Beginnings
From mine shafts to subway tunnels, from fountains to swimming pools, shotcrete has long been the preferred material of construction for major projects worldwide.  This process, which involves the spraying of concrete material at a high velocity onto a receiving surface to achieve compaction, offers substantial advantages over alternative approaches with respect to durability, versatility, integrity and sustainability. This has been the case ever since the technique was invented at the turn of the 20th century, yet only now are watershapers - professionals who have made concrete such a crucial part of their livelihoods - truly coming to understand and appreciate shotcrete for what it is. In this three-part series, we'll start with the story of shotcrete's origins - a tale of insight, ingenuity and entrepreneurship.  Then we'll trace

Finding the Cure
As a former shotcrete builder myself, I believe you can't find a better method of building a pool, spa, pond or waterfeature of any type than by using pneumatically placed concrete, or "shotcrete."  The method and the material offer the designer and builder great and often incredible design flexibility, and the resulting watershapes will last several lifetimes. Given that the vast majority of watershapers around the world depend on shotcrete as their primary construction material, it only makes sense that we should know as much as possible about putting this amazing product to its best possible use.  Unfortunately, however, that's not always the case. There's little argument that the process of shotcrete construction is laborious and demanding, that it requires a major logistical and physical effort and that fairly precise timing is necessary.  For all the focus it takes to apply it and shape it just so, however, I have observed a couple of critical steps many builders overlook in the press of getting the job done - the most important of them being the proper curing of the
