Liu Geotech Report 12.12.13.pdfBedrock Group,Inc.
At the request of Aziz, I crime onsite to meet with him to discuss disposal of water in footing drain and construction
of spreader pipe dispersion systems for roof runoff. The project site is underlain by gravel sand soil of high .
permeability. Therefore, water collected into footing drain of the residence will be inconsequential if any at all.
Therefore, it won't require a large system to dispose water in footing drain. I inform Aziz that a 2 feet x 2 feet x 3
feet deep drywell pit off each corner of the house will be sufficient to handle water in footing drain. The drywell
should be filled with clean 314 to 1-112 inch washed gravel to within about 10 to 12 inches of the top. The gravel fill
should be covered with a layer of non -woven filter fabric and the remainder drywells then filled with onsite clean sandy
. .........
soil. The footing drain should be tightlined to drain water into the gravel fill of the drywells.
Aziz covers the storm inlet at the end of the paved joint -use driveway with a filter sock. -.
