Repair Small Sunken Area with Hand Compaction

[Music] so Todd found something kind of neat this whole area here it was sinking so we're you know gonna raise it up like the rest of it he pulled these first two bricks out and there is nothing under two right about here so these whole two rows are just being supported by the friction fit of all the bricks book and that's it good probably good four inches more from the top of the block and Sprite about six to the bottom here in the front so if you have a patio that butts right up to a retaining wall this is very common because you're not actually supposed to compact right up behind a retaining wall you're supposed to actually leave about three feet and this becomes problematic when a paver patio which needs a hundred percent compaction putts right up to a retaining wall it's not uncommon also another thing that can create problems like this is animals they'll dig and burrow underneath the paver patio and create their own void spaces so but there is a way to fix and repair this it's not the end of the world you have to use hand compaction behind a retaining wall meaning you still have to compact behind it because if you let that go it's going to create problems down the road but one of the things that you need to look at in this area is you've seen that pipe when they installed that swimming pool that's behind the guys while they're working whoever installed that pipe didn't compact around their pipe and that created the void spacing which created the settlement issues which created the patio failure when you give a mouse a cookie and so on and so forth so we've taken the time to compact just using light hand hand compaction equipment we can use a basing hammer you can use a packing plate you don't want to use motorized compaction equipment behind your retaining wall because you can blow out that retaining wall and then not only are you repairing a patio you could also be potentially
