Amphibious excavators and marsh plant are the machines that work where conventional plant cannot: sealed pontoon undercarriages and low-ground-pressure equipment for saturated ground, reedbeds, tidal foreshore and shallow water, supported by the barges, pontoons and workboats a wet site depends on. EMIS holds no fleet; the sourcing model specifies the machine to the water, the ground and the duty cycle, then coordinates hire or purchase through trusted hire partners, with the examination and test certification checked before mobilisation, subject to availability and project location.
Between dry land and open water sits the ground most projects dread: saturated margins, tidal foreshore, reedbeds and silt where a conventional excavator sinks and a workboat grounds. Amphibious excavators work exactly there, on sealed pontoon undercarriages that spread the machine's weight until it can float, and around them sits the wider marsh plant family: low-ground-pressure carriers, marsh buggies and tracked machines specified to ground that will not carry a wheel. Beyond them, floating plant, barges, pontoons, crane barges and hopper barges, carries excavation, lifting and material handling over water, with workboats moving crews, plant and materials between shore and works.
Matching machine to environment is the discipline. Water depth, tidal range, bed material, access points and the environmental consent all narrow the choice, and the wrong machine costs throughput every shift, or stands idle waiting for a tide it cannot work. An amphibious plant package also has to fit together: the excavator, the barge it loads, the workboat that tends it and the mooring arrangement that holds it are one system, not four hires.
EMIS sources and coordinates that system from a vetted network of specialist plant partners, plant sourcing for purchase where a scheme justifies it, hire coordination where it does not. We take the method statement, water and ground conditions and programme, specify the spread, and place the order or hire with certification, examination reports, test certificates, insurance, checked before the plant mobilises. Because we keep no yard of our own, the recommendation follows the site and the duty, never a machine that needs work.
The project types and sectors this category most often serves.
River, drain and wetland schemes need amphibious excavators that work saturated ground without destroying it. EMIS specifies the machine to the ground, the reach and the environmental window.
Dredging spreads pair excavators with barges, pipeline and hopper capacity into one compatible system. We coordinate the floating plant so the spread arrives as one programme, not four hires.
Marine structures need floating plant positioned and moored to the works, with workboat support for crews and materials. EMIS coordinates the marine plant package alongside the works programme.
Public-sector flood and coastal works carry demanding compliance and consent obligations. We coordinate certified plant with the documentation trail held ready for the client and regulator.
Vetting, specification and lead-time coordination, handled before the product reaches your site.
EMIS owns no machines, so the specification follows the water depth, ground and duty cycle, never a yard that needs emptying or a hull that needs hours.
Examination reports, test certificates and insurance are verified from trusted hire partners before the machine moves, and held ready for the principal contractor.
Excavator, barge, workboat and moorings are coordinated as one compatible system on one hire programme, timed to the tidal window, not despite it.
