Geosynthetic material specifications

Property tables and test methods for the materials we install, referenced to ASTM and GRI standards for spec sections and submittals.

What do these spec pages cover?

Each page below collects the properties, test methods, and selection guidance an engineer or estimator needs to write a spec section or check a submittal for one material family: HDPE geomembrane governed by GRI-GM13, scrim-reinforced polypropylene, woven and nonwoven geotextiles, EPS geofoam classified under ASTM D6817, and baffle curtain systems. Every value comes from published standards or manufacturer data sheets, with the governing ASTM or GRI method cited alongside it.

EC Applications installs each of these materials, so the pages also flag what matters in the field: which thicknesses are actually stocked, where textured sheet earns its cost, and which properties drive seam quality. If you need a full submittal package, or you want us to match an existing project specification, send it over and we will assemble the data and scope the installation as one contract.

Baffle Curtain Systems

Baffle curtain specifications for tanks, basins, and reservoirs: XR, CSPE, and RPP membranes, flotation, ballast, attachment details, and seam QA.
