If you own a swimming pool, one of the most concerning issues you may encounter is a pool pipe leak under concrete. It can be frustrating, especially when the leak is not visible but is causing water loss and structural damage. Fortunately, fixing a pool pipe leak under concrete is not only possible but also efficient when handled with the right approach and advanced technology.

At Showtime Pools, we specialize in pool leak detection and repair, proudly serving Toronto, GTA, York Region, Durham Region (including Oshawa, Whitby, Pickering, Uxbridge, and Ajax), Simcoe County, Peel Region, and Muskoka.

This blog explains how professionals locate and fix pool pipe leaks under concrete, what signs to watch for, and how homeowners can protect their pools from long-term damage.

Understanding the Challenge: What Is a Pool Pipe Leak Under Concrete?

A pool pipe leak under concrete refers to water escaping from one of the underground plumbing lines that run beneath your pool deck, patio, or surrounding hardscape. These pipes typically carry water between the pool, pump, filter, and heater. Because the leak is hidden under a solid surface, it’s not visible and can cause damage over time if not promptly repaired.

Leaks under concrete can waste thousands of liters of water per week and create soil erosion, which in turn can lead to cracking in the pool deck, shifting tiles, or sinking concrete slabs. A timely response is critical.

Signs You May Have a Pool Pipe Leak Under Concrete

Here are some common indicators that may suggest a pool pipe leak is hiding beneath your concrete:

If you notice one or more of these issues, it’s time to consider professional leak detection services.

How Is a Pool Pipe Leak Under Concrete Diagnosed?

Many pool owners wonder if detecting an underground leak means tearing up the entire deck. Fortunately, with modern technology, we no longer rely on guesswork. At Showtime Pools, our team uses non-invasive methods and tools to locate the precise location of a pool pipe leak under concrete.

Here are some of the advanced techniques we use:

1. Pressure Testing

This method involves isolating individual plumbing lines and testing their pressure to see if they are holding properly. A drop in pressure confirms a leak in the system.

2. Electronic Listening Devices

Using acoustic sensors, we listen for the sound of escaping water through the concrete. Even a pinhole leak can produce distinct sound frequencies that can be pinpointed accurately.

3. Helium Detection

In some cases, helium gas is injected into the plumbing lines. As the gas escapes through the leak, specialized sniffers detect its location at the surface.

4. Thermal Imaging

Infrared cameras can detect temperature changes in the ground caused by leaking water. This method is especially useful when concrete surfaces are large or complex.

These tools allow for precise detection of the leak location with minimal disruption, ensuring the problem is addressed without unnecessary excavation.

How Can a Pool Pipe Leak Under Concrete Be Repaired?

Repairing a pool pipe leak under concrete involves two key phases: targeted access and pipe repair. Once the leak is located, we focus only on the affected area, cutting a small section of concrete for access.

Here’s what the repair process typically involves:

Step 1: Concrete Removal

We use saw cutting equipment to neatly remove only the required portion of the concrete deck or patio. This reduces mess and minimizes repair costs.

Step 2: Leak Exposure

After removal of concrete and some soil, the leaking pipe is exposed. The area is cleaned and dried to prepare for the repair.

Step 3: Pipe Repair or Replacement

Depending on the damage, the section of the pipe is either repaired with couplings or replaced entirely. High-pressure fittings ensure durability and water-tight seals.

Step 4: Soil Compaction and Surface Restoration

Once repaired, the soil is compacted to prevent future settling. The concrete surface is then re-poured and finished to match the surrounding area.

This efficient approach reduces downtime, limits damage, and ensures a long-lasting solution.

Preventing Future Pool Leaks

Once a pool pipe leak under concrete has been fixed, homeowners often ask how to prevent it from happening again. Here are some expert recommendations from Showtime Pools:

1. Schedule annual inspections to monitor pressure in the plumbing system.

2. Winterize your pool properly to avoid freeze-thaw damage in buried pipes.

3. Avoid planting deep-root trees near the pool as roots can shift and damage underground plumbing.

4. Monitor chemical levels regularly as aggressive water chemistry can corrode pipes over time.

5. Install water level sensors to receive early alerts when abnormal drops occur.

Taking these preventive measures can extend the life of your pool plumbing and save you from future expensive repairs.
