Polymer Modified Bituminous Thick Coatings for Waterproofing: Determination of Crack Bridging Ability
Also Known As:
BS EN 15812:2011 is a standard that provides two methods (method A and method B) for determining the crack bridging ability of polymer modified bituminous thick coatings used for waterproofing purposes. The crack bridge properties refer to the ability of the coating to resist crack formation and propagation, thereby maintaining its waterproofing performance.
The two test methods, method A and method B, can be used interchangeably and are designed to evaluate the crack bridging ability of the coating. Both methods involve subjecting the coated specimen to controlled deformation, such as elongation or bending, and measuring the resistance of the coating to crack formation and propagation under these conditions.
The purpose of this standard is to ensure that polymer modified bituminous thick coatings used for waterproofing meet certain performance requirements regarding crack bridging ability. By determining the crack bridge properties of these coatings, this standard aims to provide manufacturers, specifiers, and users with reliable information to assess the quality and effectiveness of the coating in preventing water ingress through cracks.
