The Ultrablock system is a green buillding product that is structurally sound, aesthetically appealing, easy-to-install, and an economical solution to replace boulder, timber tie and cast-in-place retaining walls.

As a gravity wall system, Ultrablock units provide the weight and stability to resist applied earth pressures. In addition, vertical or near vertical walls are possible if soil-reinforcing geo-grid is added to the backfill.

A concrete producer in the United States has an average of 1 to 2.5% of "returned concrete" to handle. A plant with a 100,000 yards of annual volume could end up with over 2,000 yards of "returned concrete." This concrete is typically disposed of, potentially creating harmful effects for the environment.

The alternative is to recycle this material, creating a useful post consumer product. U.S. Concrete's Central Concrete, is working to use 100% of their "returned concrete" to produce the Ultrablock LOCK-BLOCK® Retaining Wall System. This "green" building product is available in 18 different shapes and sizes of segmental retaining wall blocks using 100% post consumer recycled concrete material. Together Central Concrete and Ultrablock are creating a winning combination with the environmental future in mind.
