeline rehabilitation: $12.4 billion in 2025; 90% was allocated to the United States as a modeling assumption.
The midpoint produces a $14.78 billion 2025 pipe estimate. After a 2% bridge to 2026 and approximately $326 million for tank repair:
- 2026 TAM: $15.4B
- 2036 TAM: $22.9B
I used 4% annual pipe-market growth for the central forecast. This is deliberately below the 7.1% North American forecast because another source anticipates near-term weakness. The large underlying need is supported by EPA estimates of $625 billion for drinking-water infrastructure and $151.1 billion for wastewater conveyance repair and new systems over 20 years. EPA drinking-water assessment, EPA Clean Watersheds survey
India
India required a modeled approach because no reliable, comprehensive India-only repair-market total was available.
The World Bank estimates $840 billion of Indian urban-infrastructure investment through 2036, averaging roughly $55 billion annually. Approximately $450 billion relates to basic municipal services. World Bank report
Central model:
- Basic municipal services: $450B ÷ 15 years = $30B annually
- Water, sewer and drainage allocation:
$30B × 30% = $9B - Repair and rehabilitation allocation:
$9B × 8% = $720M - Industrial, energy and commercial uplift:
$720M × 35% = $252M - Total 2026 TAM: $972M, rounded to $1.0B
- 2036 at 8.5% annual growth: $2.2B
The India allocation percentages are explicit modeling assumptions, which is why India carries more uncertainty than the U.S. and worldwide estimates.
These figures exclude new construction, full pipe or tank replacement, and ordinary tank cleaning and inspection. Consequently, the total economic problem—and the potential savings from avoiding replacement—is substantially larger than this repair-only TAM.
The “Good News” for you – the Tech Patch Repair System is a permanent repair system for poly tanks and pipes which also works on metal pipes and tanks.
Applied correctly, the Tech Patch Repair System permanently repair HPDE pipes and tanks, steel pipes, copper pipes, Two points to make. First, the application process is not difficult and, secondly, energy, energy from trauma, energy from shock stress, energy from applied stress will cause a Tech Patch or Tech Wrap to fail. What will not cause failure is the weather, chemicals, fuels (gasoline, diesel), aging, etc. Finally, neither Tech-Patches or Tech Wraps age.
If Tech-Patches are so good, why aren’t they available? And why haven’t we heard about them?
If TPRS™ and Tech-Patches Are So Good, Why Aren’t They Available?
They are becoming available—but not yet through the broad retail and industrial distribution channels people normally expect. TPRS™ is not simply another adhesive or epoxy product. It is an engineered repair system that requires the correct materials, preparation, application process, and—in demanding industrial applications—trained technicians. Before expanding availability, Tech-Bond concentrated on developing the system, refining the procedures, validating its performance, and establishing the training needed to produce consistent results.
Tech-Patches are now being introduced as a more accessible version of this technology for common pipe and tank repairs. They will allow homeowners, plumbers, maintenance personnel, contractors, municipalities, and industrial operators to complete repairs that previously required wrapping, welding, fiberglass and epoxy systems, or complete replacement.
Why Haven’t We Heard About Them?
Because technological performance and market visibility are two different achievements. Tech-Bond is a small technology company that invested its resources in research, testing, validation, and product development—not national advertising and mass distribution. Meanwhile, the repair industry has continued to operate around conventional adhesives, epoxies, mechanical connections, and replacement.
There is another reason: the market has been taught for decades that polymers—especially materials such as polyethylene and PTFE—cannot be reliably bonded. A technology that challenges such a deeply established belief must do more than make claims. It must produce evidence.
That evidence now exists. Independent testing and field applications have demonstrated exceptional bond integrity, pressure resistance, environmental durability, and, in some tests, failure of the reinforced patch material before failure of the TPRS bonded interface. Tech-Bond has spent years establishing what the technology can do. The next phase is making it available, training people to use it correctly, and bringing it to the markets that need it.
You have not heard much about TPRS and Tech-Patches because the technology has been undergoing development and validation. That is now changing.
Plastic Gas Tank Repair
The video below applies to all types and styles of plastic gas tanks and includes HDPE tanks, polypropylene tanks and the extremely rare nylon gas tanks. A-Patches actually work on metal tanks in additon to plastic tanks.
Why Patches Fail
Proudly, our A-Patches and Tech Wraps are effective with a 99% plus success rate. Of course, there have been situations where A-Patches have failed. Usually, these failures have been because of application errors. In virtually every case, the second attempt was successful. There are three primary reasons why an A-Patch fails. These are listed below.
- A fold or crease in the A-Patch. This gives fuels a way out.
- Too much Bonding Agent was left between the tank and the A-Patch/ Wrap. Molecular bonding requires surface-to-surface contact and with that bonding the Bonding Agent become part of the structure.
- The surface does not get warm enough. Therefore, the required exothermic chemical reaction does not start.
Engagement – Experience – Execution
At Tech-Bond, Engagement is not just a word—it’s a philosophy, a mindset, and our preferred way of operating. Since 2016, we have been actively implementing and refining both the Polymer Bonding Process and the Tech Patch Repair System (TPRS™), and we are still learning every day. We learn through application, we learn through testing, and—most importantly—we learn from our clients. Their challenges fuel our innovation.
The Tech Patch Repair System, our first global solution, was born from a real-world request: to find a way to stop active leaks in gasoline and diesel tankers on the highway. While TPRS ultimately proved unsuitable for that exact scenario, the journey led us to an entirely new class of solutions—permanent repairs for HDPE gas tanks, HDPE water tanks and pipes, metal pipes, and more. These field-tested capabilities emerged from hands-on problem solving and direct collaboration.
Since our founding, Tech-Bond has also partnered with a number of small, entrepreneurial companies to help bring new products to market—solutions made possible through our technology, experience, and shared vision for innovation. Many of these products are already commercially available, and we’re eager to continue collaborating with forward-thinking teams that value creativity, performance, and long-term partnership. – Ex
