. Geofoam and Lightweight Fill

Columbia Green has recently expanded our options for lightweight rooftop structural fill and insulation. See below for solutions for lifting elements or creating mounding on the rooftop in a lightweight, low cost way. Explore your range of options or contact us to discuss.


EPS GEOFOAM

Columbia Green Geofoam is made from expanded polystyrene and used for lightweight structural fill on rooftops.  Ideal for landscaping applications, especially on projects with weight restrictions. 

Our Geofoam is used to fill planter bottoms, create landscape mounding or to lift and align rooftop surfaces like pedestals or green roof trays with a product that is 100 times lighter than soil.   It is a great way to fill large areas without requiring compaction with a lower global warming potential than other foam options. Available as blocks, sheets, tapers or custom sizes, or can be cut in the field.
