Sunrock: Innovative Thinking in the Concrete Industry

Aside from our commitment to manufacturing a quality product and providing excellent service, Sunrock is also known for innovative thinking in the concrete business.

In 2002, Sunrock was the first concrete company in the U.S. to introduce the twin steer concrete mixer, an innovative delivery vehicle used extensively in Europe and Canada. With two turning axles on the truck, this vehicle is able to transport a full legal 10-yard load of concrete across any roadway. Our fleet of these vehicles enables us to handle weight-restricted roads, thus providing better service and full loads on every delivery.

Strong, more durable concrete

Sunrock is also the only concrete supplier in the Raleigh-Durham market to use manufactured sand in its concrete. This allows for uniform color, consistency and superior finishing characteristics. In addition, our use of manufactured sand and stone as primary ingredients means that Sunrock's concrete makes a harder and ultimately more durable finished product.

At Sunrock, our full-service North Carolina Department of Transportation-approved laboratory is capable of creating concrete that is mixed to meet any job specification or unique application. Sunrock's quality control technicians hold NCDOT, ACI and NRMCA certifications in concrete laboratory field-testing.

Our central dispatch team directs a ready mixed concrete fleet that serves customers across the area from one of our six concrete plant locations in Butner, Durham, Raleigh, Wake Forest, Zebulon and Kittrell. With one point of contact, our dispatch team is the vital link between our customers and Sunrock operations.

What is concrete?

Concrete consists of 85% aggregates (sand and stone) and 15% Portland cement. Cement is produced from the crushing and heating of a variety of rock types, primarily limestone. Cement, the glue that holds aggregates together, is the world’s oldest manufactured building material.

Uses of concrete

Hoover Dam

Because of its ability to be molded into a variety of shapes and sizes, concrete is also one of the world's most versatile building materials. Often reinforced with steel, concrete is used in building foundations, buildings, roadways, bridges, pipe and structural beams. Concrete is also highly recyclable, making it an environmentally sound building material. Reclaimed concrete can be reprocessed into ABC base stone which has a range of uses, most commonly as a road base.
