Strong in construction on slopes where heavy machinery cannot be used! Driving piles into stable ground to resist sliding forces.

We perform 450mm diameter drilling using a down-the-hole hammer with a spindle-type machine. We excel in construction on slopes where heavy machinery cannot be used by utilizing monorails or our own unique temporary structures. In pile work, we drive piles deep into stable ground below the sliding surface to resist the forces trying to cause sliding, and in fencing work, we construct rockfall protection fences, avalanche protection fences, and landslide protection fences composed of posts with high rigidity and excellent displacement performance, as well as energy-absorbing buffer fittings. 【Construction Examples】 ■ Landslide Countermeasure Work - Pile Work ■ Slope Protection Work - Fencing Work *For more details, please refer to the related links or feel free to contact us.
