Road & Highway Crossings
Cross beneath a roadway without cutting it, avoiding lane closures, pavement restoration and the permitting weight that comes with an open cut.
PRIORITY SERVICE 01
Horizontal Directional Drilling
Trenchless installation for crossings beneath roadways, railways, waterways, developed sites and existing structures — with less surface disruption, less restoration and fewer impacts to the work going on above.

OVERVIEW
01 / HDD
Install the pathway without taking the surface apart.
Horizontal directional drilling places conduit and pipe along a designed underground path from a single entry point — no continuous open trench between start and finish.
On a developed site the trench is often the most expensive part of the job. It closes lanes, cuts through finished pavement and creates restoration work that outlasts the installation itself. Directional boring avoids most of that: the rig launches from an entry pit, follows a planned bore path beneath the obstacle, and pulls the product back through on the return.
That makes HDD the right method for crossings under roads, active parking areas, rail, streams and wetlands, and anywhere the surface has to stay in service while the work happens underneath it. It is also the method that keeps a telecom or utility build moving when the alternative would mean permitting and restoring a long open cut.
Mid Atlantic Underground runs directional drilling as a production service for general contractors, national telecom contractors, utilities, municipalities and engineering firms across Pennsylvania and the wider Mid-Atlantic — planned around the site conditions actually in front of the crew, not a generic bore profile.
APPLICATIONS
Where directional drilling
is the right call.
Trenchless is not always the answer — but when access is constrained, the surface matters, or an open cut would stop the project, this is the method that keeps production going.
Telecom & Fiber Conduit
Underground pathways for fiber routes and telecom duct systems, installed to the alignment, depth and separation the design calls for.
Paved & Parking Areas
Get under finished commercial surfaces without taking them out of service or rebuilding them afterward.
Stream & Wetland Crossings
Pass beneath sensitive features where open excavation would create environmental disturbance and a far heavier permitting path.
Utility Crossings
Route new product around and beneath existing underground infrastructure, with the conflicts exposed and verified before the bore starts.
Congested & Tight Access Sites
Work where there is no room for a long trench — active facilities, built-out commercial sites and constrained rights-of-way.
HOW IT WORKS
Three stages,
planned before day one.
A bore is only as good as the information behind it. Most of the risk in directional drilling is resolved before the rig is on site.
Pilot Bore
The drill head follows a designed path from the entry point to the exit, tracked as it goes so alignment and depth stay on profile. Existing utilities along the route are located and exposed beforehand, so the pilot is steered around known conflicts rather than into them.
Reaming
The bore is enlarged to the diameter the product needs, in one or more passes depending on ground conditions and the size being installed. Drilling fluid carries cuttings out and keeps the hole stable while the pathway is opened up.
Pullback
The conduit or pipe is attached at the exit end and drawn back through the reamed path to the entry pit. Once it is through and tied in, the pits are backfilled and the surface restored — a fraction of the restoration an open cut would leave behind.
BIDDING A BORE
What we need
to price it accurately.
The more of this you send with the scope, the tighter and faster the number comes back — and the fewer assumptions end up buried in it. If you do not have all of it, send what you have and we will tell you what actually matters for your site.
Plans, bore profile or a site sketch showing entry and exit
Product size, material and total length to be installed
Known utilities along the route, and any locate or as-built information
Ground and surface conditions — and what sits above the bore path
Traffic control, permitting and right-of-way requirements
Bid date, target start and any schedule constraints
Have a crossing that has to happen without closing the road?
Send the plans and the bid date. We will tell you whether directional drilling is the right method for your site — and price it if it is.
