Engineering-geological, hydrogeological, and engineering-geophysical inspection by superdeep LOZA georadars
About the company
INTERRASCAN – is a part of the INENERGY GROUP, a leading Russian innovative technological company. INENERGY is in the 2019-2020 TechSuccess Ratings: the top 5 most innovative and top 10 fastest growing companies. INTERRASCAN was set up jointly by the authors & developers of the LOZA Series georadars – the Russian innovative technology of superpower radars. The authors of this technology have over 20-year successful experience developing radar and geophysical equipment and creating specialized software.
The patented technologies used in LOZA georadars are a new step in developing geophysical express methods for exploration of subsurface allowing for detailed yet non-destructive inspection of geological space – excluding need for expensive drilling of a range of boreholes on the sites under inspection. The radargrams by LOZA georadars, with their multiple measurement points at each profile meter, ensure drawing up informative and detailed geological sections revealing sink holes (karsts), boulders, landslides, thawing basins, frost heavings, and other geological anomalies.
The LOZA georadars have no analogues in the world in terms of survey depth (down to 300 meters), of inspection scape in water-saturated geological sections and permafrost, exploration of bottom structure inspection of sweet water bodies from their surface in summer and from their frozen surface in winter. The devices work reliably in the temperature range from +50⁰C through -45⁰C. The competitors' attempts to copy LOZA georadars have so far been unsuccessful.
The history of LOZA georadar technologies dates back to the Mars 94 space program which included development of a device for detecting water on the fourth planet of the Solar System. At the beginning of this millennium the first commercial version of this technology adapted to earthly tasks was launched.
Throughout the 20-year history of LOZA georadar operation, over 10,000 geophysical and engineering geological investigations, as well as archaeological searches, have been conducted in more than 20 countries in all the climate zones.
Survey of the construction site of the Snowflake International Arctic Station (IAS) in the Yamalo-Nenets Autonomous District of the Russian Federation. Project operator: Institute of Arctic Technologies of the Moscow Institute of Physics and Technology. The survey task: identification, using non-destructive method, of abnormal structures in the ground of IAS construction site, potentially hazardous to the projected facilities through their service life. The survey result: A fault was detected in the solid rock under the Station's projected facility. The boundaries of the fault were identified. An alternative site for the facility was found – ensuring its basement would rest on a bedrock foundation. The IAS overall construction plan was adjusted accordingly and loss-free at the early design stage.

At suspecting geohazards and/or emergencies Saving up to 50% of costs on detecting emergency causes due to shorter time used for these works and to saving effort and expenses on liquidation of emergency consequences
Draw-up of project design documentation Saving up to 30% of expenses on detailed analysis and verification of original data necessary to design facility foundations
At carrying out time-lapse survey of a facility's current state Allows to save 100% of catastrophic consequences elimination costs due to detection of latent damages in facilities and safeguarding from disastrous accidents
Construction lock-up stage Saving up to 10% of expenses on the constructed facility actual state verification routine
Conditions excluding or limiting alternative investigation methods application Saving 70%+ of costs on alternative investigation methods in complicated conditions (slopes, karsts, landslides, bourocks, remote facilities), excluding as well equipment mobilization costs
Economic efficiency of LOZA Georadar application in engineering geophysics (average values based on results of executed works)
Low cost of investigations High productivity and mobility let set much lower prices for georadar survey works than for geological area investigations by any other alternative methods
Mobility The compact teams operating the LOZA georadars and compact equipment help ensure immediate reaction to customers' requests and promptly send the research teams to any world destination
Shorter work duration Per one work shift a team of four with a LOZA georadar covers up to 10 km of highly detailed profile – which ensures an incomparably higher research productivity against any alternative methods
Reduced drilling and excavation workload The LOZA georadar application dramatically reduces the number of еxploration potholes and wells to be executed for an essentially informative result of geological area research
Economic efficiency of LOZA georadar application in geological investigations Economic efficiency factors of georadar survey application in geological exploration:
Preparation for survey works (5-7 days, depending on timing for approval)
• Work specification • Making contract • Set-off to the site
Field works and survey data interpretation (3-5 days)
• Industrial safety instruction • Survey works • Primary analysis
Drawing up the results (2-3 days)
• Drawing up the report on survey results • Forwarding the report to the customer • Signing the executed work acceptance certificate
