Pool Leak Detection Lanzarote
Is your swimming pool losing water faster than it should? We specialise in finding leaks in pool shells, buried pipework, and fittings—quickly and accurately, without unnecessary excavation.
Understanding Pool Water Loss in Lanzarote
Swimming pools in Lanzarote face unique challenges. The island’s year-round sunshine, constant trade winds, and low humidity mean pools naturally lose water to evaporation—typically 4-6mm per day during summer months. But when water loss exceeds this, or continues at the same rate overnight when evaporation stops, you almost certainly have a leak.
A pool leak might seem like a minor inconvenience, but the consequences add up quickly. Beyond the wasted water and increased bills, leaking pool water can erode the ground beneath your pool deck, undermine foundations, damage landscaping, and even affect neighbouring properties. The chemicals in pool water can contaminate soil and groundwater. And of course, constantly topping up your pool means constantly adding expensive chemicals to maintain balance.
The good news? Modern leak detection technology means we can find exactly where your pool is leaking without draining the pool, digging up your garden, or causing any damage to your property. Once we’ve pinpointed the leak, repairs are targeted and cost-effective.
Why Pools Lose Water
Understanding the common causes helps us find your leak faster
Evaporation vs. Leaks
In Lanzarote's sunny climate, pools naturally lose 4-6mm of water daily to evaporation. However, if your pool is losing more than this, especially overnight when evaporation slows, you likely have a leak that needs professional detection.
Structural Shell Cracks
Pool shells can develop hairline cracks from ground movement, seismic activity, temperature fluctuations, or simply age. These cracks may be invisible to the naked eye but can lose significant amounts of water daily.
Pipework Deterioration
Underground supply and return pipes are constantly under pressure. Over time, joints can separate, pipes can crack from ground movement, or fittings can corrode, all causing hidden water loss that's impossible to see without specialist equipment.
Fitting & Seal Failures
Every pool has multiple penetrations through the shell, skimmers, return jets, main drains, and lights. Each one has rubber gaskets and seals that deteriorate with age, chlorine exposure, and UV damage.
How We Find Pool Leaks
Professional detection methods for accurate results
Pressure Testing
We isolate each section of pool pipework and apply pressure to identify which lines are leaking. This quickly narrows down the problem area before we pinpoint the exact location.
Dye Testing
Using specially formulated dye near suspected leak points, we can visually confirm where water is escaping. The dye gets drawn into cracks and gaps, revealing leaks in the shell, around fittings, and at tile joints.
Acoustic Detection
Our sensitive hydrophones and ground microphones detect the distinct sound of water escaping from pressurised pipes. Even leaks buried deep underground produce sound signatures we can locate.
CCTV Pipe Inspection
Using specialist pool pipe cameras, we inspect the interior of your pool's pipework. Our VCAM systems include a sonde transmitter that we track from the surface to pinpoint the exact location and depth of internal failures.
Our Pool Leak Detection Process
A systematic approach to finding every leak
Every pool inspection begins with a thorough consultation. We’ll ask about the history of your pool, when you first noticed increased water loss, any visible signs of damage, and your water consumption patterns. This information helps us focus our investigation on the most likely problem areas.
Next, we conduct what’s called a bucket test to confirm leak rates and rule out evaporation. With the pool pump running and then off, we can also determine whether the leak is in the static pool structure or the pressurised pipework system.
Once we’ve confirmed a leak exists and narrowed down the likely source, we deploy our specialist equipment. For pipework leaks, we use pressure testing to isolate the affected line, then acoustic detection or CCTV to find the exact point of failure. For shell leaks, we use dye testing around fittings, joints, and any visible cracks or suspect areas.
Finally, we provide you with a detailed report including photographs, diagrams showing leak locations, and recommendations for repair. We work closely with local pool technicians and can recommend trusted contractors if needed.

Signs Your Pool May Be Leaking
Don’t ignore these warning signs
Constant Top-Ups Required
If you're adding water more than once a week, or your autofill system runs constantly, you likely have a leak.
Wet Areas Around the Pool
Soft, wet, or eroded areas in the ground near your pool, especially when it hasn't rained, indicate underground leaks.
Cracks in Pool Deck
Shifting, cracking, or sinking pool decks and surrounding paving can be caused by water washing away the substrate.
Chemical Imbalance
Constantly struggling to maintain chemical balance? Fresh water dilutes your carefully balanced pool chemistry.
