BACKFILL FOR WALLS AND BRIDGE ABUTMENTS

Tire-derived aggregate for use in civil engineering applications can help create a more sustainable future. Tire-derived aggregate is made by reducing scrap tires into shreds as a sustainable and cheaper alternative to conventional lightweight fill. Shreds of six inches and more are used as permeable fill for infrastructure projects.

The performances of retaining walls depend upon the type of backfill. Tire-derived aggregate has 1/3 the weight of soil, drains 10 times better than soil, insulates 8 times better than stone, and costs less than sand and gravel.
