reinforcing steel
Cast-in-place coping can be used to create a wonderful, clean-looking edge treatments, but like all construction details on pools and other structures that hold water, what you don’t know can lead to problems. In this case, it might come as a surprise to some that “doing it right” means leaving out the steel.

Preventing voids, or "shadows" during the shotcrete application process is crucial, says Dave Peterson, and it's particularly tricky in designs with steel close together. In those cases, he says, use this detail.
It happens more often than it should: Even in times when trade shows and educational enterprises such as Genesis 3 all stress the importance of knowing the basic forces at work within and around pool shells, I am all too often called in to investigate cases in which a builder has made a large and careless mistake that can have disastrous consequences. The point these contractors are overlooking is that the bond beams of many (if not most) pool shells are engineered in such a way that
Some clients don’t know any limits when it comes to their ambitions – and that’s certainly been true in this case. His mountain-sized home is set on a relatively flat four-acre parcel in otherwise hilly Ramona, Calif. The client himself describes the building as looking like a casino, and indeed it does have a decidedly “eclectic” architectural look. What he wanted was a backyard to match – a free-wheeling composition that might best be described as a Tommy Bahama-inspired tropical resort. He let me know that the family
Watershapes come in lots of configurations and sizes, but when you get right down to it, they mostly share two basic materials of construction - concrete and steel - that in combination have the potential to withstand generations of use. Fashioning these structures is at the heart of what watershapers do: Every-thing else, from the plumbing or the plaster to the tile or the decking, is really secondary. Sure, the pool won't function without plumbing or look pretty without tile, but it wouldn't even exist without its skeleton of steel and its concrete flesh. For all that importance, however, most people tend to give the steel in particular little thought or care. It's invisible once the gunite is in place, so there's a tendency even among those who know better to blow it off and save a few bucks by using too little steel or by doing quick, sloppy work. And why should you care? No one will ever see what you've done, right? Actually, given the role that steel plays in the durability and viability of the concrete structure, this should be the last place to
