Recent heavy rains caused a landslide on the highway that connects Spring City in Rhea County to Crossville in Cumberland County. The subsequent detour around the affected area adds up to two (2) extra hours to local residents’ commute. GeoStabilization International® arrived on-site within 48 hours to begin emergency repairs that are expected to take four (4) weeks to complete. After loose material is removed from the slide area, soil nails and shotcrete will be utilized to stabilize the remaining slope. Then a Geosynthetically Confined Soil® (GCS®) wall will be erected to reclaim the lost roadway. More details are contained in this News Channel 9 story.
When a portion of Sunset Road on Vashon Island in King County experienced a landslide with previous surficial erosion issues, GeoStabilization International ® provided a design/build/warranty solution. To restore the approximately 70-foot length of damaged road, GSI installed an array of SuperNails ™ to stabilize the slope and faced it with galvanized high-strength mesh.
