We are putting together a bid for a canal reshaping project, and have run into an issue that the engineer for the project doesn't have the answer to. How can you place and compact fill on a canal bank that is under water. We can not drain or dewater the canal. We have to add in about 6 feet of canal bank to get to the proposed slope of the bank before placing the rip rap on it, and can not seem to think of a way to do it without lossing much of the materials. Does anyone have any suggestions? Thanks for any info that you may have!
