PML Method: A manhole rehabilitation technology with low environmental impact and minimal work noise.
We will repair the sewage facilities using an anti-corrosive membrane made of factory-produced acid-resistant polyethylene material. Since it is a technology for installing secondary products, adjusting the construction schedule is easy.
An environmentally friendly polyethylene liner serves as a corrosion-resistant membrane. This technology produces less noise during work since it does not require large equipment. Additionally, it does not use harmful organic solvents, providing a healthy environment for workers. 【Applications】 ● Reconstruction and extension of the lifespan of aging or damaged manholes 【Features】 ● The factory-produced liner is processed into a complete single piece, ensuring very stable quality. ● Being a finished product, it can be safely stored until actual construction takes place. ● It can be postponed in case of adverse weather or if construction must be delayed. ● It has extremely high acid resistance against acids specific to wastewater environments generated by aerobic bacteria. ● Work can be carried out even during wastewater use by using special packers.

Company information
Since its establishment, our company has played a role in national construction, primarily focusing on the "ground improvement field" with our unique grouting method. Subsequently, in response to the changes in social infrastructure development, we have refined our technologies to adapt to the needs of the times and, at times, acquired new ones to expand our business scope. As a result, we have now established three main pillars: "ground improvement business," "slope disaster prevention business," and "pipeline business."
