Precast Wall System (Gravix®)

Manufactured by DECAST Ltd.
Brand: Gravix®

Gravix® precast wall system was created to meet the demand for minimal excavation requirements (~50% of wall height). Being a true gravity system, select fill is not required which allows structural soil fill or various stone or recycled materials to be used as backfill.

The traffic barrier option provides a finished retaining wall with the barrier in place. Gravix® has been tested and successfully passed the MASH TL-4 vehicle impact loading.
