  1. Rigid Foam Anelise Williamson MEEN 3344 11-1-04

  2. Prime Flex 985 • Urethane Resin • Lightweight, rigid foam • Two components

  3. Common Uses: • Slab stabilization from beneath • Filling of Voids in wet areas • Closing up abandoned pipelines or storage tanks.

  4. Benefits of this Material • A relatively fast setting time • Very low viscosity • Can be used in wet situations (retaining wall) • It will bond with the sub soils

  5. Physical Properties at room temperature • Mixing Ratio is (1:1) • Viscosity is 300-450 cps • It takes about 8 minutes to set • Expands at a ratio of 20:1 • A final strength 90 psi (ASTM D-1621)

  6. Installation • Requires open paths for pressure release • This can be minimize by injecting in small shots. • The foam will begin to expand in under a minute.

  7. References • Prime Resins, Inc.
