cement waterfall erosion

dapo
12 years ago

I have a backyard pond with waterfall. The water coming out of the waterfall runs over a layer of rock and hydraulic cement before splashing into the pond. I noticed that the cement is eroding away rather quickly. There is no leak (at least not yet). I looked at posts on this forum and a few people mention cement sealers for stopping leaks but I have not seen any that talk about slowing down erosion when you have a rapid water flow. Does anyone know if a sealer or something else would slow down the erosion? Thanks.
