MALÅ · Ground Penetrating Radar

The Global Standard In Ground Penetrating Radar.

GPR sends radio pulses into the ground and reads the echoes off buried pipes, cables, voids and structures — a complete underground picture with zero excavation. MALÅ sets the global standard: high-tech innovation since the 1930s, the world's first AI-powered GPR, and one range that scales from handheld to 3D array to drone.

Why MALÅ

Capture & Analyse The Subsurface, Effortlessly.

MALÅ, by Guideline Geo, makes ground penetrating radar fast, accurate and accessible — so your team captures and interprets subsurface data effortlessly, for faster, safer and more cost-effective projects.

World's First AI-Powered GPR

MALÅ AI interprets the radar live as you survey — automatically marking buried pipes and cables and converting them to localized utility colour codes. A revolution in the field for new and experienced operators alike.

Patented HDR Technology

MALÅ's High Dynamic Range real-time sampling captures deeper penetration and higher resolution at once, with hyperstacking to strip out noise — razor-sharp data on a single pass.

One Complete Solution

Handheld scanner, modular Ground Explorer, true 3D MIRA array and the GeoDrone airborne radar — all on one MALÅ data workflow, from field acquisition to Vision reporting.

The underground problem

Map The Utilities Others Can't Detect.

Underground corridors are crowded, undocumented and full of non-metallic surprises. MALÅ GPR sees the targets that stop a project — before a strike or a sinkhole does.

Plastic & non-metallic pipes

PVC, HDPE and clay lines carry no signal for EM tools — GPR images them directly by their radar signature.

Voids & sinkholes

Find cavities, washouts and loose ground before they collapse under a road, slab or foundation.

Congested utility corridors

Separate stacked and parallel services in a busy verge, then map each in position and depth.

Rebar, slabs & structures

Locate reinforcement, post-tension cables and buried structures in concrete and ground alike.

Unknown depth & position

HDR returns depth and position for every target — not just a beep, but a map you can act on.

Dig with confidence

Replace guesswork with a verified subsurface picture, cutting strikes, downtime and redesign cost.

The MALÅ HDR advantage

Depth And Detail — Without The Trade-Off.

Conventional GPR forces a choice: penetrate deeper, or resolve finer. MALÅ's patented HDR — High Dynamic Range real-time sampling — delivers both at once. Here's the difference, in one picture.

A lower noise floor means a wider bandwidth.

MALÅ HDR real-time sampling produces data with a significantly lower noise floor than traditional, time-interleaved GPR systems. That lower noise floor opens up a wider usable bandwidth — removing more background interference to give sharper data with higher contrast, and the ability to see deeper than non-HDR systems.

1 Lower noise floor
2 → Wider bandwidth
3 → Sharper, deeper data

↓

Deeper penetration

Reach deeper targets without losing the shallow detail that locates services.

⊹

Higher resolution

Sharper hyperbolas mean more confident interpretation, on every soil type.

≈

Hyperstacking

Random noise stripped out for an unrivalled signal-to-noise ratio.

On the controller

Watch MALÅ AI Read The Hyperbola.

Every buried object shows up in the radar profile as a hyperbola — its signature. In the MALÅ Controller App you view and interpret while data is being collected: MALÅ AI automatically marks each point object live and converts it to a localized utility colour code, right on the tablet.

What The User Sees

MALA Vision Turns GPR Data Into A 3D Mapping Result.

After the field scan, MALÅ data can be reviewed in MALA Vision so buried utilities, voids and anomalies are easier to inspect, explain and report in plan, depth and 3D context.

See targets in relation to the survey path and surrounding subsurface data in clear 3D context.
Move from radar profiles to visual results that are easier for teams and clients to understand.
Support utility mapping, anomaly review and reporting from one connected MALÅ workflow.
