This case study highlights how ProMatrix® EFM helped revegetate a 2:1 pipeline right-of-way near Kitimat, British Columbia. Coastal GasLink Pipeline, Skeena Sawmills and their contractors needed erosion control that met strict environmental and safety standards while stabilizing steep slopes. After soil testing, MALT Ventures hydraulically applied fertilizer 18-24-12, North West General Mix seed and ProMatrix Engineered Fiber Matrix® at 3,900 kg/ha (3,500 lb/ac). The engineered fiber matrix held seed and soil in place for germination, combining quick vegetative establishment with lasting performance. Six months after application, follow-up visits showed lush cover, strong root systems and results that exceeded project requirements.
Key Points
- Challenge was to revegetate a 2:1 sloped pipeline right-of-way while meeting strict environmental and safety standards.
- Soil tests showed aggregate soil from 15-centimeter rock to fine particles with limited organic matter, guiding fertilizer and seed selection.
- MALT Ventures hydraulically applied fertilizer 18-24-12 at 400 kg/ha (350 lb/ac), North West General Mix seed and ProMatrix at 3,900 kg/ha (3,500 lb/ac) without placing workers on steep slopes.
- ProMatrix held seed, fertilizer and soil in place, producing lush vegetation and strong root systems within six months and exceeding environmental and safety standards.
