We are a family-owned Czech company with its own technological background for the development and production of equipment for geophysical exploration. We have been working on georadar development since 2012 and during that time we have managed to develop one of the most powerful georadar in the world.
We strive to provide comprehensive services for geophysical exploration. We are constantly working to improve our Roteg georadar, which, thanks to its parameters, ranks among the world leaders. We actively participate in conferences and constantly educate ourselves in the field.
What we can find
Georadar measures the reflection time of electromagnetic pulses. This allows us to locate all kinds of anomalies below the surface. Thus, we find wells, caverns, pipes, cables and all kinds of other anomalies that have different conductivity or permittivity from their surroundings.
What equipment do we have
Georadar ROTEG is suitable for both archaeology up to a few meters and geology up to hundreds of meters. We use it for most surveys. Its geographic range does not match any georadar in the world.
EASY LOCATOR is mainly used for interior surveys (thanks to its shielded antenna), and for searching smaller utility networks. With a 500 MHz antenna, its range is up to approx. 4 m.
DEEPMAX Z1 is a super powerful pulse metal detector. With a large spool of 3x3 m it is possible to find, for example, a cannon ball up to a depth of 5 m.

This makes our georadar ROTEG really unique!

What kind of services do we provide
Georadar surveyUsing georadar we are able to track anomalies under the surface - places with different conductivity or permittivity to their surroundings. This way we can find underground corridors, caves, utilities, graves, wells, etc. More info
Radargram evaluationDo you own a new georadar and do not know how to measure the data? We’re more than happy to evaluate the data from the georadar for you.
Drilling the anomaliesFor drilling of found anomalies we use various means depending on the depth and composition of the subsoil. From hand drills up to several meters to the EMCI drilling rig to greater depths.
GPS trackingGeoradar ROTEG records the GPS position with an accuracy of 1 meter. In a relatively short time, we can measure a larger area without having to accurately track each profile, and then locate the anomalies found, for example, in Google Earth, where you can assign a radargram with an anomaly to each GPS point. See below for a demonstration of a field survey in Vysočina.
Old wells and cellars"I need to find an old well / cellar on the property." This is the kind of sentence we hear very often, as those are the most common surveys for individuals.

Utility network tracingWhen project plans do not match reality and the pipes / cables run elsewhere than expected. Do you want to make sure that you will not interrupt the utility lines during excavation?

Underground tunnelsDoes the castle lead to an underground passage? Do I have an underground passage on the property? We can answer these kinds of questions quickly. We are able to locate underground corridors to a depth of several tens of meters.

CavesWhen searching for caves we cooperate with speleologists who have an overview of the situation in the karst areas and already know the famous caves very well. As we know the location of the already known caves, it makes it possible to compare and verify them with our measured data. Often in their surroundings, we can also find caves that have not been discovered - till now :)
