Concrete interlocking paving stones and modular retaining wall units are made from Portland cement, coarse and fine aggregate, and water. Iron oxide pigment is used to add color. The ingredients are combined in a mixer, along with admix (an additive used to boost strength and reduce efflorescence), and a small amount of water. The concrete mixture is dumped into a machine which then dispenses a portion of the mix through a feed drawer into the mold.

The product is set aside to cure for minimum of 24 hours. After the stones are sorted for defects and packaged on pallets, they are ready for shipment.
