Micropiling of I-Section Piles - Too many refusals
Micropiling of I-Section Piles - Too many refusals
(OP)
Hello all,
We're having no luck ramming our ca. 150mm I-section piles into the ground.
As per the Geotech, the ground is very hard with lots of rocks of up to dia. 300mm.
What to do? We've tried pre-drilling with an auger but it seems this method won't achieve the desired results.
What else can we try?
Thanks in advance.
Regards,
Simon

Micropiles are made to go into bedrock. You drill right into it and bond to the sides. I've gone into very dense rock with them before and gotten hundreds of tons of capacity. No need to ram/drive anything.
You may want to contact a micropile contractor for a solution. Hayward Baker is a good one to talk to.
