I am just throwing out ideas. <br /> Any way you choose to accomplish the goal will be fine with me. <br /> I will be in the field if you need to talk to me my cell number is(209) 601-0429. <br /> Johnny Yoakum <br /> Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> From: Ryan Woodward [mailto:rxan@woodwarddrilling.com] <br /> Sent: Tuesday, August 06, 2013 4:57 PM <br /> To: John Yoakum [EH] <br /> Subject: Pressure Grout Requirements for SJCEH <br /> Good Afternoon John, <br /> We are in the process of building a special tool designed for creating the mushroom caps for the 2" pressure grouted <br /> wells. <br /> To confirm, in San Joaquin County,you require/ request a mushroom cap that is 12" larger than the diameter of the tool <br /> originally used to drill the well, correct? <br /> Therefore, if a 2" well was drilled with an 8" auger, we need to create a mushroom cap that is 20" diameter x 3' bgs <br /> around the top of the well. <br /> I just want to make sure before we spend time& money building the tool. <br /> Your response is greatly appreciated,Thank you! <br /> Ryan Woodward <br /> Procurement Manager <br /> Woodward Drilling Co. , Inc <br /> i <br />
