You have a lot to level, a basement to open up, or an area to reshape before pouring the foundations. The jobsite is in the city or in a yard between two walls, access is a gate or a side passage, and the truck can't get in. The question isn't whether to excavate: it's in what order to get the dirt out.
Three machines, three distinct roles
In an excavation job every machine does one specific thing, and mixing them up is the fastest way to lose time.
The excavator breaks ground and loads. It cuts through the soil, lifts it, and moves it within the reach of its arm. It doesn't haul over distance: it works in place and waits for someone to come and collect what it has dug. Where the arm doesn't reach, the material stays put.
The wheel loader — when there's room to maneuver it — pushes and gathers large volumes on flat ground. It's the right tool on open jobsites where there are no walls, fences, or trees acting as barriers. In an urban yard or a garden with tight access it struggles to turn and often can't get in at all.
The dumper hauls. It takes the material the excavator has loaded and carries it out of the jobsite, trip after trip, to the disposal point or the skip. It doesn't dig, it doesn't gather: it does only this, but it's usually what's missing and holds everything else up.
Why on small lots the dumper sets the pace
On an open jobsite with wide access, the dump truck pulls up close to the excavation, gets loaded in a few passes, and drives off. The flow is continuous and the excavator never stops to wait.
On the small lot — the single-family home, the condo yard, the backyard garden — the truck can't get in. The excavator digs and waits, or dumps into a temporary pile that then has to be removed later by hand or with smaller equipment. Every hour lost waiting or moving dirt by hand is an hour paid without making progress.
A compact tracked dumper gets through wherever a worker with a wheelbarrow can, but carries in one trip what the wheelbarrow would take many. The tracks distribute weight across the bottom of the excavation, even when it's wet or freshly loosened, and hold the exit gradient without slipping under load. The bottleneck opens up, and the excavator gets back to work without stopping.
In the Cormidi lineup
The Cormidi dumper lineup covers several sizes, all tracked. For an excavation on a tight lot, the reference machine is the C200: large-capacity skip, cushioned operator platform for long runs or downhill stretches, available with remote control in the RC version for operating it from a distance in less convenient situations. The skip is available in multiple configurations — rear-tip, 180-degree swing, high-dump — so it can be matched to the exact point where the spoil needs to land. For excavations that generate a large volume of material to move, it's the machine that keeps pace with the excavator without needing wide access.
How to organize the flow in practice
The point to settle before starting is where the dirt goes. If there's a skip outside the jobsite, the route from the excavation face to the dump point must be tracked out, leveled just enough, and cleared of obstacles. The dumper makes the same run dozens of times a day: every irregularity slows every single trip.
If the dirt stays on the jobsite for backfill, choose a temporary stockpile area that doesn't block the dumper's path. A pile placed in the wrong spot forces you to move it a second time, and that doubles the work for no reason.
To dig deeper into how different excavation types differ and what impact they have on jobsite organization, it's worth reading Cut excavation: what it's for and how to organize it and Pad excavation and cut excavation: the key differences.
What to check before choosing the machine
Before bringing any dumper to the jobsite, measure the narrowest passage the machine must go through — gate, side opening, fence gap — and compare it with the undercarriage width. Then check the gradient of the route out of the excavation: under load, a steep ramp changes everything. Finally, do a rough calculation of the total volume of dirt to move: if the trips are many, a larger-capacity skip cuts haulage time in half even with the same machine.
To choose the right size and the best attachment setup for your jobsite, contact a local Cormidi dealer: they can assess the access and the type of work before you decide.
