Pipeline structure

Pipelines laid underground need to last at least a couple of generations.

Over a couple of decades, AS Terrat has built hundreds of kilometres of pipelines. Water, sewerage, communications and gas – utilities without which we cannot imagine life in this day and age.

We are used to clean water reaching our homes and wastewater being drained and treated. For decades, we have been helping people to solve problems both in Estonia and abroad.

Once a casing has been laid, any soil and stones in the pipe are purged from the metal pipe, and the necessary water or sewerage pipe is laid. The metal casing will protect the pipeline under the road also against the danger of settlement due to loads aboveground.

Terrat’s Grundoram equipment allows the ramming of a casing up to 700 mm in diameter and up to 60 m long.
