Small-Diameter Propulsion Construction "Grundram Method"

We will propel a steel casing pipe using a pneumatic impact propulsion device called a Grundram!

The "Grundram Method" is a construction technique for small-diameter thrusting work that uses the pneumatic impact thrusting machine Grundram to advance steel casing pipes. Since the steel pipes cut through the ground, they do not damage the surrounding soil and have a wide adaptability to soil types, particularly suitable for gravel and cobble layers. Please feel free to contact us if you have any inquiries. 【Features】 ■ No need for support walls, making it easy to combine with open-cut methods (can be advanced from simple soil retention) ■ Wide applicability to various ground conditions, particularly strong in gravel and cobble soils ■ The open-ended design of the steel pipe tip allows for compatibility with other methods *For more details, please feel free to contact us.
