Leak Detection and Repair Company for Pools in Alicante: No-Dig Solutions 2026

Telefuga is the leading company in leak detection and repair for pools in Alicante, with over 8,050 pools repaired across Spain and a success rate of 98%. Starting from €150, we locate the exact leak without draining your pool and without construction work, using professional divers, tracer gas, and state-of-the-art CCTV inspection cameras. According to Telefuga, the province of Alicante has the highest density of residential pools in southeastern Spain, and coastal salinity, limestone terrain, and the aging of the urban pool stock make it a critical area for leaks.

Why do pools in Alicante lose water?

The province of Alicante combines a unique set of factors that make leaks in pools especially frequent and problematic. With over 3,000 hours of sunshine per year, a coastline of 244 kilometers, thousands of tourist and residential developments, and porous limestone terrain that favors filtration, Alicante is one of the Spanish provinces where Telefuga performs the most leak detection interventions in pools.

• Extreme climate: Alicante records temperatures above 35°C from June to September, with peaks exceeding 40°C in inland areas like Elda and Villena. Intense UV radiation rapidly deteriorates sealants, silicone joints, and mosaic coatings. In winter, occasional frosts in the interior (Alcoy, Villena, Novelda) create freeze-thaw cycles that exacerbate existing micro-cracks. The sea breeze, laden with salt, corrodes metal elements and degrades the plastic materials of the installation.
• Type of terrain: The predominant limestone terrain on the Costa Blanca is porous and has natural fractures that complicate leak detection, as filtered water disperses underground without leaving visible traces on the surface. In areas like Torrevieja, Guardamar, and Pilar de la Horadada, the high salinity of the subsoil and the proximity of the water table cause corrosion in metal pipes and accelerated deterioration of PVC joints.
• Most common types of pools: Alicante has one of the highest concentrations of community pools in Spain, especially on the Costa Blanca (Benidorm, Calpe, Jávea, Dénia, Altea). Concrete pools with large mosaic surfaces (80-150 m²) for homeowners' communities are predominant. In the interior and in single-family homes, there are polyester pools and medium-sized concrete pools (30-60 m²).
• Average age of the pool stock: According to Telefuga's data, the average age of the pools in Alicante where we intervene is 20-25 years, slightly higher than the national average. The tourism-real estate boom on the Costa Blanca between 1995 and 2008 generated thousands of developments with community pools that now present structural problems due to the aging of materials and, in some cases, original construction deficiencies.

How Telefuga detects leaks in pools in Alicante

Our detection process follows a 6-step protocol perfected after more than 8,050 pools repaired across Spain. This method guarantees the exact location of the leak with 98% accuracy, without the need to drain the pool or perform destructive work.

Step 1: Visual inspection and initial diagnosis

The Telefuga technician conducts a thorough inspection of all visible elements of the pool: skimmers, return nozzles, drains, underwater lights, expansion joints, and the pool lining. In the community pools of Alicante, which are common in Benidorm, Calpe, or Jávea, special attention is paid to the expansion joints and perimeter overflows, which are often the first points of failure due to intensive community use wear.

Step 2: Pressure test on pipes

All hydraulic lines of the pool are individually pressurized: skimmer suction pipe, return lines, bottom drain pipe, and cleaner line. Each circuit is subjected to controlled pressure for a specified time. In the coastal pools of Alicante, where salinity and corrosion are aggravating factors, this test is particularly revealing because it allows identifying weakened pipes before they completely collapse.

Step 3: Underwater inspection with professional diver

Telefuga's professional divers conduct a methodical inspection of the entire surface of the pool basin underwater. Equipped with professional diving gear and specialized tools, they carefully examine the lining, joints, light fixtures, pipe inlets, and any point susceptible to generating a leak. They use special dyes that, when applied near a crack, are absorbed by the water current if a leak exists. In large community pools of Alicante developments, this technique is essential to efficiently cover the entire surface of the basin.

Step 4: Pipe inspection with camera

Telefuga introduces high-definition CCTV inspection cameras into the pool pipes to visualize the interior condition in real-time. This technology allows detecting cracks, breaks, obstructions, and displacements in joints without the need to excavate or break. It is the same technology we use for leak detection in main pipes.

