What does PMBC/KMB compound mean?

PMBC compounds (German KMB: Kunststoffmodifizierte Bitumen-Dickbeschichtung) are polymer-modified thick-layer bituminous compounds. Acronym PMBC (Polymer modified bituminous thick coatings for waterproofing ) is used more often after the introduction of the EN 1504-2 Standard.

These are solvent-free, one- or two-component compounds used to make seamless waterproofing coatings of nearly any type, incl. foundations.
