We help you optimize your resources and profit

Build a strategic reserve of urea-ammonium nitrate solution (UAN) and fertilizers in the off-season, when the price is usually lower.
Forget about queues when replenishing your stocks of liquid mineral fertilizers. Instead, use your own resources exactly when the field requires it.

Store petroleum products (diesel, gasoline, crude oil) in ultra-strong TPU tanks that withstand temperatures from −60 °C.

A free visit by an engineer and the development of a drawing tailored to the specifics of your site, at the price of a standard solution.

Specialized flexible tanks for a specific type of liquid
Working with GIDROBAK, the manufacturer of the solution, is more advantageous than working with a dealer
We calculate the load individually for you, so that the tank holds its shape and volume as well as possible.
Our patented triple seam means 300% more reliability at critical load points.
We work without intermediaries — payback within 1 season. You get the product directly from the workshop at a fair price.
For over 11 years now we have been using certified raw materials from foreign suppliers and our own patents.
PVC models are always in stock. Custom orders are fulfilled within realistic, fixed deadlines.
We provide post-installation servicing and consultations throughout the entire service life.


Your request – our engineering implementation of UAN storage
Popular volumes of flexible tanks for UAN, liquid complex fertilizers and technical water — 50, 100 and 250 m³ — are in stock. Always ready for shipment for rapid deployment and long-term storage of UAN.
Need a non-standard volume? A GidroBak engineer will come to the site and prepare a drawing. The cost of development is UAH 0 — you pay only for the product.
Only 5 steps
We take measurements, assess the landscape and soil type, and determine the optimal type of material.
We prepare a commercial offer based on our own formula for calculating volumes and loads.
The engineer creates an individual technical solution for your tasks at the price of a standard one.
We manufacture the tank, prepare the site and carry out turnkey installation.
We hand over the documentation, issue the 5-year warranty and, if needed, provide servicing.
