About Our Company

GPR INVESTIGATION

Operating since 2006, GPR INVESTIGATION specializes in Loza-based geophysical investigations for complex subsurface challenges in mineral exploration, hydrogeology, engineering geology, and archaeological research.

Our approach uses Loza-N systems—low-frequency transient electromagnetic instrument designed for analysis of dual-regime (wave-diffusion) responses. This methodology enables investigation of geological structures and conductive bodies to approximately 200 meters depth, depending on site conditions.

Field experience spans 63 countries across 5 continents, from greenstone belts in Zimbabwe, copper belt in Zambia to archaeological sites in Peru, working in diverse geological and climatic environments.

Methodology

Loza Technology Explained

Dual-Regime Physics

Loza operates in the transition zone between wave propagation (GPR) and diffusion (TEM), capturing structural and conductive information simultaneously in a single dataset.

Attribute-Based Analysis

Instead of full 3D inversion, we extract observable attributes (decay slope, late-time curvature, transition time) directly from measured transients for practical drill targeting.

Applications

Mineral exploration (gold, base metals), aquifer mapping, engineering investigations, archaeological prospection, and subsurface profiling beneath freshwater bodies.

Our Approach

Why Work With Us?

Since 2006, we have delivered geophysical investigations in mineral exploration, hydrogeology, geotechnical studies, and archaeology, focusing on projects where conventional methods face limitations.

Our team combines field geophysics expertise with practical deployment experience in Loza systems. We specialize in environments where standard high-frequency GPR lacks penetration and classical TEM lacks structural resolution.

The Loza methodology operates in the transitional frequency range between ground-penetrating radar and time-domain electromagnetics, capturing both structural (early-time) and conductive (late-time) signatures in a single dataset. This dual-regime approach is particularly effective for mineralized systems, aquifer mapping, and subsurface profiling beneath freshwater bodies.

The georadar research of Sacsayhuaman archaeological complex

In recent years the employees of Sacsayhuaman archaeological complex witnessed a number of destructive processes taking place at certain sites of the complex. These consisted of large cracks appearing in the main walls, shifting of stone blocks, and recession of the walls.

Such trends may lead to irreversible and unrecognizable changes to the complex, which remains one of the most significant monuments of Inca heritage. This issue raised a need to conduct a research investigation...
