Case Study

Gordie Howe International Bridge Project

The longest main span of any cable-stayed bridge in North America


Q. What are the benefits of using Alleguard’s Geofoam EPS Blocks for this project?

A: Geofoam is an aesthetically pleasing option for soil fill. For an application like a Bridge and Port of Entry sites, the strength of the product was a major factor where there are unstable grounds.

Q. Why did you choose Geofoam?

A: This innovative product is used to avoid ground settlements under foundation for buildings and excessive loads over buried structures such as city sewers. Instead of building on top of the normal soil and ground, crews replace a large volume of the soil with EPS material, then continue to build on top. As a result, there is no physical load added to the ground and no settlement occurs.
