PVC Geomembrane Fabrication and Installation Specification
09/06/2006
After more than two years of intensive revision by the PVC Geomembrane Institute (PGI), the Fabrication and Installation Specification for PVC Geomembranes is complete.
The specification addresses the relevant topics for fabrication and installation of PVC geomembranes including: submittals, qualifications, geomembrane packaging and shipping, on-site placement conditions, factory and field seaming, geomembrane warranty, field quality control, anchor trench construction and backfilling, and safely covering the geomembrane. Some of the issues specifically addressed during the revision process include air channel testing of field seams, new ASTM material specification for PVC geomembranes, and destructive field seam testing.
The Specification is designed for specifiers and designers to use directly in project-specific documents or for simply attaching to project-specific documents. The new Fabrication and Installation Specification for PVC Geomembranes can be accessed by clicking the link below.

HDPE Geomembrane CQA (Construction Quality Assurance) Plan
01/01/2005
This "CQA Plan" for HDPE geomembranes was originally prepared for those projects in which the project specifications were inadequate so therefore also includes project specifications. It will shortly be divided into separate project specifications and a CQA Plan. Note that the objective of CQA is to ensure that the liner is built according to the project specifications, with the best possible workmanship, and within the constraints of the budget and schedule. CQA does NOT ensure a perfect lining system. If the liner is poorly designed, CQA will ensure that that poorly designed liner is installed. CQA should contribute positively to the quality of the lining system, it should not be only a glorified data collection system. This CQA Plan is ready for immediate use. It just requires a few project specific details to be added. Text (that can be erased) provides some guidance on the project specific information required.

GRI.GM17 Standard Specification for Test Properties, Testing Frequency and Recommended Warranty for Linear Low Density Polyethylene (LLDPE) Smooth and Textured Geomembranes
05/29/2003
1. Scope
1.1 This specification covers linear low density polyethylene (LLDPE) geomembranes
with a formulated sheet density of 0.939 g/ml, or lower, in the thickness range of
0.50 mm (20 mils) to 3.0 mm (120 mils). Both smooth and textured geomembrane
surfaces are included.
1.2 This specification sets forth a set of minimum, maximum, or range of physical,
mechanical and endurance properties that must be met, or exceeded by the
geomembrane being manufactured.
1.3 In the context of quality systems and management, this specification represents
manufacturing quality control (MQC).
Note 1: Manufacturing quality control represents those actions taken by a
manufacturer to ensure that the product represents the stated
objective and properties set forth in this specification. 1.4 This standard specification is intended to ensure good uniform quality LLDPE
geomembranes for use in general applications.
Note 2: Additional tests, or more restrictive values for the tests indicated,
may be necessary under conditions of a particular application. In
this situation, interactions with the manufacturers are required.
Note 3: For information on installation techniques, users of this standard
are referred to the geosynthetics literature, which is abundant on
the subject.

GRI.GM14 Selecting Variable Intervals for Taking Geomembrane Destructive Seam Samples Using the Method of Attributes
05/29/2003
1. Scope
1.1 This guide is focused on selecting the spacing interval for taking destructive seam
samples of field deployed geomembranes as a particular job progresses based on an
installers ongoing record of pass - or - fail testing.
Note 1 - While subjective at this time, the guide is most applicable to large
geomembrane seaming projects which require more than 100 destructive
seam samples based upon the typical sampling strategy of 1 destructive
sample per 150 m (500 ft).
1.2 This guide is essentially applicable to production seams. Caution should be exercised in
using the guide for projects that involve complex geometries, multiple penetrations, or
extreme weather conditions.
1.3 The primary target audiences for this guide are construction quality assurance (CQA)
organizations, construction quality control (CQC) organizations, facility
owner/operators and agency regulators having permitting authority. 1.4 The outcome of using the guide rewards good seaming performance resulting from a
record of passing destructive seam tests. It also penalizes poor seaming performance
resulting from a record of excessively failing seam tests.
1.5 This guide does not address the actual seam testing procedures that are used for
acceptance or failure of the geomembrane seam test specimens themselves. Depending
on the type of geomembrane being deployed one should use ASTM D4437, D3083,
D751 and D413 for testing details in this regard. The project-specific CQA plan should
define the particular criteria used in acceptance or failure.
1.6 An appendix is offered using control charts which is intended to be of assistance to
geomembrane installers, i.e., construction quality control (CQC) organizations, to
identify salient aspects of good and poor seaming performance.

GRI.GM13 Standard Specification forTest Properties, Testing Frequency and Recommended Warranty for High Density Polyethylene (HDPE) Smooth and Textured Geomembranes
05/29/2003
This specification was developed by the Geosynthetic Research Institute (GRI), with the cooperation of the member organizations for general use by the public. It is completely optional in this regard and can be superseded by other existing or new specifications on the subject matter in whole or in part. Neither GRI, the Geosynthetic Institute, nor any of its related institutes, warrant or indemnifies any materials produced according to this specification either at this time or in the future.
1. Scope
1.1 This specification covers high density polyethylene (HDPE) geomembranes with a formulated sheet density of 0.940 g/ml, or higher, in the thickness range of 0.75 mm (30 mils) to 3.0 mm (120 mils). Both smooth and textured geomembrane surfaces are included.
1.2 This specification sets forth a set of minimum, physical, mechanical and chemical properties that must be met, or exceeded by the geomembrane being manufactured. In a few cases a range is specified.
1.3 In the context of quality systems and management, this specification represents manufacturing quality control (MQC).
Note 1: Manufacturing quality control represents those actions taken by a manufacturer to ensure that the product represents the stated objective and properties set forth in this specification.
1.4 This standard specification is intended to ensure good quality and performance of HDPE geomembranes in general applications, but is possibly not adequate for the complete specification in a specific situation. Additional tests, or more restrictive values for test indicated, may be necessary under conditions of a particular application.
1.5 This specification also presents a recommended warrant which is focused on the geomembrane material itself.
1.6 The recommended warrant attached to this specification does not cover installation considerations which is independent of the manufacturing of the geomembrane.

Lining Transformer Secondary Containment Structures: EIA Geomembrane Construction Quality Assurance Plan
02/26/2003
This construction quality assurance (CQA) plan provides guidance to (COMPANY NAME)’s environmental quality control (QC) and quality assurance (QA) personnel (or their representatives) and their contractors involved with the installation of geomembrane lining systems in existing concrete secondary containment structures, such as under transformers. This document specifically covers the use of PVC – KEE (ketone ethylene ester) alloy geomembranes. The premise of geomembrane lining systems is that the geomembrane functions solely as a barrier and not a load-bearing member of the system.
