Long-term waterproofing typically uses high-residue bitumen emulsions, often polymer-modified or rubber-modified, designed to form flexible, continuous films after curing. These formulations prioritize adhesion, crack-bridging ability, water resistance, and aging stability rather than rapid breaking. Controlled breaking behavior, higher solids content, and compatibility with substrates such as concrete, masonry, and metal are essential for durable waterproof coating performance.
