Product Q&A
Q:How does the concentric block system work in bridge foundation drilling?
A:
The blocks expand during drilling to advance the casing through riverbed gravel, and retract when pulling back for retrieval.
Q:What is the advantage of this system over eccentric for bridge piers?
A:
Concentric systems provide better hole straightness in soft ground, essential for vertical bridge pier foundations.
Q:What formations is this bridge foundation bit best suited for?
A:
This bit delivers optimal performance in alluvial soils, riverbed gravel, soft ground, overburden, and sandy clay.
