This is an introduction to the "Soundproof Type" Neplus method suitable for noise prevention in side ditches.
The Neplus method "Soundproof Type" is suitable for locations where stores or residences are adjacent to drainage ditches and excavation cannot be performed, or where excavation cannot be done at parking lot entrances or retaining walls. By using the soundproof type, noise such as rattling sounds can be prevented. In conventional methods, the work takes 4 to 5 days, but the Neplus method can be completed in one day, making it safe to use even in stores, residences, and busy parking lots. 【Comparison with Conventional Methods】 ● Conventional Method Survey → Temporary Closure → Pavement Slab Crushing → Mechanical Excavation → Foundation Work → Drainage Ditch Installation → Pavement Restoration → Completion - Days: 4-5 days - Asphalt Waste: 0.30 m² - Excavated Soil Volume: 30.5 m² - Concrete Waste: 0.87 m² ● Neplus Method Survey → Cutting → Installation of Renovation Products → Backfilling Material → Installation of Cover Plate → Completion - Days: 1 day - Asphalt Waste: 0 m² - Excavated Soil Volume: 0 m² - Concrete Waste: 0.17 m² *For more details, please contact us or download the PDF materials for review.
