A transparent liquid waterproofing system is a water repellent surface treatment made up of a solvent and a polymer. The solvent is typically a petrolatum or a mineral oil based liquid, and the polymer is typically a EVA or a polyurethane resin. The system cures to form a hard coating that is resistant to water and other chemicals.

Sand Membrane is a term sometimes used to refer to a waterproofing system that involves the application of a membrane (typically bituminous) with a layer of sand on top. The sand is often used to protect the membrane from damage, provide a non-slip surface, and improve adhesion for subsequent layers of concrete or other materials.

Mineral Membrane refers to waterproofing membranes that are reinforced with mineral particles. These membranes are often used in roofing and other exposed areas where they provide durability and resistance to the elements.
