Sustainable slope stabilization using recycled plastic pins /
"Landslides and slope failure are common in US and rest of the world. The landslides cause significant damage to infrastructure and requires millions of dollars each year to fix the slope. A sustainable and cost effective option can have significant benefits, as it will reduce the maintenance c...
