SECTION 1
INTRODUCTION
1.1
This document provides procedures for the Installation of CETCO
GCLs in a manner that maximizes safety. efficiency, and the
physical integrity of the GCL.
1.2
These guidelines are based upon many years of experience at a
variety of sites and should be generally applicable to any type of
lining project using CETCO GCLs. Variance from these guidelines
is at the engineer's discretion.
1.3
The performance of the GCL is wholly dependent on the quality
of its installation. It is the Installer's responsibility to adhere
to these guidelines, and to the project specifications and
drawings as closely as possible. It is the engineer's and owner's
responsibility to provide construction quality assurance (CQA)
for the installation. This will ensure that the installation has
been executed properly. This document covers only installation
procedures.
1.4
For additional guidance, refer to ASTM D5888 (Standard Guide
For Storage and Handling of Geosynthetic Clay Liners) and ASTM
D 6102 (Standard Guide For Installation of Geosynthetic Clay Liners).
SECTION 2
EQUIPMENT REQUIREMENTS
2.1
CETCO GCLs are delivered in rolls typically 2,600 -2,950 lbs
(1180 -1340 kg). Roll dimensions and weights will vary with the
dimensions of the product ordered. It is necessary to support
this weight using an appropriate core pipe, as indicated in Table
1. For any installation, the core pipe must not deflect more than
3 inches (75 mm), as measured from end to midpoint when a full
GCL roll is lifted.
2.2
Lifting chains or straps appropriately rated should be used
in combination with a spreader bar made from an I -beam, as
shown in Figure 1.
2.3
The spreader bar ensures that lifting chains or straps do not
chafe against the ends of the GCL roll, allowing it to rotate freely
during installation. Spreader bar and core pipe kits are available
through CETCO.
2.4
A front end loader, backhoe, dozer, or other equipment can be
utilized with the spreader bar and core pipe or slings. Alternatively,
a forklift with a "stinger" attachment may be used for on -site
handling. A forklift without a stinger attachment should not be
used to lift or handle the GCL rolls. Stinger attachments (Figures
2 -4) are specially fabricated to fit various forklift makes and
models.
