Our Technology

Precision Equipment for Non-Invasive Detection

Accurate non-invasive leak detection depends on the right technology and trained technicians. ALD invests in specialist equipment that can listen, see, and sense what is happening beneath your property without excavation. We combine acoustic sensors, thermal imaging, tracer gas, CCTV inspection, ground penetrating radar, and pressure testing to suit the leak, the pipework, and the property. Each method helps confirm the source, reduce guesswork, and locate the problem precisely so repairs can be targeted and your property stays intact.

The Right Technology For Your Situation

Every property is different. Every leak is different. That's exactly why ALD doesn't rely on one single detection technique. We assess your situation, choose the right combination of technologies, and use them systematically to locate your leak with precision. Together, these technologies eliminate guesswork and reveal the truth about what's happening under your property. The result: you know exactly where the problem is, your property stays intact, and your plumber can fix it right the first time.

How We Choose Which Technologies to Deploy

When you call ALD, our technician begins with a detailed assessment of your situation. They ask about wet patches, rising water bills, soft ground, damage patterns, meter locations, property type, building age, and likely construction methods. From there, they create a leak detection strategy suited to the property and symptoms.

A 1960s home with a suspected hot water leak may need thermal imaging followed by acoustic detection while a rural property with a long pipe run may require pipe mapping and tracer gas. ALD uses the right combination of technologies for each inspection under a fixed inspection fee. Your leak is investigated systematically, with the tools and methods needed to produce clear, reliable results.

Why Technology Investment Matters

ALD invests in professional leak detection technology because precision gives customers better outcomes. With acoustic equipment, thermal imaging, tracer gas, CCTV, GPR, and pressure testing, our technicians can pinpoint leaks, document the evidence, and explain what your plumber needs to repair. This turns a frustrating search into a clear, efficient process. Our non-invasive methods also help protect properties and the environment. GPR maps underground utilities before excavation, tracer gas helps locate leaks without multiple test holes, and acoustic or thermal detection can often find leaks without digging at all. With 52 years of experience and a comprehensive equipment suite, ALD can handle complex leaks that basic detection methods may miss.

Not sure what type of leak you have? That's exactly why we exist.

You don't need to know whether it's in the wall, underground, or under your slab. Just tell us what you've noticed, and ALD will take it from there.
