Construction of the runway base during the development of Sabetta Airport

Drainage installation in the base of a runway embankment with low frost heave. 

«Hydromat 3D» - a drainage mat with geotextile coating on both sides. The material provides drainage at the base of an embankment, separates layers to prevent intermixing, and serves as waterproofing for an airfield pavement. 

The drainage mat consists of a load-bearing component that serves as a framework and retains its water permeability under applied pressure, and nonwoven geotextile that acts as a filter and protects the framework from damage.
