Waterproofing is always the one thing that gets left off or ignored by most disciplines, hoping that someone else is doing it. In the absence of a waterproofing consultant, waterproofing of a fountain can be accomplished in a number of ways:
- Integral to the concrete: With admixtures and higher compressive strength pours, concrete can be made waterproof. This would put the scope within the structural engineer’s work.
- Topical application: Depending on which kind of product is used, the concrete is coated with material to make it watertight. The product can be either fluid-applied or cementitous. If fluid-applied material is used, its compatibility with the methods of attachment for the finishes must be considered. This scope is usually under the architect, landscape architect or structural engineer.
- Topical application, part of grouting system: Some manufactures have complete systems to waterproof basins that work with a waterproofing material, a leveling bed and a mortar and grout system for the finishes. This scope is under the architect or landscape architect responsible for the finishes.
