can someone clarify a few thngs for me. I will not attempt a project before I am convinced that I know how to do it inside and out. For a wall, i have 3 questions. 1) The drawings in the tech manual for the stone we use says to layers of geotextile to tie the wall back into the soil. What is the difference between goetex and grid. Also, how is it ancored to the block. 2) When backfilling the wall. Lets say it calls for 48 inch lengths of geotex as ties, is that whole area done with 3/4 clean and wrapped in geotex, or are the horizontal layers of geotex sandwiched with soil. 3) In the drawings, it show the 4 inch perf drain in the compacted 0-3/4 base below the footing, with the compacted base extending to the back of the backfill zone at a 2% slop. Do you guy put your drains in the 0-3/4 or in the 3/4 clean?? Just want to get this clear befor I build any wall. I have done several patios, but no walls.
