Grout to ground bond stresses in Green Bay, WI
Grout to ground bond stresses in Green Bay, WI
(OP)
Hello all,
I have a question as to where I can find some desktop information about grout to bind stresses for micro pile foundations in Green Bay. A geotechnical investigation report has been prepared for this project but the data suggests extremely low bond stresses. I would like to verify this information if at all possible. After a cursory Internet search, I have not been able to find much. Any help with any type of information would be greatly appreciated.
Thanks

Thanks again for the quick response.

Will the bonded length be in soil or rock? What type soil or rock? Pressure grouting does not work in impermeable soil or rock.
FHWA has a publication on micropiles. PennDOT has their Design Manual DM-4 on line. Its Appendix O addresses micropiles.
As JedClampett said, PTI has recommended range of ultimate bond values for various soils and rock. If you are designing any type of ground anchors or micropiles, you should have the PTI and FHWA references and manuals.

I am the micropile drilling contractor but we are not local to Green Bay. We anticipate bonding in clay soils. Unconfined compressive strength at our bonding depth is about 5 tsf. I am really just looking for some information that may justify me using higher than 5 psi.

Doug, I am sure it has been said to you many times before, but with a first name of "dug" and a last name of "hole" you were destined to be a geotech engineer...or a grave digger.
Sorry for the hijack...carry on...
