Hi everyone,
First time here and first post but love your site after spending the morning on it!
Here goes:
I've been brought in to bid on building a retention wall around a new pond that's under construction. Finished pond will be 1.5 ish acres. The goal is to build a 10' boardwalk out of pavers around the pond. On the inside of the boardwalk (pond side), they asked if we could build a retention wall to be finished under water so that it would serve as a wall for my boardwalk to build off of. If we go this route the concrete blocks would be submerged almost 2' year round. The blocks are heavier duty than HD blocks, they are old castle with a rough finish. Link is attached to see the blocks we have to use.
My question is: Will the wall last underwater like this? I can pour a footer if needed.
Thanks,
Coby
