Geofoam and its Uses- Introduction to Geofaom
- 1. Welcome Geofoam and Its Uses www.pagfoam.com (714) 804-8519 Foamconcepts.net/geofoam (714) 693-1037 Steve Ross Jose Castro Distributor Manufacturer
- 2. EXPANDED POLYSTYRENE GEOFOAM AND ITS USES
- 3. EPS Geofoam Basics – Reduces stresses on underlying soils – Reduces stresses on lateral structures, such as abutments & retaining walls – Very low density, 1% of traditional earth materials – Engineered Product
- 4. EPS Geofoam Basics – High Strength to Density Ratio – Predictable Material Behavior – Meets ASTM Standards – Termite Resistant EPS Geofoam available
- 5. When to Use Geofoam Replaces Other Fill Material – Foamed Concrete – Waste Tires – Soil – Wood Chips – Wood Fiber
- 6. Benefits of Geofoam vs. other fill materials Geofoam • Low Density • Consistent in Makeup • Engineered to meet Expectations • Few limitations • Not Weather Sensitive Other Fill Materials • Higher Density • Variable in Makeup • Not Engineered • Limitation in Handling • Weather Sensitive
- 7. Geofoam Features • Large Block Sizes • Volume Stability • Easily Cut in Field
- 8. What is Expanded PolyStyrene or EPS? • Foamed plastic manufactured from Polystyrene • Available in sheets, blocks, and custom fabricated shapes • Used as insulation and Geofoam
- 9. EPS Performance • EPS has always been free of CFC, HFC, and HCFC blowing agents • EPS contains air • EPS is recyclable • EPS closed cell structure reduces the absorption of moisture • EPS is able to withstand the rigors of temperature cycling, assuring long term performance
- 10. Environmentally Safe • Inert, Non-Nutritive, and Highly Stable • Will Not Decompose or Decay • Will Not Produce Undesirable Gases or Leachates
- 11. EPS Manufacturing Process • Pre-expansion • Molding • Aging • Fabricating
- 12. Product Standards ASTM C578 – Standard Specification for Rigid, Cellular, Polystyrene Thermal Insulation ASTM D6817 – Standard Specification for Rigid, Cellular, Polystyrene Geofoam ASTM E2430 - Standard Specification For Expanded Polystyrene (“EPS”) Thermal Insulation Boards For Use In Exterior Insulation and Finish Systems (“EIFS”)
- 13. Additional Standards ASTM D7557, Standard Practice for Sampling of Expanded Polystyrene Geofoam Specimens ASTM D7180, Standard Guide for Use of Expanded Polystyrene (EPS) Geofoam in Geotechnical Projects
- 14. ASTM D6817 • Standard Specification for Rigid, Cellular Polystyrene Geofoam • Covers Types and Properties
- 15. ASTM D6817 – EPS Types
- 16. Compressive Resistance • The key to performance of Geofoam • 2” cubes according to ASTM D6817 • Independent Testing of Compressive Resistance
- 17. Quality Assurance Programs Third Party Quality Control Program Third Party Testing In-plant QC testing Ongoing lot specific testing
- 18. Termite Resistant EPS for below grade applications • Treated EPS offers built- in resistance to termites • Termite Resistant EPS should meet ICC-ES Acceptance Criteria 239 • Termite Resistant EPS should have an ICC-ES report Termite Damaged Untreated Foams Treated EPS Foam
- 19. Geofoam Applications • Building • Transportation • Utilities • Architectural / Landscape • Other
- 24. Transportation Side Hills with Retaining Wall Retaining Walls
- 25. Utilities –Reduce loads –May eliminate need to move during construction
- 26. Building / Architectural / Landscape Stadium Seating Elevation Changes
- 27. Landscaping
- 28. Projects Millennium Park, Chicago, IL Lightweight fill over parking structure
- 29. Projects Lightweight fill over parking structure Microsoft HQ in Redmond, WA
- 30. Projects Lightweight fill over Water Deposit Rialto, CA
- 31. Projects Yorba Linda, CA Utility Protection.
- 32. Projects New Orleans Airport, New Orleans, LA Reduce soil pressure
- 33. Projects Arkansas City, Kansas Approach Fill (Bridge Abutments)
- 36. Connector Plates • Galvanized Steel Multi-barbed Connectors • Restrain Rigid Foam from Moving Laterally • Primarily for jobsite safety • 2 Plates for Each 4’ x 8’ Section
