- This is PART 1 of our retaining wall project. Many people have used this method above water, but we decided to try it below the water. Subscribe for updates and more.

How did you prepare the footing -- below the first course
Some areas had to be excavated and others built up. Crushed concrete base and gravel for build up. Thanks for watching.
OK what am I missing here? Don't you have to break the paper for the rows to stick together?
@@NickyTheLesser Oh I get that. I was asking how the individual bags bond to each other. Does the 2 layers of paper have zero impact on that? Seems like what we're left with is a bunch of bag shaped concrete rocks with rebar driven through them. Probably that's ok right?
Thanks for watching. You are correct- the bags do not bond to each other without the rebar. A typical dry stack concrete project is essentially using weight, gravity and the intelocking nature of the bags being tightly stacked together. The weight of this wall is somewhere around 5k lbs. The lower rows of bags are not going anywhere due to the weight- similar to the way the lower bricks or blocks in a large stack are held in place simply by the weight of the blocks on top of them. The second thing that holds the wall together is the way the bags conform to each other when stacked. Because the bags are soft they form to each other and become somewhat interlocking. A typical dry stack project will also run the backs slightly backwards with each row so that the stack is leaning on the ground that it is supporting. We chose not to do that in this project because of the additional structure/anchor we built behind the wall. These bags are paper only (no plastic liner) so they will allow water to fill the bags and absorb into the concrete. In addition to the basic design that is used for stack concrete walls we added the rebar to more positively lock the bags together. It would be possible to form and pour a wall for a seawall, block a wall up, or use a metal seawall system, but those would be a significantly higher investment in time and labor and is not very practical for a DIY project. This wall is in Florida- and this year had the chance to be tested with two direct hits from hurricanes. The storms had no negative effects on the wall. Thanks for watching and for the questions!
@@travelbuildcreate Ah thank you! Makes sense.
is there an update yet?
Video update coming soon. The wall is now complete and had the chance to be tested in two hurricanes. It held strong and experienced no problems.
