C. Acceptable reinforced GCL product is Bentomat® ST, as indicated on the DRAWINGS, and as
manufactured by CETCO, 1350 West Shure Drive, Arlington Heights, Illinois 60004 (847 -392-
5800), or an equivalent approved by the CERTIFYING ENGINEER and DESIGN ENGINEER.
D. The reinforced GCL and its components shall have the properties shown in Table 02776.1 -1.
E. The reinforced GCL shall have 10,000 hour test data for large -scale constant -load (creep) shear
testing under hydrated conditions. The displacement shall be 0.07 inches or less at a constant shear
load of 250 pounds per square foot (psf) and a normal load of 500 psf.
Notes:
1. Bentonite property tests performed at a bentonite processing facility before shipment to GCL production facilities.
2. Bentonite mass /area reported at 0 percent moisture content
3. All tensile strength testing is performed in the machine direction using ASTM D 6768. Upon request, tensile results can be reported
per modified ASTM D 4632 using 4 inch grips.
4. Index flux and permeability testing with deaired distilled/deiomzed water at 80 psi (551kPa) cell pressure, 77 psi (531 kPa) headwater
pressure and 75 psi (517 kPa) tailwater pressure Reported value is equivalent to 925 gal /acre /day. This flux value is equivalent to a
permeability of 5x10 cm/sec for typical GCL thickness. Actual flux values vary with field condition pressures. The last 20 weekly
values pnor the end of the production date of the supplied GCL may be provided.
5. Peak value measured at 200 psf (10 kPa) normal stress for a specimen hydrated for 48 hours. Site- specific matenals, GCL products,
and test conditions must be used to venfy internal and interface strength of the proposed design.
A. The GCL MANUFACTURER shall provide the OWNER and CERTIFYING ENGINEER 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:
1. Certificates of analysis for the bentonite clay used in GCL production demonstrating
compliance with the parameters swell index and fluid loss shown in Table 02776.1 -1.
2. MANUFACTURER's test data for finished GCL product(s) of bentonite mass /area, GCL
tensile strength and GCL peel strength (reinforced only) demonstrating compliance with the
index parameters shown in Table 02776.1 -1.
3. GCL lot and roll numbers supplied for the project (with corresponding shipping
information).
