Western Interlock Manufacturing Rickreall

Concrete interlocking paving stones and modular retaining wall units are made from Portland cement, coarse and fine aggregates, and water. Iron oxide pigments are 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 then conveyed into a machine which then dispenses a portion of the mix through a feed drawer into the mold. Watch a video of the process here

The concrete in the mold is compressed with thousands of pounds per square inch and vibrated at a high frequency. The resulting paving stones or retaining wall blocks retain their shape as the mold is stripped from them. The product is set aside to cure for a minimum of 24 hours. After the stones are sorted for defects and packaged on pallets, they are ready for shipment.
