What is BS EN 14691 - Compatibility of the waterproofing system by heat conditioning about?
BS EN 14691 is a European standard applicable to flexible sheets for waterproofing of concrete bridge decks and other concrete surfaces trafficable by vehicles.
BS EN 14691 specifies a test method for the evaluation of the compatibility of the waterproofing system applied to a concrete surface and covered with an asphalt layer.
The complete system is exposed to accelerated heat conditioning followed by a determination of the shear strength properties before and after heat conditioning.
Who is BS EN 14691 - Compatibility of the waterproofing system by heat conditioning for?
BS EN 14691 on flexible sheets for waterproofing is useful for:
- Manufacturers and suppliers of sheet and waterproofing materials
- Concrete manufacturers
- Manufacturers of asphalt products
- Manufacturers of building binders and sealing materials
Why should you use BS EN 14691 - Compatibility of the waterproofing system by heat conditioning?
The use of the shear resistance test will allow the determination of any change in properties together with an indication of any migrational or interfacial long-term incompatibility between the adherents.
BS EN 14691 provides the requirements on apparatus and materials used for testing the compatibility of flexible sheets for waterproofing.
Preparation of test specimens and test procedure is described in BS EN 14691 to test the shear resistance property of waterproofing sheets.
BS EN 14691 specifies the method for calculation of compatibility and shear resistance for each test specimen and test report on information about sampling, preparation, drying and conditioning of test specimens.
Overall, BS EN 14691 provides guidance for effective waterproofing design in order to prevent water from entering or escaping from various areas of the building structure while assuring water absorption and permeability, shear strength, and tensile strength of the waterproof bonding layer.
This way, you can acquire effective waterproofing systems that completely enclose all regions subjected to hydrostatic pressure and chemical contaminants.
