| Re: Building a water channel
I do not know what you have heard about sand and cement mix, but I have never had any troubles by using it, including my own pond and others I have built for customers. I would of thought that once it has gone off it will be inert and cause no problems. That is my experience anyway. I would recommend using a waterproofing agent in the mix as pug (mortar) is not fully waterproof. Check the waterproofing agent is ok to use though. If you need any help regarding sand cement, give me a shout, I work with it...................Jon |
