Ace Hardware and Sakrete are some retailers that sell concrete. The Home Depot is also a retailer that sells various types of premixed concrete and cement.
Ace Hardware offers ready-to-use concrete mix in 10-pound packages. Sakrete offers concrete mixes for various purposes including footings, poles, countertops and walkways. Sakrete provides high-strength concrete mix for structures that require high compressive strengths. It also offers high-yield concrete suitable for buyers who want to reduce the number of bags needed to finish a job.
The Home Depot offers anchoring premixed concrete that is stronger than regular concrete. It also offers fiber-reinforced premixed concrete for the reduction of cracking and flaking. This type of concrete removes the need for wire mesh in some applications.
