Redi-Rock in Action: Highway & Bridge Case Studies


Two Projects Saved £16 million

Highways England utilized 2.9 kilometers (1.8 miles) of retaining walls to help upgrade 27.5 kilometers (17 miles) of Highways England road network to Smart Motorways. The installation crew was able to install 75 square meters (800 square feet) per day, resulting in massive savings of over 5.6% of the total budget.

Faster than Cast-in-Place

In this I-75 freeway project, Redi-Rock provided a value engineered alternative for faster construction than cast-in-place walls. The diverging diamond interchange required 16 Redi-Rock walls built using Redi-Rock hollow-core blocks, which use 28% less concrete than solid blocks - reducing transportation costs.
