Leak Detection & Repair:
Technology Against Water Loss

A small leak in a pool can mean losing hundreds of liters of water a day, unbalancing chemicals and, worst of all, undermining the ground beneath the structure, causing larger cracks.

At Servinmosol, we don't guess where the leak is: we use advanced technology to locate it with surgical precision, avoiding unnecessary trenches in your garden.

Evaporation or Leak? The Bucket Test

Before you worry, it's normal in summer to lose up to 0.5 cm of water a day to evaporation. To rule it out, we recommend the Bucket Test, a vital first step before calling in the technical team:

• 1

  Fill a bucket with pool water and place it on the first step (partially submerged). Tip: Put a rock inside so it doesn't float away or tip over.

• 2

  Mark the water level both inside the bucket and outside (pool level). Turn off the pump during the test to avoid fluctuations.

• 3

  Wait 24 hours. If the pool level has dropped more than the bucket level, you have a leak. If both levels drop the exact same amount, it's just natural evaporation.

Non-Invasive Detection Technology: Precise Diagnosis

Our differential value is diagnosis. Forget about ripping up all your paving to blindly look for a broken pipe. We have specific equipment to find the fault without breaking anything:

Hydrostatic Pressure Testing

We isolate the pipes (skimmers, jets, main drain) by plugging the outlets in the pool and pressurizing with water or air from the pump house. If the gauge needle drops, we know exactly which pipe is the problem. This lets us rule out healthy circuits in minutes.

Acoustic Geophones & Tracer Gas

Once we know which pipe is leaking, we "listen" to the sound of water escaping under pressure underground using high-sensitivity ultrasonic microphones (Geophones). If the sound is faint, we inject a safe gas (a nitrogen and hydrogen mix) into the pipe that surfaces exactly at the breakpoint, detecting it with an electronic scanner.

Scuba Diving & Dye Testing

If the pipe pressure is fine, the problem is in the structure. Our technicians dive with scuba gear to inspect every inch of the shell, lights, and joints. We use syringes with special fluorescent dyes that are visually sucked into the crack, marking the exact point of the leak.

Common Solutions and Repairs

Once located with pinpoint accuracy, we apply the most durable and least invasive solution possible:

Fitting Repairs (Skimmers, Lights, Jets)

80% of leaks happen here. The joint between the skimmer plastic and the concrete often breaks due to temperature changes and natural ground settling, causing the concrete to give way and lose its watertight seal around these fittings. We repair these joints with high-strength underwater epoxy putties, or replace the fitting entirely if the plastic is cracked.

Skimmer Repair Specialists

This is our number one specialty. We have specific solutions to fix skimmer leaks permanently, reinforcing the structure so it won't give way again.

Structural Leaks (The Pool Shell)

If the crack is in the concrete, simple patching won't work (it will reopen with ground movement). We use high-tension stainless steel staples to structurally "stitch" the crack and prevent it from opening further, subsequently sealing it with cutting-edge elastic and waterproof mortars.

Underground Pipe Breakage

If the leak is underground, our technology allows us to open just a single tile at the exact spot indicated by the geophones, drastically minimizing aesthetic damage to your terrace. We replace the damaged PVC section (usually crushed by roots or settling soil) and repave, leaving the area spotless.
