Directional Boring Underground Construction (1)

Underground projects are among the most involved and complicated civil engineering ventures.  There are a number of risks to consider such as economical risk, geotechnical uncertainties and complex technology.

The proper planning, communication and execution of each underground project is crucial to the overall success.

Directional Boring

Boring is commonly referred to as horizontal directional drilling or HDD.  This method is used to install underground pipes and conduits from the surface with minimal impact to the area.

Our teams of San Mateo boring experts have performed these underground projects throughout the Bay area for cities, commercial and residential clients.
