Backfilling with Angular Drainage Rock

so two things are happening we are currently experiencing extreme block shortages to the point where we are ordering our materials one plus month in advance to make sure that they're ready by the time we're starting the job so we've got to be very accurate with our material count when we go in to order it so if you guys are looking at doing your own project in your backyard or doing something for somebody else make sure before you start it that you have the actual right materials on hand the second thing that i'm noticing is is not just something that is a block related i went to one of the big box stores the other day to order concrete just some bags of concrete the entire store had no concrete in it at all 5 000 bags of concrete is what they typically have on hand they had none available that i could walk out the store with and they said they didn't know when the next batch was going to come in do not use p rock if the contractor you hire brings p rock out to your job site you're in trouble so what i'm talking about is the drainage material that we use behind our retaining walls is always the exact same thing it's called three-quarter clear sewer rock that's the technical term for it and basically what it is it's a very very angular stone that we specifically pick out for its size and shape that three-quarter inch rock angular in nature locks together as soon as you lay it in place so any way that it falls is going to lock and that's going to resist movement the reason you don't want p rock is because that p rock with that circular tiny stones if you get enough water flowing through it it can roll and move and if you have rock rolling and moving behind your retaining wall it can mitigate the fines out of the soil loosen the soil up create hydrostatic hot spots which is basically a super fancy word to say channels behind your wall and anytime you get a channel behind your wall you've now created the path of least resistance for water to follow and that can create a wall failure and you don't want that to happen so do not allow any contractor to use p-rock make sure you get the right drainage material because that's the best way to ensure that you get the best product with the longest lasting results out there so pick the right rock right out of the gate and the rock that's in the drainage zone is the exact same material that we use for the base we don't change that up in any way shape or form [Music] we're going a little bit wider on the rock than we…
