One-piece, fully welded steel inspection pits for trucks, buses, agricultural machinery and fleet workshops — designed in CAD, fabricated to EN1090 EX2 in our Greenore workshop, and installed complete: excavation, positioning, concrete and finishing, all handled by one Marmion team. Serving Ireland, Northern Ireland and the UK.
■ EN1090 EX2 CERTIFIED ■ FULLY WELDED & WATERTIGHT ■ DESIGN → DIG → DONE ■ MADE IN CO. LOUTH
Our inspection pits are specifically engineered for heavy-duty usage, making them ideal for large vehicles such as trucks, buses, tractors, and cars.
Our team handles the entire process—from designing a pit layout that fits your operational needs to ensuring a seamless, durable installation. With our expertise, you’ll gain a safer and more efficient way to conduct vehicle maintenance and inspections.
We handle everything from initial site assessments and custom design to steel fabrication, excavation, and final finishing. By managing all stages in-house, we maintain strict quality control and keep your project on schedule.
Our EN1090 EX2 certification verifies that each pit we produce meets stringent European standards for structural integrity. This means you can trust our inspection pits to excel under heavy loads and remain compliant with health and safety regulations in Ireland, Northern Ireland, and across the UK.
Every workshop is unique—so are our pits. We work with you to configure pit dimensions, access points, and safety features that perfectly align with your operational needs. If you need specialised compartments or integrated drainage, we’ll design them into the system.
Our inspection and maintenance pits are Constructed using premium-grade steel and reinforced components, our pits are made to withstand daily wear and tear in high-traffic environments. This means lower maintenance costs, minimal downtime, and a long life cycle.
Inspection pits are a must-have for commercial vehicle maintenance—especially for trucks, buses, and agricultural machinery. At Marmion Engineering, we specialise in designing and installing robust steel-fabricated pits that streamline servicing while prioritising safety. Whether you’re maintaining a fleet of HGVs or servicing smaller vehicles in a busy workshop, our pits are built to handle it all.
We address every shortcoming of older pits by employing a fully welded steel frame that’s designed to last:
An inspection pit takes the full weight of your fleet rolling over it, day after day, in ground that’s often wet and always working against it. That’s structural engineering, not groundworks — and it’s why every Marmion pit is a one-piece, fully welded steel structure, fabricated under our EN1090 EX2 certification and delivered to site as a finished unit.
We build pits for HGVs, buses and coaches, agricultural machinery and mixed fleets — each one dimensioned around your longest vehicle, your technicians’ working height, and how your workshop actually operates. One team handles everything: site assessment, CAD design, fabrication, excavation, installation and finishing.
Traditional concrete and blockwork pits share the same life story: hairline cracks, then seepage, then standing water, then patch repairs forever. A welded steel pit breaks that cycle:
Watertight by construction — continuous welds, not joints and mortar, so groundwater stays out even in high water-table sites.
Faster on site — the pit arrives fabricated; excavation and installation are measured in days, not the weeks of shuttering and curing concrete.
Dimensionally exact — CAD-drawn and welded in a workshop, so steps, recesses and services land exactly where designed.
Engineered lifespan — protected steel, built to certified structural standards, made to outlast the building around it.
Walk under, look up, move on — no waiting on a lift cycle. Under-vehicle access in seconds boosts daily throughput.
No hydraulics, no cables, no annual lift certification costs. A pit is a structure — it doesn't wear out or fail with a vehicle up.
A grounded structure with engineered access — no platform sway, no lift-failure risk, with fall-protection options when the pit is idle.
A fully laden artic is no different to a van. No capacity ratings to think about — ever.
Because we fabricate from your CAD drawing, every feature below is welded into the structure — square, level and exactly where the design says.
Stepped or ladder access positioned for your workflow, with handrails where the risk assessment calls for them.
Recessed lighting positions along both walls, so the underside of every vehicle is lit — not shadowed by the technician.
Recessed shelving keeps tools at hand and off the pit floor — nothing to trip on, nothing rolling underfoot.
Ducts and conduits for air lines, power, and lubrication runs, welded in at fabrication — not chased in afterwards.
Falls, drainage channels and sump points designed in, so washdown water and spills go where they should.
Cover and edge-protection options that keep an idle pit from being a hazard — sized to your pit, not an afterthought.
Every pit is fabricated under our EN1090 EX2 certification — the European standard for structural steelwork — so the structure under your fleet is documented, not assumed.
Planning a test lane? We design pits to suit the requirements of CVRT test centres in Ireland and DVSA / ATF lanes in Northern Ireland and the UK — dimensions, access and equipment provisions agreed against the applicable specification before fabrication starts.
Most HGV pits run to a working depth that puts a technician comfortably upright under the chassis — we set yours from your fleet's actual axle heights and your team's working height, not a catalogue default.
From single-vehicle service pits to full test-lane lengths — the structure is welded to your dimensions, not adapted from stock sections.
Ground conditions, water table, slab, services and vehicle flow — surveyed before anything is drawn.
Your pit drawn to your fleet and workflow, with every recess, duct and step agreed on paper first.
Welded as one certified structure in our Greenore workshop while site preparation runs in parallel.
Dig, position, concrete and finish — one team, one accountable handover, workshop back in action fast.
Based at Greenore, Co. Louth — minutes from Dundalk and the border, an hour from Dublin. We install pits nationwide and take on UK projects for fleet and testing clients. Book a free site assessment, or see our other work in fabrication services and gates & entrances.
Deep enough for a technician to work upright under your tallest-axle vehicles — for most HGV fleets that lands around head-height-plus-clearance, but we set the working depth from your actual fleet and your team, then design steps and floor levels around it. It's fixed at the CAD stage, so it's right before a sod is turned.
A welded steel pit is watertight by construction, exact in its dimensions, and installed in a fraction of the time of shuttered concrete or blockwork — which almost inevitably cracks and lets groundwater in over time. Steel costs more per metre than blocks; it's cheaper than a decade of pumping out and patching.
Yes — retrofits are routine. We survey the slab, services and headroom, cut and excavate cleanly, and phase the work to keep as much of your workshop operational as possible.
That's exactly where welded steel wins. The pit is a sealed vessel; combined with proper anchoring and drainage design, groundwater stays outside — no sump pumps running around the clock.
We design to suit the applicable test-lane specification — CVRT in Ireland, DVSA/ATF in Northern Ireland and the UK — agreeing dimensions and equipment provisions against the current requirements before fabrication.
Because the pit arrives as a fabricated unit, on-site time is measured in days rather than the weeks a poured pit needs to shutter and cure. We confirm a programme at the design stage — including phasing for live workshops.
