Industry · Mining & Tailings
Reclaim water.
From a deck that doesn't sink.
Tailings ponds are landlocked, toxic, and nowhere near a navigable waterway. Sentinel sections truck in, pin together on the bank, and float a stable platform for reclaim pumps, dredges, and dam-safety crews — anywhere mining happens.
Overview
The barge that arrives by rail.
Tailings management is the part of mining nobody wants to talk about and everybody loses sleep over. The pond sits inland, often hundreds of kilometres from the nearest navigable river, and it has to be actively managed for decades — reclaim water back to the plant, consolidate the solids, monitor the dam, prove regulatory compliance. The equipment that does that work needs a stable, level deck on a body of water no traditional barge can ever reach.
Sentinel sectional barges are built to the same ISO-container envelope as the freight that already moves to your site. Sections arrive by flatbed truck or rail, pin together on the shoreline with our flange-and-pin system, and float a working platform sized to whatever the job needs. Today it's a 30×60 reclaim pump pad. Next year it's a 20×40 dredge tender for tailings consolidation. Same steel, re-pinned in an afternoon.
We supply mining majors, oil sands operators, EPCM consultancies, and tailings-technology vendors working sites in the Alberta Oil Sands, the Pilbara, the Andes, and the Amazon. Every section ships with stamped engineering drawings and Transport Canada approval — the documentation that bonding, regulators, and your dam-safety reviewer all need to sign off.
Applications
What our barges do on a tailings pond
Reclaim water pumping
Stable, vibration-resistant platforms for diesel- or electric-driven slurry pumps that pull supernatant water back to the processing plant.
Tailings consolidation
Pinned decks for centrifuges, mixers, and aeration equipment used to dewater and consolidate fine tailings — reducing pond volume and footprint.
Dam-safety monitoring
Maneuverable inspection floats for hydrographic survey, instrument deployment, and structural assessment of containment dams.
Pipeline routing & support
Floating supports for tailings-line, reclaim-line, and slurry-discharge pipework across active ponds.
Capping & closure
Heavy-deck platforms for placing geotextiles, cover material, and reclamation infrastructure during pond closure and rehabilitation.
Environmental monitoring
GPS sensor arrays, water-quality sampling, and biodiversity monitoring from a stable, low-impact platform that won't disturb pond chemistry.
Why sectional
Why tailings managers specify modular.
You cannot truck a 200-foot ocean barge up a mountain in the Andes or down a forest road in the Athabasca region. You can truck individual ISO-format sections, and that single physical fact is why sectional has displaced custom one-off builds across most of the global tailings sector. The economic case is just as strong: a custom tailings barge designed for one specific pond is a stranded asset the moment that pond closes. A sectional fleet redeploys to the next pond, the next mine, or sells on into another industry entirely.
The chemistry of a tailings pond is also brutal. Caustic and acidic supernatant chew through the wrong steel, the wrong coatings, and the wrong gaskets. We work to your tailings chemistry spec — coating systems, anode placement, gasket compatibility, and inspection intervals are all set up-front, not improvised on-site. Stamped drawings ship with every section so your dam-safety engineer can review the loadout against your regulator's requirements.
For oil sands operators specifically, the precedent is well established — multi-million-dollar reclaim-water programs have used sectional float platforms for over a decade, and the sector is the most demanding regulated tailings environment in the world. If sectional barges meet the bar there, they meet it at almost any mine.
Spec it for your job
Spec a barge fleet for a tailings program.
Send us the pond chemistry, the pump or dredge package you're floating, the access road and rail spec, and your regulator's documentation requirements. We'll engineer a sectional fleet that ships to site by truck, assembles on the bank, and survives the pond chemistry for the design life you specify.

Mining & Tailings FAQ
Direct answers about heavy deck barges, charter terms, and global delivery.
- Yes — with the right coating system and anode design specified up-front. We work to your tailings chemistry data sheet during the quote, select coatings (typically high-build epoxy or specialised polyurethane), and design the anode array for your design life. Inspection and recoating intervals are documented in the deliverables.
- Standard sections carry 36,000 lb per section evenly distributed; Heavy Duty 10×40×7 sections carry up to 58 tons per section. Most reclaim-pump platforms run 4–8 Heavy Duty sections; large dredge tenders run 8–16. We size to your specific pump curve, slurry density, and freeboard requirement.
- That's the whole design. Standard sections ship as oversized flatbed loads; Back Lake 8×20 sections ship as standard freight, two-high on a single trailer with no permits. For overseas mining sites we ship disassembled inside ISO containers — same fleet works in Athabasca or Pará.
- Stamped engineering drawings and Transport Canada approval ship with every section. For specific regulatory frameworks — the Alberta Energy Regulator, Brazil's ANM, Western Australia's DMIRS — we work with your dam-safety engineer to produce any additional documentation needed for sign-off.
- Standard sectional builds run 8–14 weeks; custom builds with specialized coatings, secondary containment, or reinforced loadouts run 12–20 weeks. For multi-pond programs we can sequence shop time to match your construction or shutdown schedule.
