Trader Joe’s Case Study

A revolutionary advancement to masonry construction, the RainBloc Integral Water Repellent System is a patented additive incorporated in the Concrete Masonry Unit (CMU) and is factory blended in the Amerimix Water Repellent Mortar. This high-performance, polymeric-based water-repellent admixture resists wind-driven rain, mold, mildew, and efflorescence staining. RainBloc has been proven to have no impact on the bond strength and board life of the mortar, making it perform no different than current mortars.

On past projects, Ammex Masonry mixed RainBloc into the mortar on site, which proved to be difficult and time-consuming. By switching to Amerimix Water Repellent Mortar with RainBloc, Ammex Masonry was able to quickly make consistent batches every time. The time savings enabled Ammex Masonry to complete the Trader Joe’s construction on schedule. The mason has been extremely satisfied with the Amerimix products, especially the workability, ease of troweling and secure attachment to the head/vertical joints.

Ammex Masonry used Amerimix silos to help the job run efficiently and on schedule. Masons simply had to pull
the silo handle to drop material into the mixer and then add water. The silos allowed masons to make a batch of mortar in half the time of conventional mixing, increasing productivity. The silos also eliminated labor expenses associated with bag handling, loading, and sand shoveling. Plus, silos were easy to move around the job site and kept products dry due to their weather resistance.

Just as Trader Joe’s has proven itself successful in the grocery industry, Amerimix Core Fill Grout and Amerimix Water Repellent Mortar with RainBloc have proven successful in building a water-resistant wall system. As a testament to its effectiveness, all Colorado Trader Joe’s have been constructed using Amerimix products.
