The concrete truck discharges on the street, in front of the gate, and the pour is on the other side of the yard — maybe on a slope, maybe past a narrow side passage. Fresh concrete is already moving and setting time doesn't stop while you figure out how to get it where it needs to go. It's that stretch — from the discharge point to the formwork — that determines whether the day runs smoothly or comes apart.
Setting time: the variable that drives everything
Fresh concrete stays workable for a limited time that depends on outdoor temperature, mix type, and humidity. In summer that window shrinks; in winter it stretches, but not by much. Internal transport logistics must treat it as a fixed reference: every wasted trip, every longer route, every extra transfer brings the material closer to setting before it's in place.
This means logistics can't be improvised on pour day. Route, equipment, estimated number of trips: these are decided beforehand, while there's still time to change them.
The wheelbarrow: where it works and where it doesn't
The wheelbarrow is the most common tool for this stretch and makes sense on many jobsites: it's narrow, fits almost anywhere, and doesn't require additional dedicated operators. It works well on short, flat, or gently graded routes, when the volume to be moved is limited and the crew is large enough to run multiple trips in parallel.
The limitation is gradient. On an uphill route with a loaded skip, the wheelbarrow becomes heavy and slow, and whoever is pushing tires quickly. On a downhill route it's worse: controlling the load becomes difficult and the risk of tipping is real. Add an uneven, wet, or dirt surface, and the wheelbarrow stops being the quick solution it appears to be.
The bucket: when a lifting machine is available
If a crane or excavator is already on the jobsite, a concrete bucket is an effective alternative. It's filled at the discharge point, lifted, and emptied directly into the formwork. No horizontal route, no trips on foot.
The constraint is obvious: you need the lifting machine, you need space to maneuver it, and you need a dedicated operator. On a renovation jobsite in a historic district, in a backyard behind an apartment building, or in a tight space between two structures, this approach is often not workable.
The tracked dumper: what changes along the route
Where the wheelbarrow struggles and the bucket can't reach, a tracked dumper covers the stretch on its own. The tracks hold the gradient without the operator having to push against the weight of the load, and they distribute ground pressure in a way that prevents sinking on soft or freshly prepared surfaces.
For transporting fresh concrete, two distinct setups apply, each with a different logic.
The polypropylene skip (POLY) has a smooth interior and empties without material sticking to the walls. After the pour, rinsing is quick. It's the right choice when moving material from the discharge point to the formwork and emptying by gravity with the tip: repeated trips, ready-mixed material, direct pour.
The mixer as an attachment changes the logic of the work: instead of transporting already-mixed concrete, the material is mixed directly on the machine, starting from the aggregates. The drum keeps turning during the trip and the material arrives fresh at the pour point even if the route is long. It's useful when the distance from the discharge point is significant or when work is carried out in multiple stages throughout the day. For more on this solution, read Tracked mixer: how it mounts on a tracked dumper and when it makes sense.
In the Cormidi lineup
Cormidi tracked dumpers are available with a polypropylene skip on the C85, C8X, and C200, and with a mixer attachment on the same models. The C200 has a suspended operator platform, useful on long routes or uneven surfaces. For jobsites where fuel fumes are a concern — enclosed spaces, basements, confined areas — the C85E is the battery-electric version.
What to check before organizing the pour
Before deciding on the equipment, three things need to be measured: the width of the narrowest passage on the route between the discharge point and the formwork, the total gradient to be covered, and the estimated volume of material to be moved. These three answers clarify whether a wheelbarrow is enough, whether a tracked dumper with a POLY skip is needed, or whether it's better to work with an on-board mixer.
