South Lake Union Repair Project

If you live or work around South Lake Union, and if you utilize the park at the North end of the lake, you have likely noticed some major renovations happening. I have been mesmerized by the big white hunks of foam visible from my office, and had to take a trip closer to investigate. I  marveled at the apparent strength of the construction workers who were able to lift a block the size of a small home with little effort. As I watched them work I did a little research on Geofoam, and found it fascinating enough to share, because certainly anyone who has seen the stuff, has surely been at least a little curious. Geofoam is a lightweight fill material often used as a soil replacement in projects where erosion and shifting become issues.

Geofoam applications include:

Transportation

  • Highways and Roads
  • Railways
  • Airport Runways
  • Ramps
  • Bridge Approaches
  • Retaining Walls
  • and so many more..

Geofoam Advantages over other Fill Materials

  • Lightweight – Minimize preloading, surcharging and staged construction
  • Weather Resistant – Withstands freeze-thaw cycles, moisture and road salts,
  • Doesn’t Settle – Less structural inconsistencies
  • Insect and Mold Resistant – Will not sustain mold or mildew growth, termite / ant repellant additive available
  • Manufactured to Meet Your Job Specifications – Multiple densities, various block sizes available
  • Ease of Installation – Lightweight, no heavy equipment needed, cuts easily with a hot wire or saw
  • Environmentally Friendly – 100% Recyclable, No HCFCs or Formaldehyde

The following is a bit about the project and it’s expected completion date.
