Maru Liner Method MARUNAKA

The Maru Liner Method is a technique in which a core material containing epoxy resin is inserted into a drainage pipe and lined along the inner wall, thereby forming a new pipe inside an aged drainage pipe. The Maru Liner Method is a proprietary patented technology developed by Marunaka. Unlike traditional methods, there is no need to replace deteriorated drainage pipes, which allows for shorter construction periods, space-saving, low noise, environmentally conscious practices that minimize waste, and unnecessary cost reductions. Additionally, by eliminating the 'pipe joints,' which are a major cause of deterioration, the drainage pipes can be regenerated to have high durability and excellent drainage performance. The method boasts durability of over 30 years and is backed by a reliable 20-year warranty.
