Getting ready mix concrete from the batching plant to your site sounds simple enough, but there is a lot going on behind the scenes. The concrete starts setting the moment water touches the cement, so delivery is a race against the clock. Add in London’s traffic, narrow streets, parking restrictions, and borough rules, and you can see why this process takes real planning and experience.
This guide covers everything you need to know about how ready mix concrete is transported and delivered across London, from the types of trucks used to how quickly you can expect delivery, and how to make sure your site is ready when the truck arrives.
How Ready Mix Concrete Is Made Before Delivery
Ready mixed concrete is produced at a batching plant, where cement, water, aggregates, and any admixtures are combined in exact proportions. According to The Concrete Centre, each batch is tailor-made to the contractor’s requirements, so you get the exact mix you need for your project.
Computer-controlled systems at the plant ensure the proportions are consistent from one load to the next. Once mixed, the concrete is loaded into a transit mixer and the delivery clock begins.
The Trucks Used to Transport Ready Mix Concrete
The most common vehicle for transporting ready mix concrete is the drum mixer truck, sometimes called a transit mixer. The drum rotates continuously during the journey, keeping the concrete in a fluid state and preventing the materials from separating. This rotation means the concrete stays workable and consistent from the moment it leaves the plant to the moment it reaches your site.
Volumetric mixer trucks are another option. Instead of carrying a pre-mixed load, these trucks carry the raw materials separately and mix the concrete on site. This is particularly useful for smaller jobs or awkward locations, as you only pay for the exact volume you use.
For sites with restricted access where full-sized trucks cannot reach, smaller mixer vehicles can be used. These have a tighter turning circle and lower overall height, which helps in areas with low bridges, narrow lanes, or limited manoeuvring room.
| Truck Type | How It Works | Best Suited For |
|---|---|---|
| Drum mixer (transit mixer) | Pre-mixed load, drum rotates during transit | Most standard deliveries |
| Volumetric mixer | Mixes on site from raw materials | Smaller or variable orders |
| Mini mixer | Smaller vehicle for tight access | Residential areas, narrow streets |
How Ready Mix Concrete Is Delivered in London
Delivering concrete in London is not the same as delivering it elsewhere. The capital brings a unique set of challenges that experienced suppliers navigate every single day.
Traffic congestion is one of the biggest factors. Rush hour periods, road closures, and unexpected incidents can all add time to a delivery. This is why proper route planning and GPS tracking are essential. Suppliers monitor traffic in real time and adjust routes where possible to keep deliveries on schedule.
Road restrictions add another layer of complexity. The Ultra Low Emission Zone (ULEZ) and various Low Traffic Neighbourhoods (LTNs) affect which routes are available to concrete trucks. Most modern trucks meet emission standards, but delivery routes still need to be planned carefully around these zones.
Access limitations are a common issue in older parts of London. Narrow streets, resident permit zones, weight limits, and height barriers can prevent larger trucks from reaching a site directly. In these cases, a smaller vehicle or concrete pump may be needed.
Noise restrictions in residential areas can also limit delivery hours. Most standard deliveries take place between 7:00 AM and 5:00 PM, Monday to Saturday, though arrangements for early morning or weekend delivery can sometimes be made with advance notice.
Borough-specific rules mean that large deliveries to major construction sites may require a traffic management plan or special permits. A supplier with strong local knowledge can help you navigate these requirements before your pour day.
How Quickly Can Ready Mix Concrete Be Delivered in London?
Speed of delivery depends on several factors, but in most cases, same-day delivery across Greater London is achievable.
For standard orders placed before 10:00 AM, delivery on the same day is very common. For orders placed later in the day, next-day delivery is almost always available. If you need concrete urgently, some suppliers offer emergency deliveries at short notice, though this may carry an additional charge.
Express Concrete operates four batching plants strategically positioned across London, in Barking, Erith, Wembley, and Chessington. Having plants spread across east, south-east, north-west, and south-west London means most locations across the capital are within a short drive of a facility. Under normal traffic conditions, most London locations are within 30 to 45 minutes of a plant, which helps maintain concrete quality during transit.
