IS 16090 : 2013 : Geo-Synthetics - Geo-Textiles Used as Protection (or Cushioning) Materials - Specification
Reaffirmed 2023
1 SCOPE
1.1 This standard specifies requirements for needlepunched non-woven geo-textiles used as protection (or cushioning) materials adjacent to (above and/or below) a geo-membrane to protect it from construction and operational damage in typical applications including solid waste landfills and liquid impoundments with varying load, sub-grade and cover sub-grade soil conditions.
NOTE - The typical use shall be as a protective covering or underlayment of a geo-membrane against puncture or tear due to rock, stones, concrete or other hard surfaces and/or objects.
1.2 This standard covers physical, mechanical and endurance properties that must be met, or exceeded by the geo-textile.
1.3 This is a material purchasing specification and design review of its use for intended applications is recommended. This is not a construction or design specification. Protection (cushioning) of geomembranes is a site specific design issue which should be addressed by the engineers responsible for the site design.
1.4 This standard is based on the minimum requirements of the geo-textile to provide tensile reinforcement and survivability from installation stress. In general, the geo-textile shall be placed at the proper elevation, location and orientation as detailed on the plans and specification.
1.5 The design, installation and construction guidelines for such geo-textiles are being published as a separate Indian Standard.
