The Underground family is one boring plant sent to two different jobs, and machines that never bore at all: they enter, listen, ride and hold ground already open. Who the family answers, what it will not take, and the way in are all below.
One door serves the whole family, and it opens the same way for every program behind it. The ground settles the architecture down here before a buyer settles anything else.
Every enquiry about the Underground family reaches the same desk every enquiry at Canadian Shield reaches, screened before anything is discussed. There is no second door built for this family alone, and nothing below skips the screen.
The domain decides the architecture. Rock and soil kill a radio signal outright, so guidance down here is a physical optical fibre with a person on the far end of it, carrying the steering, the sensing and the breadcrumb back out. There is no receiver to defeat and no fix to spoof. The Underground family sets out how that works across every program.
They are one machine in two applications rather than two products. What differs is the job the plant is sent to do and the format it is sent in.
One coil reel, one hydraulic straightener, one clamp-and-push stroke drive, one fibre down the tube. The drive clamps the tubing, strokes it forward, releases and resets, and a person steers the head off downhole attitude sensing carried back up the same fibre.
It also stays where you can see it. This is a surface plant: nothing enters the ground but the tubing and the head. The tubing is itself the delivered product where the job calls for conduit left in place, and it retracts back through the drive where it does not. A designation on this family names an application, not a separate machine.
The defence application. CS-410 is the plant pointed at ground that has to be made, not found: a bore driven forward, a conduit laid as it goes, a person holding the loop for the whole run. It is carried to the job on a trailer, on a skid or rigged for an air drop, and the carrier format is part of the specification rather than a separate product.
The civil application. Aquifer CS-411 is the same plant pointed at utility and infrastructure ground: conduit installed along a planned alignment, and the ground logged for conductivity, moisture and strata as the bore advances, a record the utility or civil client uses directly.
Only the plant bores. Everything else enters, listens, rides or holds a passage somebody has already made.
A tracked crawler, carried to a tunnel, culvert or service-passage access point and put in by hand. It maps the passage, sends recon back over the fibre, and carries the sensing a confined space needs before a person enters one.
A passive node, surveyed in, augered or hand-buried, spliced to the fibre, and then the pit closes. It does not move again and it emits nothing over the air. It listens, and it reports over the wire.
What a run of those nodes becomes, strung node to node on a fibre trunk back to one monitored head-end. It detects, localizes and cues a person at the console, and no strike authority exists anywhere in the loop.
A carrier that never touches a bit to soil. It rides pipe, culvert and conduit that already exist, carrying a payload module on the flow of a live line, under its own power where there is none, or on a tether. The line stays in service.
That split is the fastest way to place your own problem inside the family: ground that has to be made is the plant's work, and ground that is already open is everything else.
Read both lists before the enquiry. Between them they settle most of a first conversation.
Nothing here is scoped from a catalogue. The site decides the configuration, and a handful of things answer most of a first conversation.
Everything else is Canadian Shield's to build and to describe. What crosses from your side is short, and it is much the same list whether the job is a utility crossing or a buried perimeter.
Nothing in this family is bought off a page. Screening, counsel and permits are settled before the first exchange, not arranged during it.
A screened enquiry is the one door onto this family, the same door every other program on this site uses. Nothing on this page, or on any page under this family, is an offer or a commitment to any government body. Enquiries sets out the desk in full: one team, one privacy notice, and a person who answers in writing.
Counsel comes first on any international transfer, and a shipment of controlled goods leaves Canada only under a permit issued for that shipment. A civil end use does not move that line: the same architecture and the same export-controlled posture apply either way. Government and ministries carries the tiers a screened enquiry moves through once it opens. Every design in the family is patent pending.
Every page in the family ends at one screened desk, read by the people who run the programs.
Name the ground you cannot put a person into, the line you have to know the inside of, or the passage that has to be entered before anyone walks it. Say which programs you are scoping, or leave that to the desk. The reply comes in writing, from a person.
The family as a whole is on the Underground family page. The plant is on CS-410 and, in its civil application, on Aquifer CS-411. The passage worker is on CS-425, the buried node on CS-430, the chain they become on Trembler Line CS-435, and the carrier that rides an existing line on CS-460. Contact reaches the same team.
All Underground family designs are patent pending; international transfer is export-controlled and subject to Canadian government permits taken per shipment, and nothing on this page is an offer.
