achieved solely through needlepunching, without any supplemental heat treatment. E. The GCL shall have 10,000-hour test data for large-scale constant-load (creep) shear testing under hydrated conditions. The displacement shall be 0.11 in. (2.7 mm) or less at a constant shear load of 250 psf(12 kPa) and a normal load of 500 psf(24 kPa). F. The GCL shall have seam test data from an independent laboratory showing that the seam flow with a grooved cut in the nonwoven geotextile is less than 1 x 10"$ m3/m2/s at 2 psi hydraulic pressure. G. The minimum acceptable dimensions of full-size GCL panels shall be 150 feet (45.7 m) in length. Short rolls [(those manufactured to a length greater than 70 feet (21 m) but less than a full-length roll)] may be supplied at a rate no greater than 3 per truckload or 3 rolls every 36,000 square feet (3,500 square meters) of GCL, whichever is less. H. A 6-inch (150 mm) overlap guideline shall be imprinted on both edges of the upper geotextile component of the GCL as a means for providing quality assurance of the overlap dimension. Lines shall be printed in easily visible, non-toxic ink. 2.2 Product Quality Documentation The GCL manufacturer shall provide the Contractor or other designated party with manufacturing QA/QC certifications for each shipment of GCL. The certifications shall be signed by a responsible party employed by the GCL manufacturer and shall include: A. Certificates of analysis for the bentonite clay used in GCL production demonstrating compliance with the swell index and fluid loss values shown in the Bentomat ST Certified Properties table. B. Manufacturer's test data for the finished GCL product demonstrating compliance with the values shown in the Bentomat ST Certified Properties table. C. GCL lot and roll numbers supplied for the project (with corresponding shipping information). Manufacturer's test data for finished GCL product(s), including GCL index flux, permeability and hydrated internal shear strength data, which demonstrate compliance with the performance.parameters shown in the Bentomat ST Certified Properties table, are available upon "request of the manufacturer. 2.3 Product Labeling A. Prior to shipment, the GCL manufacturer shall label each roll, identifying: 1. Product identification information (Manufacturer's name and address, brand product code). 2. Lot number and roll number. 2870 Forbs Avenue Hoffman Estates,'IL 60 .92 847.851.1800;1 800.527.9948 www.CETCO.com
