A major roadway repair project completed in just two weeks using geosynthetics has won the IGS Corporate Case Study competition for the IGS Americas region.
Critical work was needed after an elevated section of Interstate 95 near northeast Philadelphia in the United States collapsed on June 11, last year, after a fuel tanker crashed onto the road below, killing its driver. The crash weakened the steel beams supporting the bridge, causing it to collapse.

Aggregates made from recycled glass and polymeric geosynthetic reinforcements were used to repair the affected section, including HUESKER North America’s Fortrac T high tenacity polyester geogrid. HUESKER’s Vona Ojaruega presented the case study, ‘I-95 bridge collapse emergency repair in Philadelphia: geogrid reinforced recycled glass aggregate wall constructed in 12 days’, at the regional finals held at the recent GeoAmericas 2024 event in Toronto, Canada.
Also competing were:
- Solmax, presented by Drew Loizeaux, on ‘Utilizing multiple geosynthetic solutions to provide long-term, cost-effective channel stabilization in British Colombia’.
- Maccaferri, presented by Petrucio Santos, on ‘Closure of the ash landfill at the Punta Catalina thermoelectric power plant, Dominican Republic’.
The session was chaired by IGS Corporate Committee chair Francesco Fontana, with judges IGS Treasurer Jie Han, General Secretary of IGS Brazil Natalia de Souza Correia, and senior mining environment engineer with AtkinsRéalis in Quebec, Canada, Sandra Pouliot.
HUESKER’s winning case study will join other regional winners in the grand final at the 13th International Conference on Geosynthetics in Montreal, Canada, in 2026.
