Hello ~ I'm going to build a fish pond in the basement to raise ornamental fish when I go home. How to construct it and how to make it waterproof is better?

score is not a problem! If brick is used, mortar batch should be used on the surface, preferably waterproof mortar batch, and then waterproof can be done. After that, brick can be stuck again. Because waterproof is done on mortar, it is recommended to use cement-based waterproof coating, which has good compatibility with mortar and is non-toxic. The key is that the bricks are firm. I don't need to talk about building and batch of mortar. When waterproof mortar is made, just do it yourself, and apply more in the internal corners. Remember, the maintenance of mortar and waterproof is the key. The joint between brick and concrete is the same. It is best to plant a few steel bars, so that the facade is fixed better and waterproof is guaranteed. There is no difference between sticking bricks on cement-based waterproofing as it is on concrete. Contact if you have any questions!
