Underground pipelines are affected by their surrounding soils. When providing recommendations for a pipeline, geotechnical engineers consider the potential for settlement, liquefaction, or corrosion by the soil. They provide recommendations for pipeline design based on these and other factors.

Pipelines are supported and covered by earth materials. Proper selection and placement of the materials around the pipe is essential. Geotechnical recommendations are required for the material placed in the pipe bedding, pipe zone, trench backfill and the techniques used to place and compact each material.
