The Neplus Method National Association is an organization that promotes the expansion of the "Neplus Method" for the repair of the upper part of drainage ditches, provides technical support, manufactures and supplies products, and offers technical assistance to construction partners. The Neplus Method involves removing only the damaged upper part of the drainage ditch with a specialized cutting machine and installing new repair products to renew the ditch. The construction period is quick, allowing for immediate traffic reopening if about 10 meters are completed in a day. Additionally, it can be easily implemented even in ditches close to structures or underground installations without the need for excavation. We have handled numerous drainage repair projects to date. If you have any issues with drainage work, please feel free to contact us.
