Roth Quality Homes JN 90016 January 25 , 1990 Page 9 rock wrapped in non-woven geotextile filter fabric (Mirafi 140N, Supac 4NP, or similar material ) . At the highest point, the perforated pipe invert should be at least as low as the bottom o.f the footing and it should be sloped for drai. age . All roof and surface water drains must be kept separate :rom the foundation drain system. A typical drain detail is attached to this report as Plate 5 . No groundwater was observed during our field work. However , seepage into site excavations is possible, and if encountered should be drained away from the site by use of drainage ditches , perforated pipe or French drains , or by pumRing from sumps interconnected by shallow connector trenches at the bottom of the excavation. The site should be graded so that surface water is directed of.f the site and away from the tops of slopes . Water should not be allowed to stand in any area where foundations, slabs , or pavements are to be constructed. Einal site grading in areas adjacent to the house �hould be sloped at least two ( 2 ) percent away from the building, except where the area is paved. GENERAL EARTHWORK AND STRUCTURAL FIL we recommend that the building and pavement areas be stripped and cleared of all surface veretation, all organic matter , and other deleterious material . Structural fill is defined as any fill placed under the building, behind permanent retaining and foundation walls , or in other areas where the underlying soils need to support loads . Geotech Consultants, inc. should observe site conditions durir.� and after excavation prior to placement of any structural fill . All structural fill should be placed in horizontal lifts with a moisture content at or near the optimum moisture content . The optimum moisture content is that moisture content which results in the greatest compacted dry density. The moisture content of fill soils is very important and must be closely controlled during the filling and compaction process. . The allowable thickness of the fill lift will depend on the material type, compaction equipment and the number of passes made to compact the lift. In no case should the lifts exceed GEOTECH CONSULTANTS , INC.
