Geocomposite Peel Strength Failures Cause Concern Through Geosynthetics Industry (Special Feature)
More than a decade ago, a third-party case study described a geocomposite drainage layer installed as part of a landfill cap system. The project was typical and progressing exactly as planned with all appropriate construction and installation procedures being followed according to standard industry practice. Yet, as the filler sand was being placed on the composite, onsite construction quality assurance personnel began noting a tearing sound. Somehow, this geocomposite that had passed all standard testing of the time was failing as the geotextile was actively delaminating from the geonet. How could this happen?
In late 2018, Richard Thiel published a follow-up article discussing the shortcomings of the test methods used in ASTM D7005 ‘Standard Test Method for Determining the Bond Strength (Ply Adhesion) of Geocomposites’.  To summarize, he shows that there is significant variability of peel strength across a roll width. For this reason, the five samples required for ASTM D7005 is likely to overlook potential defects in the geocomposite as it did more than a decade ago.

Raven Release Annual Report 2019 (Declassified)
Engineered Film’s operating income decreased by 16.1% to $39.7 million from $47.3 million in the prior year. The decrease in operating income was led by lower plant utilization from the reduction in hurricane recovery film sales and approximately $2 million of cost over-runs on a large geomembrane installation project that was completed in the fourth quarter of fiscal 2019.  The geomembrane  and construction markets had the largest increases in net sales, but all markets were up year-over-year. Engineered Films achieved sales growth due to improved end-market demand and increased market share. Delivery of hurricane recovery film to support relief efforts and the recent acquisition of CLI contributed net sales of $24.2 million and $13.1 million, respectively.

Raven Industries’ RPE geomembrane Selected to Resist Failure from Rapid Drawdown
This proved challenging because there are few geomembranes that can withstand the design rapid drawdown
The Taproot Storage Pond is a fresh water storage pond intended to service oil fields in Northeastern Colorado.  This pond also had a rapid drawdown design issue because the drilling process utilizes a large volume of water for the oil/gas well development.  The bottom liner system consists of a geomembrane placed on the existing fine-grained soils that had to be ballasted to prevent failure during rapid drawdown. Also designed by J & T Consulting, with civil operations performed by Northern Colorado Constructors, this project posed many challenges from a design and construction standpoint.  A geomembrane that could not only withstand the harsh chemical and windy conditions of the eastern Colorado plains, but also could be installed in a short installation window, was needed.  Raven Industries’ 45 mil thick RPE geomembrane (see Figure 5) was used because of its durability and longevity in harsh conditions, as well as designing of an integrated ballast system for the slopes that would ensure that the high winds and rapid drawdown would not affect liner system integrity.

Geomembrane Durability Study
Geomembrane samples were previously collected and tested after two, four, five, ten and twenty years in the basin, and the materials still meet the original specifications. Following the retrieval of the 20-year samples, it was determined that there was sufficient space available in the basin to install additional materials. After discussions with the MN DNR, it was decided to install eight new materials with dimensions of 6-feet (1.8-m) wide and 25-feet (7.6-m) long. These samples also contained a seam at the centerline, but all seams were created using a thermal welder. The FGI and the MN DNR installed eight additional geomembrane material samples on the bottom of the mine settling. The eight new geomembranes installed are:
* 36-mil reinforced polypropylene, provided by Cooley Group (CG)
* 30-mil single film laminated woven coated polyethylene, provided by Owens Corning Inc. (OC)
* 30-mil single scrim coated woven coated polyethylene, provided by Intertape Polymer Group (IPG)
* 40-mil unreinforced LLDPE, provided by Raven Industries (RI)
* 30-mil XTRM Ply ethylene interpolymer alloy (EIA) formulation geomembrane, provided by Engineered Polymer Technologies (EPT)
* 30-mil XR-5 ethylene interpolymer alloy (EIA) formulation geomembrane, provided by Seaman Corporation (SC)
* 30-mil PVC geomembrane, provided by Plastatech Inc. (PI)
* 30-mil smooth HDPE geomembrane, provided by GSE Environmental (GE)
