At Greystone Concrete, strength and consistency are never compromised. We realized over 70 years ago that in order to produce a highly consistent concrete mix, careful internal monitoring and testing are essential. We have 2 fully accredited ACI certified concrete technicians as well as 2 NCDOT concrete inspectors at our operation. They are both vital to insuring overall concrete consistency and proper performance. At all commercial job sites, at least one technician is on hand to carefully monitor the concrete’s slump, air content, and overall concrete performance.
Each of our mix designs is over designed by 1200 P.S.I. in order to give added assurance and extra strength for all jobs. For this reason, our 3000 lb P.S.I. will yield results over 4000 lb. P.S.I. after 28 days. Internal testing is carried out throughout the year to maximize performance at all commercial and DOT jobsites.
