HDD & TRENCHLESS CROSSINGS:

​

• Geotechnical evaluation of proposed directionally drilled pipeline crossings of creeks/rivers/wetlands/steep slopes.

 

• Preliminary crossing profile and drill path development including depth of cover, entry and exit point locations, entry and exit angles, casing recommendations, drilling fluid and equipment considerations.

​

• Access planning, test drilling equipment procurement and implementation of geotechnical investigations for trenchless crossings up to 2,000m in length, including surficial outcrop mapping, test borehole drilling and shallow geophysical surveys.

​

• Test borehole logging, soil sampling and geological interpretation of subsurface conditions.

 

• Geotechnical engineering support in all phases of the crossing construction from route and alignment planning to product pipe installation.
