Our technology protects the permafrost; it also reduces the volume of gravel needed for new roads and facility pads resulting in significant cost savings. We use natural materials and the arctic environment to create an insulating layer to maintain the frozen permafrost under new infrastructure.
Permafrost is melting under roads and facility pads in the arctic. Over the past 30 years the ambient temperatures have risen slightly in the arctic. The 24 hour summer sun warms the older roads and pads causing the frozen permafrost to melt leading to subsidence. These older roads and pads were thick enough when placed during the cooler ambient temperatures of the past. Today these roads and pads are sinking into the melting permafrost. Permafrost turns to soft mud when melted.
Arctic engineers call for thicker gravel fills to prevent permafrost melt. The embankments along those thicker fills are subject to accelerated melting of the permafrost. Our technology can help solve the embankment issues.
Ezra Terra has decades of experience in thermal treatment of soils to remove contaminants. This experience led us to develop our new technology to protect the permafrost in the arctic.
