Kenner, Louisiana Patent of the Year – 2024/2025
BLD Services LLC has been awarded the 2024/2025 Patent of the Year for its innovative pipe lining system. Their invention, detailed in U.S. Patent No. 11933445, titled ‘Pipe lining systems and methods of use’, introduces a cured-in-place pipe (CIPP) lateral liner assembly designed to enhance the efficiency and reliability of pipeline repairs.
The patented system features a CIPP lateral liner inserted into a bladder, forming a liner assembly that can be deployed within existing pipelines. A key component is a specially designed backing ring that includes both bonded and unbonded portions. This configuration creates a pocket between the unbonded portion and the main line liner, facilitating improved adhesion and sealing during the curing process.
This advancement addresses common challenges in pipeline rehabilitation by providing a more secure and durable lining solution. The design ensures better conformity to the host pipe’s interior, reducing the likelihood of leaks and structural weaknesses. Such improvements are critical for maintaining the integrity of water and sewer systems, especially in aging infrastructure.
Based in Kenner, Louisiana, BLD Services, LLC is recognized as the world’s largest CIPP lateral lining company, with over 100,000 successful installations. Their latest patent exemplifies the company’s commitment to advancing trenchless rehabilitation technologies, offering municipalities and utilities more effective solutions for pipeline maintenance and repair.
