Because a perfect pool starts with knowing how to listen to the water’s signals.
In summer, there’s nothing like diving into your pool after a hot day in Barcelona. But what if one day you notice the water level is shallower than usual? Or that a fine line has appeared in one corner of the pool, like a wrinkle that wasn’t there yesterday? Pool cracks don’t sound a siren. They appear silently, and often too late. Fortunately, there are ways to get ahead of them.
Why do cracks appear in pools?
Structural and environmental factors
Cracks can arise from ground movements, especially in areas like Baix Llobregat or Vallès, where the soil is more sensitive. Temperature changes, heavy rainfall, and the age of the pool also play a role.
Inadequate materials and construction
A poor concrete base, faulty reinforcement, or substandard coating can accelerate the appearance of cracks. That’s why it’s so important to have professionals involved from the start.
Early signs of cracks in your pool
Unexplained water loss
If the water level drops every morning without explanation, there could be a leak. The bucket test can help confirm this.
Visible cracks in the siding
Small lines in tile, paint, or liner may seem harmless, but they could be hiding a larger crack.
Wet or sunken areas around
Your yard can also give you clues. If you notice areas that are consistently wet or have sunken pools near your pool, it’s likely that water is escaping.
Methods for detecting cracks and leaks
Cube Test
Fill a bucket with water and place it on a step. Mark the water level inside and outside the bucket and compare it after 24 hours. If the pool loses more, there may be a leak.
Food colorings
Place a few drops of food coloring near the suspected crack. If the color moves quickly in one direction, there’s a leak.
Professional Inspection
At Piscines Dream, we use advanced detection techniques without emptying the pool. We pinpoint the source of the problem and provide you with the most effective solution.
Consequences of not repairing in time
Major structural damage
A small crack can grow and compromise the entire structure. The sooner you act, the less expensive the repair will be.
Imbalances in water consumption and quality
A constant leak means water loss, chemical imbalance, and increased maintenance costs. Your pool becomes less efficient.
Effective solutions for repairing cracks
Specialized sealants and putties
For small cracks, there are products tailored to the type of coating. Applied correctly, they offer quick and long-lasting solutions.
Professional structural repairs
In more serious cases, it’s best to intervene thoroughly. We repair from the ground up and reinforce weak points to prevent this from happening again.
Prevention and regular maintenance
Periodic inspections
Checking your pool before and after summer is key to anticipating problems. A timely diagnosis prevents future problems.
Maintaining the chemical balance of water
Well-balanced water protects materials. Controlling pH, chlorine, and hardness is also a way to protect the structure.
