A unique year-long experiment that could significantly change the approach to construction on permafrost has recently begun in the Arctic, at the "Obdorsky" scientific and technological test site in the Yamalo-Nenets Autonomous Okrug.
The experiment involves testing a "flexible slab" — a new type of building foundation.
Instead of a traditional concrete screed, which rarely lasts long in the harsh conditions of the Far North, a profiled PLANTER Standard membrane with a crushed-stone protective layer will be tested.
Its key advantage is the ability to adapt to seasonal ground movement without damage.
This project is being carried out jointly by the Scientific Center for Arctic Studies and the company TECHNONICOL.
The project's goal is to find a durable, high-quality alternative to concrete.
The membrane has frost resistance down to -45 °C, complete water resistance, a design service life of at least 60 years, and — importantly for the North — ease of installation, allowing the work to be completed within the short construction season.
The structure with a ventilated underfloor space and flexible slab effectively drains water and prevents permafrost thawing beneath the building, reducing the risk of foundation subsidence. This is important amid climate change and increasing ground instability.
The main challenge for the project is global warming and permafrost degradation.
The experiment is designed to test how effectively the new technology can withstand these risks over a full Arctic cycle.
The projected economic benefits look convincing:
✅ extending the foundation's service life to 60 years;
✅ significantly reducing the costs of repairing and restoring facilities;
✅ fast installation.
Improved foundation stability will make Arctic infrastructure safer and more reliable.
The technology already has a successful precedent — its use in the construction of the airport terminal in Magadan.
If the year-long experiment in Yamal confirms its effectiveness, it will pave the way for widespread adoption of the innovation across the Arctic.
We are following the project's development with great interest!
