Vertical Drilling for Grouting

[struct4me]

WE are planning to do a deep drilling by down-to-bottom (symmetrix) method from ground to almost 150 m below ground in mostly rock to grout the shaft area in concentric way of drilling holes (120-200 mm diameter) and thereafter do the cement/chemical grouting. This is to be done to arrest the water leaking from the vertical surge shaft for a hydro power station.
Can any one help me in estimating the price rate (i.e. price per m of drilling) analysis for the drilling works with multi stage option using packers.
Your help will be much appreciated.
Thanks & Regards

Bid on a volume of grout and unit price of drilling, etc.basis. Otherwise you may well find it was a big mistake.

I would ask a grouting contractor in your area...unless you are lucky and there is a forum member who works for a grouting contractor.
