They have been using the stuff quite a lot recently in Vancouver in new waterfront parks. Much of Vancouver's waterfront is, at least partially, fill. Large tracts were deposited by the Canadian Pacific Railway when they gradually filled in the edges of a waterbody called False Creek to expand their railyards and the land they had available to lease to industry. The new parks that have been built above this century-old fill rely heavily on this geofoam to allow for naturalistic rolling terrain and terracing without the associated weight.

In areas of the city with a high watertable due to the Fraser River geofoam is an attractive alternative to costly and time consuming pre-loading areas that will only be landscaped.

Lastly, our new convention centre has an immense 6 acre green roof and a fair number of 'green slopes' above the exhibition hall and parking garage. Geofoam was used extensively both as an insulator on the roof and for mass on the green slopes connecting to the adjacent park.
