Ditch Witch JT 100
Midi rig, 100k lbs pullbackThe workhorse for utility corridors and mid-range road crossings.
CAPABILITY 01 / 06 · Road & highway crossings
UNDER THE CARRIAGEWAY.
Pipelines, cables and ducts installed beneath live roads and highways with traffic flowing above, to Abu Dhabi Municipality and Department of Transport requirements.
THE SCOPE
Road & highway crossings
Every road crossing starts with the same constraint: the road stays open. Crossroad installs water, sewerage, power, telecom and oil and gas lines beneath carriageways, interchanges, service roads and truck routes across Abu Dhabi, Al Ain and Al Dhafra without a single lane closure for the bore itself. Launch and reception pits sit on the verge or in the median, so the works stay off the carriageway from pilot bore to pullback.
The crossing is designed to the authority's cover and separation rules, not to the convenience of the rig. We survey existing utilities, set the entry and exit angles to suit the available setback, and pick the rig class for the pull load: a JT 60 for service crossings under a two-lane road, a JT 100 for utility corridors and dual carriageways, the HK 250T when the bundle is large or the crossing is long. Every bore is tracked and recorded so the as-built profile is handed over with the NOC close-out.

HOW IT RUNS
SEQUENCE ON SITE
01
Survey and NOC
Utility detection, trial pits where required, and a bore profile designed to authority cover, submitted with the method statement.
02
Pilot bore
A steered pilot hole follows the design curve beneath the road, tracked from the surface at every rod.
03
Ream and pull
Staged reaming to 1.5 times pipe diameter, then the welded string is pulled back in one operation.
04
Handover
Pit reinstatement, pressure or mandrel test, as-built profile and tracking log issued.
See the full four-stage bore animated on the home page, or size your own crossing with the HDD tools.

STRAIGHT ANSWERS
QUESTIONS WE GET ASKED
Engineers answer every enquiry. If your question is not here, send it over.
01Do you need to close any lanes?
Not for the bore. The rig, pits and pipe string sit off the carriageway. Short traffic management is only needed if a pit must be dug in the median or a shoulder, and that is agreed in the traffic plan before we mobilise.
02How deep does the pipe go under the road?
Deep enough to satisfy the authority minimum cover and clear every existing utility with the required separation, typically 3 to 8 m below the pavement. The bore designer on our tools page gives an indicative profile.
03Which approvals do you handle?
We prepare the HDD method statement, bore profile and tracking plan for the NOC package and coordinate with ADM, DoT, ADDC, ADSSC, Etisalat and du as the crossing requires. The main contractor normally remains the NOC applicant.
