Geogrid Layering and Efficiency

top of that then one more on top of that and then caps now one of the things that always looks off that i need to explain to you is that grid that you just seen there that looked all higgledy-piggledy the walls here the grid is flopped down there's rock under here and what we learned when we were doing all commercial work was to speed up the building process what we don't do is lay one course of block down then backfill it lay one course a block down then where's the block going back that's just too tedious and time consuming to keep switching gears back and forth but we do do is i did say doo doo we put four courses of block up and the reason we put four courses of block up is because that is where your grid spacing is always in a retaining wall so that we always have a one layer of geo grid that we're backfilling either up to or over the top of and what we do with that geo grid is if we're back filling up to it is we flip it up over the face of the wall we get everything nice and level to where that grid start stops and we slap that down onto the dirt and then we can keep back filling up to the back of that top block but by being able to strategically and carefully put four courses up we also realized that we were able to speed up the building process which is not as critical in a residential retaining wall but it's hyper critical in a commercial retaining wall and so a lot of the tips and tricks and techniques that we use on that you see in these videos were actually pulled off from when we were building massive commercial sites and we had to keep up with the joneses basically to be able to land the bits
