5.1 This guide informs the user of design considerations in the use of EPS geofoam which assist in the determination of the appropriate EPS geofoam for geotechnical applications.

5.2 This guide does not preclude the judgment and practice of those competent in geotechnical design.

1.1 This guide covers some of the basic considerations for the use of expanded polystyrene (EPS) geofoam in geotechnical projects.

1.2 This guide offers a collection of information and does not recommend a course of action. This guide cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances.

1.3 This guide is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this guide be applied without consideration of a project’s many unique aspects.

1.4 The word “standard” in the title of this guide means only that this guide has been approved through the ASTM International consensus process.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
