Project Summary
- Application: Bridge embankment rebuild
- Scope: Re-enforcement of weak and degraded embankment subgrade
- Product Tensar® Uniaxial Geogrid UX1600
Layfield was called upon for a large amount of Uniaxial Geogrid when the Lower Mainland & Interior of British Columbia (BC) was struck with torrential flooding and numerous severe atmospheric rivers, leaving a trail of damage and destruction. Floods, mudslides, and debris flows are wreaking havoc, destroying several highways, bridges, and arterial roadways. These extraordinary natural disasters caused the BC Government to enact a Provincial State of Emergency, allocating resources to repair and reopen rail and roadways as soon as possible.
Solution
Layfield was approached by a construction company overseeing an urgent bridge rebuild located between the impacted locations of Hope and Merritt, BC. The contractor urgently needed to stabilize the subgrade surrounding a damaged bridge embankment to begin repairs and urgently required a large amount of uniaxial geogrid.
Layfield supplied 40,000m2 of Tensar® Uniaxial UX1600 Geogrid to rebuild the washed-away bridge embankments designed to reinforce soil while resisting elongation (creep). UX1600 uses high-density polyethylene (HDPE) resins designed to resist installation damage while providing long-term high tensile strength. After installation, UX1600 shows no degradation in wet or dry installation environments, perfect for BC’s unpredictable climate and weather events.
Result
With time being a significant factor in this rebuild, Layfield expedited the required materials to the constructor during this emergent situation. The constructor received the materials quickly, helping move the embankment repairs forward faster than anticipated.
