A small leak in a pool can mean losing hundreds of liters of water daily, unbalancing chemical levels, and worst of all, undermining the ground beneath the structure causing major 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.
Is it Evaporation or a Leak?
Before panicking, losing up to 0.5 cm of water per day due to evaporation in summer is normal. To rule this out, we recommend the Bucket Test, a vital first step before deploying technical teams:
- Fill a bucket with pool water and place it on the first step (partially submerged).
- Mark the water level both inside the bucket and outside (pool level).
- Wait 24 hours. If the pool level has dropped more than the bucket level, you have a leak.
Non-Invasive Detection Technology
Our differential value is diagnosis. We have specific equipment to find the fault without breaking anything:
- Pressure Testing: We isolate the pipes (skimmers, returns, main drain) and pressurize them. If the gauge drops, we know exactly which pipe has the problem.
- Geophones and Trace Gas: We "listen" for the sound of escaping water underground or inject a harmless gas that surfaces exactly at the break point.
- Diving Inspection: We check every inch of the shell, lights, and grout lines with special dyes that are sucked into the crack, marking the exact spot.
Common Solutions and Repairs
Once located, we apply the most durable solution:
Fittings (Skimmers, Lights, Returns)
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 yield and lose its seal around these fittings. We repair these joints with underwater epoxy putties or replace the fitting if it is cracked.
Skimmer Repair Specialists
This is our number one specialty. We have specific solutions to permanently fix skimmer leaks.

If the crack is in the concrete, we use stainless steel staples to "stitch" the crack and prevent it from opening further, sealing it afterwards with flexible and waterproof materials.
Pipe Breakage
If the leak is underground, we only dig at the exact point indicated by our equipment, minimizing aesthetic damage to your terrace. We replace the damaged PVC section (usually caused by roots or settling) and re-pave.
A leak doesn't fix itself; it always gets worse. Escaping water can wash away the soil beneath the pool, causing the shell to settle and crack in half, a breakdown that could cost thousands of euros.
