Section V-507 - Plugging and Fill Materials
Universal Citation: LA Admin Code V-507
Current through Register Vol. 50, No. 9, September 20, 2024
A. Requirements or criteria for plugging or sealing material and fill material to be used in accordance with these standards are as follows.
1. Plugging or Sealing Materials
a. It is recognized that no material is
completely impervious, however, experience and test show that neat cement or
cement slurry has a low enough permeability to be preferred for use when
plugging and/or sealing is required. Neat cement or slurry is a mixture
consisting of one bag of cement to five to ten gallons of water. Under certain
conditions, other materials may be added to accelerate or retard the time of
setting and to provide extra bulk. If a gel or bentonite is used, the quantity
added should generally vary between one and four percent. Cement grout or
concrete grout may be used in place of neat cement or cement slurry if the
change is approved by the Louisiana Department of Public Works or the
commission. Following are definitions of cement grout and concrete
grout.
Cement Grout-a mixture consisting of not more than two parts of sand to one bag of cement (94 lbs.) and five to ten gallons of water.
Concrete Grout-a mixture consisting of cement, sand and gravel, and water in the proportion of one bag of cement (94 lbs.) to an equal volume of dry sand and gravel, and five to ten gallons of water.
b. Unless specified otherwise,
plugging material shall be placed in one continuous operation by the
circulation or pump method. The grout or slurry shall not be poured or dropped
through the water.
2.
Fill Materials. The following materials of low permeability (less than.001
millidarcies) are suitable for use as a filler when permitted by these
standards: silt, sand and clay mixture, native soil, mud-laden fluid weighing
not less than 9 pounds per gallon, a well-proportioned mixture of these
materials or with those materials mentioned in Paragraph 1-1.b above. Fill
material shall be free of foreign and organic additive material.
