What material should I use to fix the cracks in the waterfall spillway? The water escapes through the cracks when I turn on the falls and spills into the adjoining garden. I see three kinds of material that were used and the whole spillway needs repair.
Should I use a pre-mixed grout mix from a local hardware store. I see something like Polyblend and also some premixed products.
Are both unsanded grout and sanded grout waterproof?
Should I apply sanded grout for large cracks and apply unsanded grout on top of it?
It looks like some epoxy material was used in the past to cover and seal the cracks. Are they better than sanded grout?
