I'm looking for some type of reference that supports producing a watertight construction joint by sandblasting or water jetting the surface of the first pour to 1)remove laitance, 2)provide roughness, and 3)enable the new pour to bond directly to the first pour's exposed aggregate.
My application is liquid manure storage structures, usually 6' - 12' in depth with 8" - 12" thick concrete walls. Most states require waterstops in such joints which some consider unnecessary.
Thank you.
