Grantline boring permit <br /> it's NOT a matter of adherence to our Ordinance. it's a matter of consistency. <br /> either material is fine, assuming they are per manufacturer's intended use, i.e. NOT using <br /> drilling mud bentonite to seal/grout a hole . <br /> It's just that you claimed TWO different APPROVABLE methods (work plan said <br /> BENTONITE, not bentonite cement mix, and the permit listed a MIX of cement AND <br /> 5% bentonite. I need to know which ONE you will be using... as in just BENTONITE or <br /> just cement bentonite mix <br /> so please, choose one and advise me. It's even OK to use both, just match work plan <br /> and application by specifying where each is to be used. <br /> then, either revise the work plan (page 3 center paragraph and page 4, top paragraph) to <br /> say "Portland cement with 5% bentonite" or stay with BENTONITE as the work plan says <br /> now and I'll revise the permit application by removing "portland cement with 5% <br /> bentonite" and adding BENTONITE (chips, pellets, or slurry). <br /> this isn't that difficult. I just want the permit application to match the work plan/vice versa. <br /> mike. <br /> From: Guthrie, Kristin [mailto:Kristin.Guthrie@parsons.com] <br /> Sent: Friday, February 11, 20119:56 AM <br /> To: Mike Infurna [EH] <br /> Cc: Elizabeth Creek <br /> Subject: RE: 502 E. Grantline boring permit <br /> Mike, <br /> Below are the San Joaquin grout requirements that I found. Is Elizabeth's response on the <br /> application not in adherence to the San Joaquin County Requirements? It looks to me that they <br /> are saying the same thing just a little differently. Please let us know if you would like us to change <br /> the percentages on the permit to match the County's requirements or if you would like me to <br /> update the work so its wording exactly matches the permit application. <br /> 4.7.3. Sealing Material: <br /> Neat Cement - 1 bag (94 lbs.) Portland Cement to 5 to 10 gallons of potable water. <br /> Cement Grout- Not more than two (2) parts by weight of sand and one (1) part by <br /> weight of cement (per bag of cement)to 5 to 7 gallons of potable water. <br /> Bentonite-sealing materials and their uses shall be in accordance with the <br /> manufacturers specifications or as approved by the Director. <br /> Quick setting type cement, retardants to setting, Bentonite, or other additives, may be <br /> used not to exceed 5% of the volume. Hydrated lime may be used up to 10% of the <br /> volume. <br /> 2/15/2011 <br />
