A Modern Solution For Age-Old Problems

Expanded polystyrene (EPS) geofoam has been used throughout the world for over 30 years in applications where ultra-lightweight fill material has been specified for:

  • Site development on poor load-bearing foundation soils
  • Reduction of lateral pressure on vertical walls
  • Stress reduction on underground structures and/or utilities
  • Temperature control and/or frost protection

STYRO-FLEX EPS Geofoam provides cost-effective solutions where conventional construction methods have failed or shown sub-standard performance. Unlike traditional engineering and construction practices that work to resist the forces of nature, geofoam is designed to work with them. Geofoam's success derives from the fact that it is often more cost-effective to reduce the forces acting on a structure or foundation soil than it is to reinforce them to withstand the forces that would exist without geofoam substitution.

EPS Geofoam Advantages

  • Ultra-Lightweight EPS: geofoam weighs only 1.00-2.00 lb/ft3, approximately 1% the density of soil or rock.
  • Reduced Construction Times: EPS geofoam construction is very fast, particularly beneficial with compressed project timelines.
  • Predictable Material Behavior: EPS geofoam is an engineered product, unlike other lightweight fill materials that can be variable in composition.
  • Non-Biodegradable: EPS geofoam physical properties will not degrade, assuring long-term performance in engineered geotechnical applications.
  • Inert: EPS geofoam will not leach into surrounding soils or groundwater and provides no nutritive value for plants or animals.

Geofoam Applications

STYRO-FLEX EPS Geofoam is a versatile material that provides innovative solutions to many common, and not so common, geotechnical challenges. A cost-effective alternative to traditional construction practices, EPS geofoam has documented benefits in the following applications:

  • Road Embankments
  • Bridge Approach Fill
  • Slope Stabilization
  • Earth Retaining Structures
  • Plaza Decks
  • Structural Foundations
  • Compressible Inclusions
  • Dikes/Berms/Levees
  • Landscape Fill
  • Insulation/Frost Protection

Note: Other engineered applications may also be appropriate for STYRO-FLEX EPS Geofoam.

University of Minnesota Minneapolis, Minnesota

Riverbend Commons, at the University of Minnesota, reclaimed its view of the Mississippi River by replacing an above-ground parking ramp with an underground structure. Concerned over the stress that landscape soils would impose on the structure, engineers significantly reduced structural loads by specifying geofoam to create their landscape.

County Highway 12
Elk River, Minnesota


Constructed over peat deposits 22'-28' deep, County Highway 12 experienced severe settlement even after previous attempts to correct the problem were made. With minimal excavation, a geofoam road embankment was constructed to reduce the overburden on the underlying poor soils.

County Highway A
Bayfield, Wisconsin


For over 20 years, County Highway A had a history of slope failures, and conventional remedies had failed to correct the problem. Geofoam enabled engineers to reduce the landslide driving force without lowering the grade at the head of the slide.
