Standard Practice for Exposure and Retrieval of Samples to Evaluate Installation Damage of Geosynthetics
SIGNIFICANCE AND USE
5.1 The ability to maintain design function (for example, reinforcement, separation, barrier, etc.) or design properties (for example, tensile strength, chemical resistance, etc.), or both, of a geosynthetic may be affected by damage to the physical structure of the geosynthetic due to the rigors of field installation. The effect of damage may be assessed by analyzing specimens cut from sample(s) retrieved after installation in a representative test section. Analysis may be performed with visual examination or laboratory testing of specimens from the control sample(s), and from the exhumed sample(s).
5.2 A uniform practice for installing and retrieving representative sample(s) from a test section is needed to assess installation damage using project-specific or generally accepted, representative materials and procedures. Damage of a specific grade and type of geosynthetic under specific installation procedures may be assessed with sample(s) exhumed from a full-scale test section.
SCOPE
1.1 This practice covers standardized procedures for obtaining samples of geosynthetics from a test section for use in assessment of the effects of damage immediately after installation caused only by the installation techniques. The assessment may include physical testing. This practice is applicable to any geosynthetic except those installed between layers of aggregate or soil modified by a binder.
Note 1: The binder would inhibit the retrieval of the geosynthetic without inflicting further damage to the geosynthetic. Other practices may be suitable for retrieving geosynthetics used in these applications but are out of the scope of this practice.
1.2 This practice is limited to full-scale test sections and does not address laboratory modeling of field conditions. This practice does not address which test method(s) to use for quantifying installation damage.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D5818-22 is the Standard Practice for Exposure and Retrieval of Samples to Evaluate Installation Damage of Geosynthetics. Developed by ASTM International, this standard provides a uniform practice for installing and retrieving representative geosynthetic samples from full-scale test sections, enabling the assessment of potential installation damage. Geosynthetics-including geotextiles, geomembranes, and related polymeric materials-are widely used in construction for separation, reinforcement, barrier, and drainage functions. Their performance may be compromised by physical damage incurred during typical construction activities such as placement, compaction, and cover material installation.
ASTM D5818-22 outlines the procedures for exposing geosynthetics to actual field installation conditions and retrieving the samples for subsequent analysis, either visually or via laboratory testing. This practice supports the validation of a material's ability to maintain its intended properties and structural function immediately after installation.
Key Topics
Sample Installation and Retrieval Procedures
- Defines how to install geosynthetics in a test section using project-specific or generally accepted materials and methods.
- Details procedures for marking, exhuming, and documenting samples to ensure accurate assessment and reproducibility.
Damage Assessment
- Focuses on evaluating installation damage by comparing exhumed samples with control (uninstalled) samples.
- Outlines the need for thorough documentation of all construction procedures and sample identification.
Applicability
- Applicable to most geosynthetics except those installed between binders or stabilized soils and aggregates.
- Limited to full-scale field sections-does not cover laboratory simulation or specific quantification test methods.
Reporting and Documentation
- Specifies requirements for reporting the test section construction, material identification, testing performed, and any deviations or notable damages.
Applications
ASTM D5818-22 is utilized across a range of geotechnical and civil engineering applications that incorporate geosynthetics. Typical use cases include:
- Ensuring Geosynthetic Performance:
Validates the durability of geosynthetics post-installation in projects such as roadways, embankments, retaining walls, landfills, and other soil-structure systems. - Quality Assurance:
Supports project owners, engineers, and contractors in verifying that installation techniques do not cause unacceptable damage that could jeopardize the effectiveness of the geosynthetic material. - Specification Development:
Helps manufacturers and specifiers establish or refine material and installation specifications based on representative, real-world installation damage data. - Compliance and Forensic Evaluation:
Used for regulatory compliance or investigation when field performance issues are suspected to be linked to installation-related damage.
Related Standards
For broader context and comprehensive quality management when working with geosynthetics, ASTM D5818-22 references and aligns with several related standards, including:
- ASTM D123 - Terminology Relating to Textiles
- ASTM D4439 - Terminology for Geosynthetics
- ASTM D4873/D4873M - Guide for Identification, Storage, and Handling of Geosynthetic Rolls and Samples
These complementary standards provide essential definitions and guidelines that support consistent material handling, terminology, and project reporting.
Conclusion
ASTM D5818-22 plays a vital role in the effective use of geosynthetics by standardizing the processes for evaluating installation damage. By following this practice, stakeholders gain reliable, project-specific data ensuring geosynthetics are properly assessed and capable of fulfilling their intended design roles. This enhances confidence in geosynthetic installations, helps prevent premature failures, and supports consistent construction quality in infrastructure projects.

4. Summary of Practice
4.1 Damage to geosynthetics from installation operations may be quantified by evaluating specimens from a sample(s) exhumed
from a full-scale installation. The sample(s) should be installed using project-specific procedures and materials. When
project-specific materials and/or procedures are unknown, generally accepted, representative materials and procedures should be
used and thoroughly documented and reported. Addressed within this practice are: amount of geosynthetic sample(s) to install;
procedures for installing the geosynthetic sample(s); procedures for exhuming the geosynthetic sample(s); procedure for obtaining
control sample(s); and report preparation guidelines. The sample(s) should be retrieved immediately after installation to minimize
potential aging of the geosynthetic. Comparison of test results on exhumed and control specimens may be used to assess effects
of installation. Tests to perform are not addressed herein, and will vary with the type and function of geosynthetic and project
requirements.
5. Significance and Use
5.1 The ability to maintain design function (for example, reinforcement, separation, barrier, etc.) or design properties (for example,
tensile strength, chemical resistance, etc.), or both, of a geosynthetic may be affected by damage to the physical structure of the
geosynthetic due to the rigors of field installation. The effect of damage may be assessed by analyzing specimens cut from
sample(s) retrieved after installation in a representative test section. Analysis may be performed with visual examination or
laboratory testing of specimens from the control sample(s), and from the exhumed sample(s).
5.2 A uniform practice for installing and retrieving representative sample(s) from a test section is needed to assess installation
damage using project-specific or generally accepted, representative materials and procedures. Damage of a specific grade and type
of geosynthetic under specific installation procedures may be assessed with sample(s) exhumed from a full-scale test section.
6. Procedure
6.1 Objective—Geosynthetic and soil placement techniques shall model the methods anticipated during construction, but may also
be designed to model hypothetical conditions such as various degrees of compaction, lift heights, drop heights, equipment
operations, and/or types of fill material.
6.2 Exhumed Sample:
6.2.1 The amount of geosynthetic to install in and retrieve from a test section is a function of the type and number of laboratory
tests to be conducted for assessment of damage. An amount of material sufficient to obtain 20 tests on representative specimens
for each type of test should be installed for each set of installation conditions.
6.2.2 The test sample should be marked prior to installation and exhumation, or a template made showing the exact location where
specimens for testing are to be obtained. They shall also be labeled with sufficient information to ensure identification of the
exposed sample and associated exposure conditions, such as geosynthetic and fill type. Machine and transverse-machine direction
of specimens shall be designated. Designation of specimen locations is recommended to eliminate potential bias in specimen
selection after the geosynthetic has been damaged. Alternate areas may also be designated in the event the primary specimen area
is damaged by exhumation.
6.3 Control Sample:
6.3.1 Control or baseline (uninstalled) sample(s) of the geosynthetic being investigated shall be from the same roll of material that
is to be installed in the test section. Sample(s) from each roll of geosynthetic shall be gath
