Introduction
Ever walked by your pool and noticed a faint line creeping along the surface? Maybe it looked harmless at first — but it could be the start of a bigger issue. Cracks in pools are more common than you might think, and ignoring them could cost you thousands. Today, we’re diving deep (pun intended!) into the 7 common underwater pool crack patterns you should patch and why tackling them head-on is your best bet for a long-lasting, leak-free pool.

Why Cracks Appear in Pools
Pool cracks are often silent destroyers. They don’t always show up overnight — instead, they gradually worsen, weakening your pool’s integrity over time.
The Role of Water Pressure
Water exerts tremendous pressure on your pool’s walls and floor. Over time, especially with improper design or installation, this pressure can cause stress cracks.
Temperature Fluctuations
If you live in an area with hot days and cold nights, your pool goes through expansion and contraction cycles. That can lead to surface and structural cracks.
Poor Construction and Materials
Subpar materials or rushed construction can leave your pool vulnerable. Using the wrong patch materials? That’s a recipe for future patch failure.
Dangers of Ignoring Pool Cracks
Letting cracks go unpatched isn’t just an aesthetic issue — it’s a financial one too.
Increased Water Bills
Even small cracks can lead to major water loss. If your water bill is unusually high, you might be dealing with an underwater leak.
Structural Damage
Left untreated, water seeps into the soil around your pool. This can cause shifting, settling, and even total structural failure.
Safety Risks
A sharp edge from a cracked surface isn’t just unpleasant — it’s dangerous. It can lead to cuts or worse, especially for kids and pets.
1. Spider Web Cracks
What They Look Like
Tiny cracks that spread out from a center point — just like a spider web. These often appear in plaster finishes.
Causes and Fixes
They’re usually caused by rapid drying during installation. Fixing them involves resurfacing or applying a bonding patch material. For the right patch material, refer to our patch types and materials guide.
2. Vertical Cracks
Identifying Vertical Cracks
Running straight up and down the pool wall, these cracks can extend deep into the pool shell.
Repair Options
Depending on the severity, repairs may require epoxy injection or applying specialized underwater patching techniques.
3. Horizontal Cracks
Stress Points in Pool Walls
These cracks form due to lateral pressure, often at the waterline or where the wall meets the floor.
Patch Techniques
Apply flexible epoxy or hydraulic cement patches that adapt to minor movement. Learn about proper smoothing techniques via the smoothing tag.
4. Hairline Cracks
Easy to Miss, Hard to Ignore
These thin, surface-level cracks often look innocent. But they let water in — and that’s a big deal.
Long-Term Impacts
They tend to widen with time. Prevent this by adding them to your routine maintenance plan.
5. Corner Cracks
Pressure Buildup Areas
The pool’s corners bear a lot of stress. Cracks here can signal foundational issues.
Best Patch Types to Use
Flexible underwater patches that can mold to sharp angles work best. Explore edge finish and sealing techniques for corner fixes.
6. Floor Cracks
Ground Movement Indicators
When the soil beneath your pool shifts or settles, cracks can form on the pool floor.
Underwater Repair Methods
These require specific underwater techniques. Learn the proper process in our detailed repair section.
7. Bond Beam Cracks
Structural Reinforcement Zones
These cracks often appear in the top structural areas of the pool, compromising its strength.
Permanent Fixes
Use reinforced materials and subscribe to our maintenance updates for ongoing prevention strategies.
How to Inspect and Diagnose Pool Cracks
DIY vs. Professional Diagnosis
You can do a basic dye test, but it’s always wise to bring in the pros. Check out our inspection and diagnosis guide.
Using Pressure Tests
Pressure testing your plumbing can help detect hidden cracks and leaks. Visit our pressure test guide for more.
