Im looking for some basic construction info on retaining wall's. First. None of the info I find on line show's any use of seperation fabric, including the versa-lok site. I dont understand how this is considered common practice with walkways/patios and not mentioned anywhere with wall construction. Do you use fabric for walls? 2nd, would doing a retaining wall "the old fashioned way" with simpler construction techniques today be considered "hacking"? There are 100 year old walls around that are backfilled with dirt, faces built a 10 degree slant's, etc. This seem's like it could be a good way to offer a cost effective method to shorter retaining walls as long a you dont try to sell it as "proper". Does anyone offer this? I found one rule stating, "base for stone walls should be half as wide as the height" 6 ft wall = 3 foot width base. with a min of 2 ft width for all short walls. Why does versa lok have dirt backfilling the first base layer instead of aggregate? do you specifically put drainage pipe in with stone walls? What is the standard for inward slope for a proper stone wall per ft of height? Too much all at once?
