How UV-GRP Lining Can Enhance Drainage Systems
Drainage systems are the unsung heroes of our infrastructure, silently channeling away water to prevent flooding and ensure public health. But traditional repair methods for damaged or aging drains often involve extensive excavation, disrupting daily life and causing environmental disturbances. Thankfully, innovative trenchless technologies like ultraviolet light-cured, glass-reinforced pipe (UV GRP) liners offer a game-changing solution for enhancing drainage systems with minimal disruption and long-lasting benefits.
Alphaliner UV-GRP is proving itself to be one of the most advantageous choices by DOTs and agencies responsible for drainage systems due to:
- Structural reinforcement of the host pipe
- Smooth surface that improves overall drainage
- Corrosion resistance to harsh chemicals or environmental factors
- Leak-proof watertight sealing for enhanced protection
Alphaliner is a seamless, glass-reinforced and spirally wound liner that can be tailored to fit the exact specifications of storm drainage structures or sanitary pipes. It is available in diameters ranging from 6” to 72” and lengths in excess of 1,200 feet and can accommodate a variety of pipe shapes and host structure materials.
Case In Point
Alphaliner UV-GRP has been utilized worldwide for the rehabilitation of storm drainage assets and has been the answer to many challenging projects where traditional open-cut or felt/resin CIPP would not be feasible or advisable. One such project utilizing Alphaliner in Baltimore County is a prime example.
A rehabilitation was needed for 96 linear feet of twin 72” diameter corrugated metal pipes that passed under a county road that accesses an apartment community’s main office, and beneath the swimming pool amenity for the entire community. The single point of access to the main offices ruled out the traditional dig-and-replace method as a viable option, due to potential life safety impact with limited access by fire and emergency medical services. Open cut was also ruled out because an existing playground directly adjacent to this site presented dangers to children there. Unfortunately, this latter concern also ruled out several potential trenchless methods.
Alphaliner UV-GRP lining was determined as the best solution. Within 48 hours of crews arriving on-site, the pipes were rehabilitated and returned to service without any trenches or open-cut excavation. Possible structural concerns, now and in the future, have been eliminated. Due to the success of the project with such limited disruption to the community, the local municipality has been utilizing UV GRP lining on a number of problematic lines throughout other parts of the county, as well as the continued use in corrections to stormwater assets and failing outflow lines.
As can be seen from this example, the adaptability of UV GRP liners allows them to be used in pipes of various sizes and materials, making them a truly comprehensive solution for drainage system enhancement. Their trenchless installation minimizes any disruption and environmental impact, establishing them as a sustainable choice for modern infrastructure. With their cost-effectiveness and long-term value proposition, Alphaliner UV-GRP liners are poised to become a cornerstone technology for building and maintaining drainage systems for years to come.
