Recently, we see more manifold demands for engineering method as there have been more diversified construction sites which are changing in a course of time.Many of constructions must be done at steep slope, natural slope along mountains or in small space. The Lower Drill Method was developed as the most practical and efficient method to execute high quality piles under such difficult conditions.
Only one unit can do both screw and down-the-hole-hammer excavations.
By utilizing its advantage of being compact and low gravity, it made us enable to execute the safe, sure and speedy work which will meet the demands of the age. 
The Lower Drill Method will realize any kind of pile work in any kind of ground.
