Building a Pool in Phoenix? Get the Foundation Right from the Start

Phoenix homeowners love their pools—it’s no surprise, given the year-round sunshine and scorching summer heat. Whether you’re building a custom backyard oasis or a practical pool for family fun, ensuring your investment lasts for decades is a top priority.

But here’s what many first-time pool builders don’t realize: The strength of your pool isn’t just in the concrete—it’s in the steel reinforcement beneath it.

Rebar (reinforcing steel bars) forms the hidden skeleton of every in-ground pool. It prevents cracking, shifting, and structural failure over time, especially in Phoenix’s harsh desert climate. If rebar is improperly installed—or skipped altogether—you could face costly repairs, leaks, or even complete pool failure.

Before you break ground, let’s explore why rebar matters, how it fits into the pool-building process, and why hiring a rebar specialist like Scholz Rebar can save you time, money, and future headaches.

The Phoenix Pool Building Process – What You Need to Know

Building a pool is an exciting but complex process. Whether you’re hiring a pool contractor or subcontracting key parts of the build yourself, understanding each step ensures your pool is built to last.

Here’s a quick breakdown of how pools are constructed:

1. Design & Permitting

2. Excavation

  • A pool contractor digs the shape of the pool according to the engineered design.
  • Phoenix’s caliche soil (hard, compacted layers) can make excavation tricky.

3. Rebar Installation (The Pool’s Skeleton)

  • This is where Scholz Rebar comes in.
  • Steel rebar rods are bent, shaped, and tied together to create the framework.
  • The steel grid provides reinforcement so the pool doesn’t crack or shift over time.

4. Plumbing & Electrical

  • Pipes and wiring for water circulation, lighting, and heating are installed.

5. Shotcrete/Gunite Application

  • Concrete is sprayed over the rebar, forming the structural shell of the pool.
  • Rebar ensures the concrete holds its shape without failing over time.

6. Finishing Touches

  • Tile, coping, and decking are installed.
  • The pool is plastered and filled with water.

7. Final Inspection & Enjoying Your Pool!

  • City inspectors review the build to ensure it meets safety codes.
  • Once approved, your Phoenix pool is ready to use!

Why is Step #3 (Rebar Installation) So Critical?

Without proper rebar, your pool’s concrete will crack over time—especially in Phoenix’s expanding and contracting soil. This leads to leaks, structural failures, and costly repairs.

Keep reading to learn why rebar is non-negotiable—and how hiring a rebar specialist ensures your pool is built to last.

What is Pool Rebar and Why Does It Matter?

Rebar is the hidden framework that gives your pool the strength to withstand decades of use. While concrete is incredibly strong under compression, it is prone to cracking under tension. This is where rebar comes in—by reinforcing the concrete shell, it prevents structural failure, shifting, and long-term damage.

In Phoenix, where high summer temperatures cause soil expansion and contraction, rebar is even more crucial. Without it, your pool shell is at risk of developing cracks that lead to water leaks, costly repairs, or, in extreme cases, complete structural failure.

How Rebar Strengthens a Pool

  • Prevents cracking – Helps absorb tension forces that would otherwise cause fractures in the concrete.
  • Increases durability – Ensures the pool structure can withstand ground movement and temperature shifts.
  • Supports weight loads – Reinforced concrete can hold the pressure of thousands of gallons of water without shifting.

During installation, rebar is placed in a grid-like pattern and tied together to create a cage. This framework follows the engineered design and provides even structural support throughout the pool shell.

If rebar is installed incorrectly—such as being spaced too far apart or not properly secured—it can create weak points that may not show up immediately but will lead to major problems down the road.

What Happens If You Skip Professional Rebar Installation?

Cutting corners on rebar placement is one of the biggest mistakes you can make when building a pool. Even a minor miscalculation in spacing or depth can lead to long-term structural failures.

Some common mistakes include:

  • Improper spacing – If rebar is too far apart, it won’t provide enough reinforcement, leading to weak spots in the pool shell.
  • Placing rebar too close to the surface – This can cause rusting, which weakens the structure over time.
  • Using low-quality or thin rebar – Inferior materials reduce the overall strength and longevity of the pool.

These errors often result in pool shell cracks, water leaks, and costly structural repairs. Fixing these problems can be significantly more expensive than getting the job done right the first time with a professional rebar contractor.

For Phoenix homeowners, investing in expert rebar installation ensures their pool is built to withstand the desert’s harsh climate and remain in excellent condition for years to come.

Should You Hire a Pool Builder or Subcontract Your Own Rebar Work?

When building a pool, homeowners typically have two options: hire a general pool contractor who manages the entire project or take a more hands-on approach by subcontracting specialized tasks like rebar installation themselves.

If you’re looking to save money and ensure quality craftsmanship, subcontracting rebar installation to a specialist like Scholz Rebar can be a smart move.

Hiring a General Pool Contractor

A general pool builder oversees the entire project, from excavation to finishing. While this can simplify the process, many pool companies subcontract the rebar phase to third-party specialists anyway. Unfortunately, some contractors cut costs by hiring the lowest bidder, which can lead to inferior materials, rushed work, or improper rebar placement.

If you want to ensure that your pool’s structural foundation is rock solid, it makes sense to hire a trusted rebar specialist directly.