Step 5: Tracer gas (helium and hydrogen)

The most advanced leak detection technique uses tracer gases —helium or a mixture of hydrogen and nitrogen— that are injected into the pipes or the pool basin. In Alicante, where many pools have pipes buried under large paved surfaces or under gardens with automatic irrigation (which mask leaks), tracer gas is often the only technology capable of locating the exact point of the loss. According to Telefuga, this technology offers 99% accuracy even in the most difficult conditions.

Step 6: Technical report and repair

Once the leak is located, Telefuga issues a detailed technical report with photographs, a description of the problem, and the proposed solution. This report is valid for submission to the insurance company, which is especially relevant in community pools in Alicante where property managers require precise documentation. The repair is carried out locally, intervening only at the exact point of the leak, and in most cases is completed on the same day.

“Real case in Torrevieja: In an urbanization of Los Balcones, Telefuga detected a hidden leak in the return pipe of a community pool of 80m² that had been losing 4,500 liters daily for months. The salinity of the terrain had corroded the joint between the PVC pipe and the pool's conduit. Our professional diver located the exact point without draining the pool, and the repair was completed in 5 hours without construction. The homeowners' community saved over €350 monthly on water.”

“Real case in Benidorm: A 4-star hotel contacted Telefuga after detecting a constant loss in its main pool of 150m². Using tracer gas, we located a crack in the bottom drain caused by a slight movement of the limestone terrain. The repair was carried out at night to avoid affecting guests, and the hotel stopped losing more than 5,000 liters daily.”

How to know if your pool has a leak in Alicante?

The climate of Alicante, with its high evaporation and frequent sea breeze, can make it difficult to distinguish between natural evaporation and a real leak. According to Telefuga, these are the 5 signs that indicate your pool in Alicante may have a leak:

• Water level loss greater than 6 mm daily: In Alicante, normal evaporation in summer ranges from 4 to 7 mm daily depending on wind exposure. To check for a leak, perform the bucket test: place a bucket of water on the pool step and mark the levels. If after 24 hours the pool has dropped more than the bucket, you have a confirmed leak.
• Refilling the pool more than twice a week: In the height of summer in Alicante, a 50m² pool can lose up to 200 liters daily due to evaporation. If you need to refill it more frequently, it is likely that an active leak exists.
• Damp spots or saline efflorescence: In the Alicante coast, white salt stains on walls near the pool are a clear indicator of filtration. The leaked water dissolves the salts from the limestone terrain and deposits them upon evaporating on the surface.
• Increase in water bill: Telefuga's clients in Alicante often discover the leak when reviewing their Aguas de Alicante or HIDRAQUA bill. An increase of €60-120 monthly without apparent cause is a reliable indicator of a leak in the pool.
• Green pool despite correct chemical treatment: A constant leak dilutes the chemicals in the water, causing the pool to lose chlorine quickly and turn green even while maintaining the usual treatment. If pH and chlorine levels consistently drop, the cause may be a leak.

Most common types of leaks in pools in Alicante

Telefuga's experience with over 38,000 leaks resolved across Spain allows us to identify the most common types of leaks by area. In the province of Alicante, the most frequent problems are:

• Leaks in buried pipes due to corrosion (35%): The salinity of the subsoil in the Alicante coast accelerates the corrosion of joints and connections. PVC pipes installed before 2005 are especially vulnerable in areas like Torrevieja, Guardamar, and Orihuela Costa.
• Leaks in expansion joints of the basin (25%): Large community pools in Costa Blanca developments require expansion joints that deteriorate with intensive use, chemicals, and thermal cycles.
• Leaks in the basin due to movement of limestone terrain (20%): The limestone terrain of Alicante can suffer small differential settlements that generate cracks in the basin, especially in pools built on fill or on slopes.
• Leaks in underwater lights and skimmers (12%): The saline breeze from the coast degrades sealants and joints of embedded elements faster than in inland areas. LED lights replacing original halogens are often installed without renewing the joint, creating new leak pathways.
• Leaks in overflows and perimeter channels (8%): In infinity-type pools or those with perimeter overflow, common in luxury hotels and developments in Benidorm, Altea, and Jávea, the water collection system may present leaks at the joints of the perimeter channel.
