Alright guys, here's the deal. My dad called me this morning with some inquiry about GeoTex. He got called to go do a retaing wall bid, wall height is 10 feet tall and he has been provided the engineering specs, so he doesn't need to find an engineer, it's already been done. He said it's fairly thorough, except for where to tie the GeoTex to the blocks. The engineering calls for a certain type of block, it is a batter type block so it's not vertically pinned, which I'm curious about. I can see how it would be simple to attach the tex between blocks using the pin system, just run a loop of the material through the pin, drop a block on top and keep on going. Second question pertains to attaching the other end of the material to the slope. I haven't personally seen the engineering plans, so I'm not 100% sure if it says anything in there about that. I didn't really ask my dad and I'm not sure if he's read all the way through the 15 pages of material, he just got the plans yesterday and has briefly looked over them. He does say that the tex is required every 3 tiers of blocks with this design and the drainage system is very well explained. I know this isn't rocket science, but having no experience with GeoTex poses a few questions to start with. So my question is, are there multiple methods for securing the GeoTex to the slope? And does anyone have experience with batter type blocks using the tex? Like I said, seems simple with vertical stack blocks and pins running vertically, but I'm not sure about the batter style and where to secure the tex to them.
