BS EN 15812 is a European Standard on polymer-modified bituminous thick coatings for waterproofing. The main aim of the BS EN 15812 series is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of your civil engineering works.
BS EN 15812 specifies two methods (method A and method B) for determining the crack bridge
properties of polymer modified bituminous thick coatings for waterproofing. The two test methods may be applied equally.
BS EN 15812 on polymer modified bituminous thick coatings is useful for:
Bitumen is one of the earliest and most popular forms of waterproofing as it moves with the structure and does not allow water to come inside the structure.
Crack bridge ability is an ability of a product to bridge a crack and maintain the water tightness performance under specified conditions and without damage.
In this regard, BS EN 15812 provides the requirements of apparatus, test sampling, test method and procedure on polymer-modified bituminous thick coatings for waterproofing.
Thus, if you are a manufacturer of bituminous products, complying with BS EN 15812 can help demonstrate the performance of your product, ensuring that they are fit for purpose.
Overall, determining crack-bridging capabilities of bituminous materials can evaluate whether they are suitable for applications requiring coating elasticity for waterproofing, thus contributing to enhanced service-life of your construction works.
