Have you noticed a new crack forming in your backyard oasis? Seeing a fracture in your pool shell can definitely make your heart skip a beat.
David Resurface was founded with a simple mission to provide exceptional pool remodeling services you can truly rely on. We completely understand the stress of discovering a structural issue.
Dealing with aging plaster and concrete problems is incredibly common for pools that hit the 10 to 15-year mark here in the Valley.
You might be wondering if it is just a cosmetic flaw or a sign of a hidden leak.
If you need reliable Pool Crack Repair & Leak Detection, I am going to walk you through the exact steps to figure that out. Grab a cup of coffee, and let’s go through it together.
Why Phoenix Pools Crack
Three main forces crack Valley pools on a regular basis. The constant shifting puts immense pressure on aging plaster and concrete.
- Clay soil movement: The local expansive bentonite clay soil swells heavily during monsoon season and shrinks rapidly during dry months.
- Thermal expansion: Arizona experiences rapid 30°+ temperature swings, often shifting from 110-degree summer afternoons to chilly nights, causing the shell to expand and contract.
- Structural settling: The ground naturally settles and shifts beneath the heavy water load during a pool’s first two to five years.
Our team knows that each of these causes requires a completely different approach to fix.
Crack type matters more than crack size
A hairline cosmetic crack (visible but not through the shell) = injection. A wider structural crack (through the shell, possibly leaking) = injection + stainless staples. Extensive cracking + aged plaster = resurface. We diagnose before we quote.
Our Repair Process
Handling Pool Crack Repair & Leak Detection requires a systematic approach. Every fracture tells a different story about what is happening underground.
Diagnosis first.
We always begin by inspecting the fracture, probing for depth, and checking for obvious signs of water loss. Getting the diagnosis right is the most critical step.
Our technicians run a simple dye test if a leak seems likely. Colored dye placed in the water will visibly migrate directly toward any breach in the shell.
We also perform a pressure test on suspect plumbing lines to rule out underground issues. This comprehensive check ensures you only pay for the exact repair method required.
Injection and Stabilization
Epoxy or polyurethane injection works beautifully for hairline and medium cosmetic cracks. The specialized polyurethane foam we use actually expands up to 25 times its original volume upon contact with moisture.
This incredible expansion allows the material to seep into every tiny fissure and permanently plug the entire thickness of the concrete.
Stainless-steel stapling mechanically ties wider structural cracks closed before any injection happens. Our crew relies on genuine Torque Lock structural staples for this exact reason.
Each of these patented staples applies up to 5,000 pounds of controlled compression across the fracture. This massive holding power guarantees the concrete cannot re-open under future thermal stress.
Sometimes, massive fractures are simply symptoms of widespread shell fatigue. We will recommend escalating to a full resurface if the plaster is failing across the board. Honesty is always the best policy.
Leak Detection
Water loss is a massive concern in Arizona. Normal summer evaporation claims about one-quarter to one-half inch of water every single day.
A true leak requires immediate attention. Losing over one inch per week beyond that normal evaporation rate is a huge red flag.
A tiny quarter-inch leak can actually waste around 378 gallons of water a day, adding up to a surprisingly high utility bill.
You should watch for these common warning signs:
- Visible wet spots or soggy grass around the pool perimeter.
- Equipment that cycles on and off far more often than it should.
- Unexplained spikes of $50 or more on your monthly water bill.
- Air bubbles constantly blowing out of the return jets.
A 24-hour bucket test easily confirms whether the loss is just the desert sun or a genuine breach. You simply place a bucket of water on a pool step, match the water levels, and compare the drop after a full day.
We gladly handle this exact diagnosis on-site to give you complete peace of mind. Finding the source early saves you from dealing with severe structural damage down the road.

Crack Repair & Leak Detection FAQs
How do I know if my pool is leaking?
Water loss over an inch per week (beyond normal evaporation), visible wet spots around the pool perimeter, or unexplained equipment cycling are the three most reliable signs. A 24-hour bucket test confirms vs evaporation.
When is crack injection enough, and when do I need a resurface?
Hairline cosmetic cracks: injection is enough. Structural cracks through the shell: injection + stapling. Extensive surface cracking plus end-of-life plaster: resurface is the smarter spend.
How long does a crack repair last?
Properly injected cracks in a stable shell: 10+ years. Cracks driven by active settling or shifting soil may need escalation to structural repair or pier work.
Do you do underground plumbing leak detection?
We do surface and shell leak detection. For suction-side plumbing leaks we coordinate with a specialist leak-detection company when needed.
Can you repair a leak without draining the pool?
For visible-above-waterline cracks, often yes. Below-waterline cracks require partial or full drain depending on location.
