Our History

Our company has a reputation as a trusted, experienced and reliable provider of commercial concreting services across the North Coast and Northern Rivers regions of New South Wales.  

Founded in 2017, we were one of the key concrete subcontractors involved in the construction of the Clarence Valley Correctional Centre delivered by Infrastructure NSW. Since this first project, we have continued to demonstrate our commitment to high-quality work across some of the largest civil and commercial concrete projects in northern NSW. 


Nat Sewell Concreting (NJS Concreting) is here to serve medium to large commercial builders, property developers and civil contractors. 

From site excavation and preparation, steel fixing, formwork, concrete placement, and finishing, we offer a one-stop shop for our commercial clients – no job is too big or small.
