Fly Ash for Hire
Each year, roughly 15 million tons of ash created by U.S. coal-fired powerplants is recycled. Most is used in concrete and other construction materials, such as structural fill, but utilities,...
Manhole Rehabilitation
Manholes are frequently the forgotten element in infrastructure renewal. When they aren't properly maintained they allow excess water into the sewer system, and structural...
Putting It Back
Before construction of the largest inclined turbines in the U.S., the Santa Ana River would carry storm flows out to sea, lost to the residents of water-poor Orange County. The area's...
