[Company strength]
Mini ram sounding testing (dynamic penetration testing) is a fast, inexpensive method. It can be used for accurately checking pile length in pile foundation ground or confirmation surveys where Swedish weight sounding continues at a high level. This test is particularly powerful when checking the bearing layer but has a disadvantage in layer judgment. This is why we developed an eco-ram to enable layer judgment by a dynamic penetration test capable of sampling. Our company was the first in Japan to register with Dutch drilling company SonicSampDrill (SSD) as a dedicated operator. Their products enable sampling of soft ground, sold bedrock, and other kinds of ground that used to be difficult for conventional boring machines.


[Representative's message]
High-vibration-type Dutch drilling machines (SSD) can bore holes quickly and safely even in layers that are difficult for conventional boring machines or where there are obstacles underground.