Here is a rough guide to what you can expect:
| Scenario | Typical Delivery Time |
|---|---|
| Morning order, standard mix, good access | Same day, 2 to 4 hour window |
| Urgent order, small volume | 1 to 2 hours in some cases |
| Large order needing multiple trucks | 24 to 48 hours notice recommended |
| Late afternoon order | Next morning delivery usual |
These are typical scenarios. Your actual delivery time will depend on your location, the complexity of the mix, and current demand.
Why Timing Matters So Much
Once concrete leaves the batching plant, a chemical process called hydration begins. Water reacts with the cement, and the mix starts to harden. This cannot be stopped once it starts.
Under normal conditions in the UK, concrete has an initial setting time of roughly 30 to 60 minutes. Temperature plays a big role here. In warm weather, this window narrows, meaning you have less time to place and finish the concrete. In cold weather, the setting process slows down, but the concrete still needs careful handling.
This is why timing is so critical when scheduling concrete deliveries. If the concrete arrives before your site is ready, you risk it beginning to stiffen before you can use it. If it arrives late, it may already be too far along in the setting process. Both scenarios can result in wasted material and real cost implications.
The financial knock-on effects of poor timing go beyond the cost of the concrete itself. Labour standing idle waiting for a delivery, equipment hire ticking over, and potential project delays can all add up quickly.
Delivery Scheduling and What to Discuss With Your Supplier
Good communication with your supplier before the delivery day is one of the most important steps you can take. Here is what to think about:
Volume. Make sure your calculations are accurate before you book. Ordering too little can leave you short at a critical point in the pour. Ordering too much wastes money. If you are not sure how much you need, use a concrete volume calculator to check your figures.
Mix specification. Tell your supplier exactly what grade you need and what the concrete is for. Common grades like C20 or C25 are batched regularly and can be dispatched quickly. Special mixes with additives or unusual specifications may need more preparation time.
Delivery window. Rather than specifying an exact time, a 1 to 2 hour window gives your supplier flexibility to work around their schedule while still planning around yours. Morning windows are often preferable as they give you the full day to work with the concrete.
Site access. Be honest about any access challenges. Narrow entrances, low bridges, restricted parking, or ground conditions that might prevent a heavy truck from reaching the pour point all need to be flagged in advance. Your supplier can then arrange the right vehicle or suggest alternatives like a concrete pump.
Permits. If your site requires a traffic management plan or any special permits for the delivery, arrange these ahead of time so they do not hold up the pour on the day.
How to Prepare Your Site Before Delivery
Having your site ready before the concrete truck arrives is essential. Once the truck is there, the working clock is running and every minute counts.
Before your delivery, make sure:
- All formwork is complete and has been checked
- Reinforcement is in place and has been approved if required
- The access route to the pour point is clear and strong enough to take the truck’s weight
- You have enough people on site to handle the pour
- Any required equipment, such as a pump, vibrator, or screed rails, is set up and ready to go
- You have checked the weather forecast and are satisfied conditions are suitable
If unexpected delays occur once the concrete has arrived, the driver can sometimes extend working time by continuing to agitate the drum, but this only buys limited extra time. Clear, honest communication on the day is the best way to avoid unnecessary complications.
What the Delivery Process Looks Like
Once your order is confirmed and your delivery is booked, here is what typically happens:
At the plant: The concrete is batched to your specification and loaded into the drum. This usually takes around 10 to 15 minutes. Quality checks are carried out before dispatch, and a delivery ticket is produced showing the mix details, volume, and dispatch time.
In transit: The driver heads to your site along the pre-planned route. The drum continues to rotate throughout the journey to keep the concrete fresh and uniform.
On arrival: The driver positions the truck at the agreed pour point and begins discharge. Unloading typically takes between 15 and 30 minutes depending on the volume and how the concrete is being placed.
Documentation: Every delivery comes with a ticket showing the mix specification, the volume delivered, and quality information. Keep this for your records, as it may be required for building control or sign-off purposes.
