The TechPolymer Group of Companies presents a comprehensive solution for extending the service life and improving the reliability of water conveyance structures — reinforced concrete sections lined with a polymer anchor sheet during production. The technology, tested at federally significant facilities such as the R-255 “Siberia” highway, demonstrates significant advantages over traditional methods.
The problem requiring a solution
Intensive loads, exposure to aggressive environments and abrasive wear are the main factors leading to the rapid deterioration of conventional reinforced concrete pipes. This results in frequent, costly repairs and threatens the uninterrupted flow of traffic.
Factory quality
The solution lies in integrating a protective polymer layer into the structure during the manufacturing stage. Under factory conditions, the inner surface of the reinforced concrete section is cast integrally with a high-density polyethylene (HDPE) anchor sheet. A continuous waterproofing and anti-corrosion coating is formed.
Key technology benefits
-
Up to 82% reduction in operating costs: Calculations for the facility on the R-255 “Siberia” highway showed a reduction in total construction and operating costs over 24 years.
-
Maximum resistance to abrasive wear: According to the Darmstadt test, polyethylene (0.07 mm wear) is six times more resistant than concrete (0.40 mm).
-
Extended time between repairs: The structure does not require frequent intervention throughout its service life.
-
Fast installation: The use of ready-made lined sections makes it possible to assemble water conveyance pipes at the site within a short time.
Expert recognition and practical implementation
The solution for using lined reinforced concrete products in water conveyance pipes was included in the design documentation and received a positive conclusion from Russia’s Glavgosekspertiza. The successful operation of the structures during the 2024 spring flood confirmed the calculated reliability and flow-capacity parameters.
“Construction using prefabricated lined blocks combines the high factory quality of reinforced concrete products with a ready-made protective coating, fundamentally changing the life-cycle economics of infrastructure facilities,” experts from the TechPolymer Group of Companies note.
The TechPolymer Group of Companies has many years of experience in protecting concrete structures and is ready to cooperate on implementing modern solutions at your facilities.
