What is BS EN 13493 - Geosynthetic barriers in the construction of solid waste storage and disposal sites about?
BS EN 13493 specifies the characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separation layers in the construction of solid waste storage and disposal sites, and the appropriate test methods to determine these characteristics.
The intended use of these products is to control the leakage of fluids through the construction. BS EN 13493 provides the assessment and verification of constancy of performance (AVCP) of the product including factory production control procedures.
NOTE: BS EN 13493 is not applicable to geotextiles or geotextile-related products.
Who is BS EN 13493 - Geosynthetic barriers in the construction of solid waste storage and disposal sites for?
BS EN 13493 on geosynthetics is useful for:
- Manufacturers and suppliers of geosynthetic materials
- Civil engineers
- Manufacturers of polymers, clays and bituminous products
Why should you use BS EN 13493 - Geosynthetic barriers in the construction of solid waste storage and disposal sites?
A geosynthetic barrier is a barrier with at least one of whose components is made from a synthetic or natural polymer, in the form of a sheet, a strip or a three-dimensional structure, used in contact with soil and/or other materials in geotechnical and civil engineering applications.
BS EN 13493 navigates you through the characteristics and corresponding methods of testing geosynthetic barriers used in the construction of solid waste storage and disposal sites to prevent or reduce the flow of fluid through the structure. BS EN 13493 specifies the physical and mechanical properties of geosynthetic materials, as well as the test techniques for determining them. Assessment and verification of constancy of performance (AVCP) on the compliance of geosynthetic barriers for use in the construction of solid waste storage and disposal sites are given in BS EN 13493. BS EN 13493 provides guidance on the factory production control (FPC) system to ensure that the products placed on the market comply with the declared performance of the essential characteristics.
Overall, BS EN 13493 instructs you on the features of geosynthetic materials that prevent leakages and ensure the longevity of geosynthetic barriers used in solid waste storage and disposal sites construction for the satisfactory performance of barrier systems. In this way, geosynthetic materials can be used to function efficiently, ensuring flexibility, mechanical strength, frost and heat resistance, availability through industrial manufacturing, and ease of workability, resulting in the long-term performance of solid waste storage and disposal sites.
