Foam-Control Geofoam Update – Calculation Examples,
We are pleased to announce new Foam-Control Geofoam Calculation Examples are now available. The Calculation Examples are a new type of document being provided to support Foam-Control Geofoam. The three introductory examples demonstrate a method to calculate the distribution of structural loads through pavements and base materials to geofoam. In addition, the stress through a geofoam fill can be calculated. The distribution of loads is a critical factor in design and selection of Geofoam for many projects.
- Example 1 – distribution of load from a single 1 ft. x 1 ft. 12,500 lb. load
- Example 2 – distribution of load from two 1 ft. x 1 ft. 12,500 lb. loads spaced 5 ft. apart
- Example 3 – distribution of load from four 1 ft. x 1 ft. 12,500 lb. loads spaced 5 ft. apart laterally and spaced 4 ft. apart longitudinally
The geofoam calculation examples are being provided to illustrate a simplified method for the calculation of vertical stress on geofoam in hypothetical examples. This simplified method is being provided as an example and should not be relied upon for the selection of Foam-Control Geofoam for a particular project. The selection and/or specification of a Foam-Control Geofoam for a specific application should be determined by a qualified design professional who is acquainted with all possible aspects of a particular project.
We are pleased to announce the AFM Laboratory is now ATZ Laboratory.
We will continue to operate ATZ Laboratory out of Lakeville, MN and you will continue to receive the best service, pricing, and reports available to the entire insulation and geofoam industries. The website for the lab is now www.atzlaboratory.com.
AFM Corporation continues to offer industry leading Geofoam testing services to the Geofoam Industry. The AFM Laboratory specializes in conducting testing services for the geofoam industry and takes pride on achieving quick response time at economical pricing due to a focus on ASTM D6817 geofoam testing.
The AFM laboratory is accredited to international standard ISO/IEC 17025, “General requirements for the competence of testing and calibration laboratories”.

ASTM D6817 and ASTM C578 Summary Table
We are pleased to announce a new ASTM D6817 and ASTM C578 Summary Table is now available to demonstrate the primary differences between Foam-Control Geofoam and Foam-Control EPS products.
The key differences between Foam-Control Geofoam and Foam-Control EPS insulation products are:
- Foam-Control Geofoam has requirements for compressive resistance at 1% deformation
- Foam-Control EPS insulation has requirements for compressive resistance at 10% deformation
- Foam-Control EPS insulation has published R-values
We hope you find the new summary table useful to understand the differences between Foam-Control Geofoam and Foam-Control EPS insulations.
ASTM has released an update to ASTM D6817. The latest version is now ASTM D6817-15.
There was an important change with the latest version of ASTM D6817. The values for compressive resistance at 5% and 10% were moved from the main body of the document to the Appendix. This is important since the content of the Appendix is non mandatory. Thus, the compressive resistance for geofoam at 5% and 10% are no longer requirements of the standard. This means that when geofoam is tested for compliance with ASTM D6817-15 the compressive resistance at 5% and 10% is not necessary unless specified by a customer.
Geofoam was used a part of the Maggie Daley Park reconstruction to create hills and landscapes without adding excessive weight to the parking structure underneath. After the geofoam was in place, the topsoil and trees were transported back to their original locations. To move the topsoil and trees without leaving permanent impressions in the geofoam, the construction company used multi-purpose crawler carriers. Workers also planted an extra 700 trees to make the Maggie Daley Park more eco-friendly.

We are pleased to announce the addition of a new project profile to the Foam-Control EPS Geofoam Project Profile library that showcases the use of Foam-Control EPS Geofoam as a lightweight fill.
Atlanta’s Country Club of the South was renovating a terrace and the project architect and engineer knew the hill near the clubhouse expansion would have to be carved out. A fill material that would prevent pressure on the downslope and create a stable foundation for the large terrace was needed. Foam-Control EPS Geofoam was the solution.
The Foam-Control EPS was supplied by ACH Foam Technologies.
We are pleased to announce an updated UL Evaluation Report (issued 6/1/13) for Foam-Control EPS Insulation and Geofoam products is now available.
The update to the UL Evaluation Report includes:
- Recognition of Perform Guard and Perform Guard2 termite resistant products
- Recognition of use in attics and crawl spaces without an ignition barrier
The Foam-Control UL Evaluation Report now includes complete recognition of Foam-Control EPS insulation in a manner similar to the ICC-ES ESR-1006. However, the UL Evaluation report has the additional benefit of recognition of Foam-Control EPS Geofoam.
It is intended to add Foam-Control Geofoam recognition to ICC-ES ESR-1006 in the future, but it is not possible at this time since ICC-ES has not yet developed an Acceptance Criteria. An ICC-ES Geofoam Acceptance Criteria is currently under development, but until such time that it is approved the UL ER11812-01 should be used for geofoam applications in buildings.
We are pleased to announce an updated UL Evaluation Report (issued 4/10/13) for Foam-Control EPS Geofoam is now available. The update to the UL Evaluation Report includes recognition of Jebsen and Jessen Packaging in Singapore.
Jebsen and Jessen Packaging joins Shanghai Broadway Packaging and Insulation Materials (China) and Poliestireno Alfa-Gamma (Mexico) as international locations for Foam-Control EPS Geofoam covered by the UL Evaluation report.
We are pleased to announce an updated UL Evaluation Report (issued 2/25/13) for Foam-Control EPS Insulation and Geofoam products is now available.
The updates to the UL Evaluation Report include:
- Recognition of ASTM C578 Insulation Types XI, XIV, and XV
- Recognition of ASTM D6817 EPS12, EPS39, and EPS46 Geofoam
The UL ER11812-01 Evaluation Report is the first third party recognition available anywhere for all seven ASTM C578 Insulations “Types” and all seven ASTM D6817 Geofoam “Types”.
