HDD Horizontal Directional Drill

WHAT IS H.D.D ??
It stands for Horizontal Directional Drill. Using the same concept as in DD but with a Horizontal projection.
In other words we have total control on the drilling direction.

ADVANTAGES OF D.D

  • Reduced the number of wells needed to reach these same deposits.
  • Cost efficient.
  • Time saving.
  • Nature preserving. 

as 1St used about twenty years ago.
If the area was not accessible, either due to obstruction by man-made objects or natural obstacles such as mountains , there would be no way to get to the deposits.
D.D. is based on steering of the drill in any direction required.

TELECOMMUNICATION APPLICATIONS:

  • Trench less conduit.
  • Crossings under rivers, lakes, canals and seas.
  • Crossings under highways, parking lots, runways.
  • Crossings under railway tracks.
  • Crossings under of buildings.
