How to Fix Pool Cracks in Benoni: A Complete Guide for Pool Owners
Swimming pools are a great feature in many homes across Benoni, especially during hot South African summers. However, over time, pools can develop cracks due to age, soil movement, poor construction, or temperature changes. If left untreated, these cracks can lead to water leaks, structural damage, and expensive repairs.
In this guide, we’ll explain how to fix pool cracks in Benoni, what causes them, and the best repair methods to restore your swimming pool safely and effectively.
What Causes Pool Cracks?
Before repairing a crack, it’s important to understand why it occurred. Several factors can cause cracks in swimming pools.
1. Ground Movement
Soil movement and settling are common causes of pool cracks. As the ground shifts, pressure builds against the pool shell, creating stress fractures.
2. Poor Construction
If the pool was not built with proper reinforcement or concrete quality, cracks may appear earlier than expected.
3. Temperature Changes
Extreme heat and cold cycles cause materials to expand and contract, leading to cracks over time.
4. Water Pressure
Pools hold large amounts of water. If drainage or structural support is inadequate, pressure may cause the pool structure to crack.
5. Age and Wear
Older pools naturally develop cracks due to years of use and environmental exposure.
Types of Pool Cracks
Not all cracks are the same. Identifying the type helps determine the correct repair method.
Hairline Cracks
These are thin cracks usually caused by plaster shrinkage or minor surface movement.
Solution: Surface patching or sealant.
Structural Cracks
These are deeper cracks that run through the concrete shell of the pool.
Solution: Professional repair such as epoxy injection or structural reinforcement.
Settlement Cracks
These occur when the ground underneath the pool shifts or sinks.
Solution: Structural repair and stabilization.
How to Fix Pool Cracks in Benoni
Repair methods depend on the severity and location of the crack.
1. Drain the Pool
For major repairs, the pool must be drained to access the damaged area.
2. Clean the Crack
Remove debris, algae, and loose material using a wire brush or grinder to ensure proper bonding.
3. Widen the Crack
Professionals often create a “V” shaped groove along the crack. This helps the repair material adhere properly.
4. Apply Pool Crack Filler
Specialized fillers designed for water structures are used to seal cracks.
Fibre-reinforced pool fillers remain flexible and waterproof, making them ideal for long-term repairs in concrete pools.
5. Smooth and Cure the Surface
After applying the filler, the surface is smoothed and allowed to cure for around 48 hours before refilling the pool.
6. Replaster or Resurface (If Needed)
If the crack damaged the pool finish, resurfacing may be required to restore the appearance and protection.

How to Prevent Pool Cracks
