Lemmen Holton Cancer Pavilion was designed with large planters that were approximately 3’ deep and several feet in width and length on the interior of each of the 3 floors and the attached parking structure. When Foilage Design, the interior landscapers, came on the project, enough changes had been made to the building’s structure that it could no longer support the soil, aggregate and plants to fill these large planters . They chose Elevation® Geofoam to fill the planters about 75% of the way and then used just enough soil on top to support plant life. The larger trees were placed in the foam after carving out a space for the root ball and adding root inhibitor.
By using 212 CUYDS of EPS22, the overall weight of the planters was reduced by 676,219 lbs, or 338 tons, as Elevation Geofoam weights about 1-3 lbs/CUFT versus soil at 100-120 lbs/CUFT. EPS22 was chosen as the material grade based upon the loading exerted on the foam during the installation of some of the larger plants and trees. Other landscaping projects have relied upon EPS15 -39 depending upon the load requirements of the specific project.
Some people do not see Geofoam as being a green building material, while others disagree. It is a non biodegradable material, which means it requires no maintenance or replacement during the life of the project, i.e. less energy, time, money, and no landfill. Since Geofoam is non biodegradable, it can be reused in its original form at the end of the projects life. Conservation and reuse of materials in their original form is the most responsible use of building materials. There have been cases in both Europe and the US of Geofoam blocks being reused from demolition projects on new construction.
