New Slope Stabilization Method Prevents Slope Failure Without Clearing Trees

A new non-frame slope stabilization method developed by Nippon Steel & Sumikin Metal Products Co., a Japanese construction material company, has been growing in popularity amid serious landslide disasters caused by earthquakes, typhoons, and heavy rains across Japan. While conventional stabilization methods cut down trees, correct ground irregularities, and then cover the ground with concrete, the new method can stabilize and strengthen slopes without disturbing the terrain or existing forest vegetation, preserving its green cover.

The new non-frame method takes advantage of the natural ability of trees and vegetation to stabilize slopes. Installing reinforcement materials, grout, stiffeners and rope-wire further improves slope stability based on the interacting effect of reinforcement and ground. Because this method does not require tree removal, the natural landscape and environment remain intact after stabilization work. The method also generates no surplus soil or felled trees to be carried off site, which makes it applicable in locations where heavy machinery is difficult to operate.

The non-frame method won the Good Design/Sustainable Design Prize (Minister of Economy and Trade Award) and Minister of Land and Transportation Award (Eco Service category) at the 2011 Good Design Award and 8th Eco Products Awards, respectively.
