Underwater concrete repair of slab
Underwater concrete repair of slab
(OP)
I have a boat ramp that extends underwater. The last section, 2' under the waterline, is broken up and needs to be replaced. Anyone have any experience pouring concrete under 2' of water? (The area in need of repair is about 2' x 3') Is this possible, and if so, any tips (mix additives, process, etc.) you could relay would be great!!
Thanks...
Thanks...

Thanks for the feedback...I think based on the size of the hole, I'll try pouring through a pipe. As far as the top goes, maybe a weighted down sheet of plywood over the pour will give me a reasonable surface (at least good enough for trailer tires).
The tremie article was helpful.
