Expanded polystyrene (EPS) Geofoam has been used as a geotechnical material since the 1960s. EPS Geofoam is approximately 1% the weight of soil and less than 10% the weight of other lightweight fill alternatives. As a lightweight fill, EPS Geofoam reduces the loads imposed on adjacent and underlying soils and structures.
Sitka Alaska has found a solution to an ever present engineering challenge. It’s not just another tool in the tool box, it is the tool… EPS Geofoam. The Geofoam solution has made the reconstruction of Sitka’s Moller Field, the “Field of Dreams”. Dating back to the 50’s, it was considered the premier baseball field of Southeast Alaska. Over its history it became a horrible marsh due to the deep poor soils it was built on. Today it is the only all-turf field in Alaska.
The field’s reconstructionsuccess was due in large part to Geofoam. Geofoams’ use reduced the overall weight of the field and gave rigidity to the otherwise waterbed like third class field that it was. Today it is the field the rest of the state wished it had.
