Perforated or slotted rigid PVC pipe should be tight jointed and laid with perforations or slots down, <br /> and with positive gradient toward discharge location(s). The pipe should be placed at or slightly <br /> above the elevation of the bottom of the footing. Do not replace rigid PVC pipe with flexible <br /> corrugated plastic pipe. <br /> 2.) Do not connect other drainage lines to the footing drain lines. Drain line cleanouts should be <br /> installed at appropriate locations to allow inspection and maintenance of the lines after construction. <br /> 3.) If the backfill will support sidewalks, driveways, patios, or other structures, it should be compacted <br /> to at least 90%of its maximum dry density based on the Modified Proctor test method,except that <br /> the top 12 inches of the backfill should be compacted to at least 95%of the maximum dry density. <br /> 4.) The geotextile filter fabric should be placed around the drain rock as shown, and not wrapped <br /> directly around the pipe. <br /> TYPICAL FOOTING DRAIN <br /> GEO Group Northwest, Inc.
