1100 SLIP-LINING SANITARY SEWERS 1100.1 DESCRIPTION: This item shall consist of slip-lining sanitary sewer pipe, which is accomplished by pulling or pushing liner pipe into existing sewers by. large void spaces and is loosely compacted. The moisture content at which a soil can be compacted to its maximum dry density with the least amount of comparative effort is called the optimum moisture content. Lime is used with soil to add strength to the mixture, to raise the pH of the mixture, to assist in drying out soils, and to reduce soil plasticity. 3) 104 in.
