Submersed bags of concrete

I'm attempting to stop the erosion of my creek bank by lining bank with bags of concrete, will a submersed bag of concrete harden?

Welcome to the diy forums!

Concrete will harden under water. I don't know how it affects the strenght of the concrete. Might be better to ask in the masonary section.

You may want to check and find out if it's legal for you to shore up the creek bank. My brother in-law had the creek rise and flood his pasture. He hired a back hoe to reroute the creek back to the way it had been. Not sure how he got caught or the exact agency that contacted him but they made him put back everything the way it was after the creek flooded. They said he had interrupted nature.

They do that a lot. It works real good . Have used it a lot for around drain pipes under driveways. After you say lay the wall we drive 3/8" rebar down through all the sacks there. Lay them as you would cement blocks.
Sorry about that yes it has to be the bags of premixed concrete .

It will get harder, but not like a rock since there is no sand or rock in it. If it is a bag of premixed concrete, then it will get hard.

It is a very expensive way to solve the problem.

Buy some rock or retaining wall block. - Its cheaper and looks better.

You can also buy bagged rip-rap in special decomposing bags, but either way it is an expensive, ugly solution.
