Streamlining operations for same-day release and shortening construction periods! Solving issues such as wanting to increase the water flow cross-section!

The "W2R Method" is a construction technique that involves cutting unnecessary parts of existing drainage ditches from the inside using a specialized cutter called the "W2R Cutter," and then installing a precast concrete cover known as the "W2R Drain Cover" to renew the ditch. Noise from chiseling with an electric hammer and dust generated during chiseling can negatively impact nearby residents and users. This method addresses those issues and contributes to CO2 reduction by alleviating traffic congestion through rapid construction without affecting existing sidewalks or private land. 【Features】 ■ The W2R Cutter can cut from the inside without damaging the drainage ditch. ■ The W2R Drain Cover has excellent workability. ■ The W2R Drain Cover excels in walkability and drainage performance. ■ It has minimal impact on existing sidewalks, private land, and surrounding residents, showing consideration for the environment. ■ The cutting surface of the W2R Cutter is smooth, and by installing the Pca cover after cutting, it enhances workability and shortens the construction period. *For more details, please refer to the PDF materials or feel free to contact us.
