Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

This document was prepared by Technical Committee ISO/TC 221, Geosynthetics.
This second edition cancels and replaces the first edition (ISO 13426-1:2003), which has been
technically revised. The main changes compared to the previous edition are as follows:
— Clauses 2, 5, 6, 7, 8 and all the figures have been technically revised.

Introduction
Geocells are geotextile-related products composed of single strips interconnected in several possible
ways (extrusion, thermal bonding, gluing, hot melt, stitching, etc.) to form a panel of adjacent cells,
where generally the contact between two elements occurs along lines or in specific points, and not
uniformly on the whole surface. These lines or points are referred to as "junctions".
A geocell junction can fail in four different ways:
1) by shear (see Figure 1): when failure is caused by a force parallel to the junction itself;
2) by peeling or delamination (see Figure 2): when failure is caused by a force, normal to the junction,
which separates the cells from each other at one edge of the junction;
3) by splitting (see Figure 3):
