This latest detail from Dave Peterson offers critical guidance when installing steel that bends, but doesn’t break.

As we continue our series of details focused on steel reinforcement for concrete, this detail addresses hooks, bends and offsets that are a part of every watershape's steel curtain(s).

There are always offsets required to jog around skimmers, suction outlets and to purposely keep parallel bars from touching each other (see previous details for non-contact lap splices).

Every bond beam has at least one 90-degree bend if not a full 180-degree hook. Knowing how to arrange steel in those critical structural junctures, is critical in avoiding weak spots in the shell that could be susceptible to cracking over time.

Importantly, there are minimum radiuses required for bends to prevent the steel reinforcement from exceeding its yield strength at the surface. If you bend the bar too tightly it will crack!

This detail helps you determine how to manage those turns while still maintaining structural reinforcement as specified.

[] We recommend electric rebar benders because they can be adjusted to predetermined bend radiuses.[

[] Sometimes we use smaller diameter bars so that we can achieve smaller radiuses - this, of course, needs to be verified against the strength requirements.

10 21 20RLeeimage1Upgrading a tired classic kidney pool should not have been a particularly tall order, or so thought homeowners Kris Anna Andersen and R Lee Steele. Little did they know the depth and complexity they would face in trying to reclaim the pool’s classic beauty and updating its equipment. 

Great work often takes time, says designer/builder, Kevin Cobabe. Case in point, the project pictured here was years in the making with all sorts of hurdles courtesy of the local building department and a tricky site. Through experience and education Cobabe was able to step up and solve the project’s many challenges.

This story is an example of what can happen when preparation meets opportunity. It started way back in 2014, when the client first hired me to build an acrylic fountain at an office building she owns in the Los Angeles area.

She liked the results and asked me get involved at her residence in Rolling Hills, an upscale enclave on the scenic Palos Verdes peninsula overlooking the ocean, where she had a pool that was experiencing

Here, in the second part of a dual project profile, Reid Schindler discusses the sleek, contemporary design he created right next door to a completely rustic, free-form pool he discussed in WaterShapes’ last edition. It's an entirely different (and appropriate) set of design criteria, challenges and solutions.

While some designers are known for a particular style, I’ve always believed it’s far better to be comfortable working across a spectrum of design modalities. Creative bandwidth enables the designer’s ability to focus on the clients’ ideas and desires, as well as the needs of the site itself – and it keeps you from falling into a creative rut.

Case in point:  Last month in Part 1 (click here), I described an unusual

Mark and Zachary Trapani specialize in elevated, above-grade pools, mostly above the concrete canyons of New York City. As they discuss here in the second and final part of this series, it's a niche that requires careful analysis, creativity and sharp eyes for detail -- especially in existing buildings.

b_400_400_16777215_00_images_10-7-20BTSimages_BTS_Logo_865x649.jpgPreventing voids or 'shadows' during shotcrete application is always crucial -- and particularly tricky in designs in which the steel must be close together. In those cases, writes Dave Peterson, consider this detail.

10 7 20DCimageThis time, the folks at Ask the Masters and Pool Pro Podcasts delve into the many reasons why understanding water chemistry and how it can best be managed is beneficial to both watershapers and consumers.

Watershaper Reid Schindler was asked to create side-by-side designs for neighboring business partners. The kicker, he says in the first of a pair of articles, was that the two projects were direct stylistic opposites.

Most watershape designers and builders I know largely rely on referrals to generate new business. That’s certainly been true in my case and I’ve learned that word of mouth is extremely important, and arguably the best form of marketing.

It is unusual, however, to have one referral from a satisfied client turn into two massive projects at the same time. That’s exactly what happened, when one of my past clients

This time, Dave Peterson shares a simple, reliable way to extend stone veneer from the deck surface all the way down into the pool's interior. It's a great way, he suggests, to create a transition from dry to wet surfaces that is durable, graceful -- and visually seamless.

Working with an ample budget, great clients and a large, open canvas all spelled 'opportunity' for Jason Brownlee -- a chance to integrate multiple design elements into a composition in which water, stone, tile and fire define a European look that also offers a dash of mystery.

This project had it all – balance, symmetry, style and luxury on a grand scale, and fantastic clients. More than three years in the making, and recently finished this past spring, the design integrates a number of key principles and modalities with the clients’ desires for elegance, all with a European flare. It was the kind of project that makes you love being a watershape designer.

I’d worked with the pool contractor, Lee Seelig of Waterscapes Backyard Resorts in Nashville, on several past high-end projects. In this case, he was in the early stages
