This sour gas line was originally installed in the 1960s on existing farmland. Today, the area is known as the Blackfalds, Alberta Blindman Industrial Park. Since gas lines can, indeed, freeze, they need to safely be buried below the frost line. Recent development had jeopardized the sour gas line, exposing it to the potential frozen fuel line symptoms. For this paving project, our commercial permeable paving partner, along with the Alberta Energy Regulator, chose the Ecoraster permeable paver grid system to protect the surface and the gas line from possible damage.
