Adam, do you know what kind of bricks you've got? And I'm not talking about your splash out last week
Are they blocks with a cleat on one side? Or are these actual bricks, red and rectangular? Or something else? The difference is that one will need mortar in between and the other will not. 10 pallets is a lot of blocks and even more bricks.
Take some time to read about retaining walls and erosion prevention. Usually you would quikrete a foundation, mortar the first layer, and back fill behind the wall with gravel. I doubt that will happen, due to the availability/cost of gravel. But it won't be difficult to put in small drainage pipes. Maybe we can backfill with mulch because w/o the gravel the pipes won't work. Which isn't the best substitution....any ideas what else we could use to serve the same purpose? Too much pressure behind the wall will crumble the work we've done. It also helps rather than blocking off the run-off perpendicular, to redirect the flow of the run-off on an angle.
Please bring gloves, digging and scoop shovels, tarps (you don't mind ruining), wheelbarrows, wide pitchforks, small sections of rustproof pipe (rubber, galvanite, stainless, garden hose, etc.). Got concrete bags or extra mortar laying around?....bring em. Anyone have an atv??? Will the city let us use trucks?
This is physical works guys! Bring your friends!
