"Span Seal" is a reactive adhesive waterproofing board that has the property of adhering to fresh concrete as the hydration reaction of the fresh concrete progresses. The adhesion mechanism has been academically elucidated, where the metal oxide ions contained in the cement react with the active groups of Span Seal to chemically bond (adhere).
