Leak Detection Lanzarote: Underground Pipe & Cable Detection

Underground detection is the process of locating buried utilities, pipes, and cables without digging. The goal is to produce an accurate picture of what lies beneath the surface before any excavation, drilling, or repair work takes place.

This matters enormously in Lanzarote. The island's volcanic basalt rock is exceptionally hard and costly to break through, so unnecessary digging is expensive and time-consuming. An accurate underground survey means you only excavate where you need to.

Our underground surveys are used by a wide range of clients across the island.

Homeowners and villa owners who suspect a leak beneath a terrace, garden, or pool surround - where water is escaping but no visible signs point to a source above ground.

Builders and construction teams who need to know what utilities are buried on a site before groundwork begins, to avoid cutting through water mains or electrical cables.

Property managers and community presidents overseeing shared utility networks across urbanisations and apartment complexes, where buried pipe routes are unknown or poorly documented.

Plumbers and contractors who need to trace a pipe route before drilling, chasing walls, or breaking ground.

Before your survey, watch for these signs of underground water leak: unexplained water bill increases, damp patches in foundations or floors with no visible source above ground, subsidence or sinkholes appearing in gardens or driveways, unusually lush vegetation growing in specific areas of your property, or a water meter that continues moving when all taps are off.

Ground-penetrating radar is our most powerful tool for mapping what lies below the surface. GPR sends electromagnetic pulses into the ground and reads the reflected signals to build a picture of buried structures.

In Lanzarote specifically, GPR performs well because the island's dry volcanic soil creates good signal reflection conditions, the basalt and pumice layers produce distinctive radar signatures, and the dry climate means ground conditions are consistent and predictable year-round.

GPR can locate both metallic and non-metallic pipes, including HDPE and PVC water supply lines, and can estimate burial depths accurately. A single survey pass can identify multiple buried utilities at different depths simultaneously.

For metallic pipes and electrical cables, electromagnetic locators work by inducing a signal onto the pipe or cable and then tracking it from the surface. This is highly accurate for metal water mains and irrigation pipes, electrical supply cables, telecom and data cables, and earthing conductors.

We trace buried cables and pipes over long distances without disturbing the ground, accurately marking routes and estimating depth at regular intervals. This is particularly valuable before any trenching or drilling work begins on a Lanzarote property or construction site.

Acoustic leak detection works by listening for the specific sound frequency that pressurised water makes as it escapes through a crack or joint in a buried pipe. Our ground microphones and correlators can pinpoint a buried leak to within centimetres, even when it is running at depth below concrete, soil, or paving.

On Lanzarote properties, acoustic detection is particularly effective on main supply pipes entering villas from the road, pipes running beneath pool surrounds and terraces, and underground sections of irrigation systems feeding gardens and landscaping.

Before or after detecting a buried leak, we often recommend a CCTV internal survey of the affected pipe. Learn how to detect underground pipes using specialist equipment. Our drain and pipe cameras can inspect pipes from 25mm upward, giving a clear visual record of the pipe's internal condition.

A CCTV survey confirms exactly where a crack, joint failure, or corrosion is located, whether the pipe can be repaired or needs full replacement, the internal route and condition of the pipework ahead of any excavation, and provides documentary evidence for insurance claims and pre-purchase surveys.

One of the most common requests we receive is from buyers considering a villa or apartment in Lanzarote who want to understand the state of the underground services before completing a purchase.

An underground detection survey as part of a pre-purchase inspection identifies the routes of buried water pipes and any anomalies suggesting leaks, the location of electrical and telecom cables, whether any buried utilities are absent from documentation, and potential issues with irrigation and pool supply pipework.

Knowing what lies below before you buy can save tens of thousands of euros in unexpected repair costs after purchase.

For builders and developers working on Lanzarote construction projects, a utility survey before groundwork is not just good practice. In many cases it is a legal requirement. Breaking through a buried electrical cable or water main is dangerous, expensive, and can halt an entire build.

Canary Detect provides pre-dig utility surveys that map all known and suspected buried utilities across the site, produce marked drawings showing pipe and cable routes and depths, and identify any conflicts between planned excavation and existing buried services.

Many older properties in Lanzarote were built without accurate records of where pipes and cables run. This is especially common in villas and urbanisations built in the 1970s, 1980s, and 1990s.

We carry out full utility mapping surveys of existing properties, producing accurate as-built plans showing the routes and depths of all buried services. This documentation is invaluable for future maintenance, planning extensions or landscaping, community of owners management of shared infrastructure, and property sale documentation.

The cost of an underground survey depends on the size of the area to be covered, the detection methods required, and the complexity of the buried services involved. A straightforward single-pipe trace for a residential property is considerably less than a full utility mapping exercise across a construction site.

We assess the situation before providing a quote, and we work on a transparent, no-surprise basis. All pricing is agreed upfront before any work begins. Our No Find, No Fee policy applies to leak location work - if we are searching for a specific buried leak and cannot locate it, you do not pay for the search.
