If a project needs a lightweight and durable material to resolve a problem with weak foundation soils or slope failures, then tire chips or tire bales are a good choice. We have constructed embankments using tire shreds and repaired slopes with tire bales, demonstrating their use as a lightweight and less expensive fill material.
Tire bales are made of about 100 whole passenger tires. The bales weigh around one ton each and are approximately five feet square and 2-1/2 feet high. With a density between water and soil, engineers consider them lightweight, permeable building blocks.
Research and Demonstrations
Tire Chips or Shreds
Our El Paso District constructed embankments using 1- to 12-inch pieces of scrap tires comparing two methods of construction – homogenous fill and mixed with soil.
