Willowstick applies surface-grid geophysics used on dams to levees, foundations, and other critical civil structures. The interpretation helps owners prioritize groundwater or seepage pathways for direct investigation and intervention without drilling through the asset solely to collect MM-ECD data.

Civil Infrastructure
Protect critical infrastructure from the water working against it.
The Problem
Water undermines infrastructure from below.
Levees, foundations, and embankments fail when water finds a path through or beneath them. The threat develops out of sight, and the cost of a surprise, to public safety and to the asset, is enormous relative to the cost of seeing it coming.

How Willowstick Maps It
The method, applied to civil infrastructure.
01
Establish a controlled circuit: electrodes are positioned so a signature alternating current passes through the area of interest. Its distribution responds to saturation, pore-water chemistry, clay and mineral content, geology, and other controls on bulk conductivity.
02
Measure the response: the Willowstick instrument records the resulting three-axis magnetic field at georeferenced stations on a surface grid. The magnetic survey itself does not require exploratory drilling.
03
Model and interpret: measured data are normalized against a homogeneous-earth reference and processed into 2D and 3D electrical-current models. Site geology and hydrology guide interpretation of preferential conductive connections that may carry groundwater or seepage.
04
Deliver reviewable targets: the report presents mapped anomalies, interpreted pathway targets, model-derived depth ranges where supported, and the assumptions and limits needed to plan direct investigation or remediation.

Field acquisition is often completed in days and interpretation in weeks. Timing, depth of investigation, and deliverables are scoped to the site, method mix, and decision.
