Sewer Trench Mine Void
Sewer Trench Mine Void
(OP)
I have a sewer project in the design phase and part of my due diligence, I came across potential areas of mining in the area where the top of the mine voids could be approximately 6ft below ground. The sewer design is 8'-10' depth due to slope and stream crossing depths downslope. We will be doing some drilling to confirm the seam roof. My question is, I'd like to make sure I quantify (by line item) on the bids for filling in voids in the trench, most likely by C.Y. or tonnage. To keep contractors in line and decrease change order issues. I can't imagine having to grout in these voids. Is there some sort of standard flyash/grout material that solidifies that is cheaper?
