Traffic barriers
The traffic barrier is used to separate a work area or a temporary route from traffic with a visual-physical line. The traffic barrier travels empty and is filled with water or sand on site; its coupling ends join the units into one line. It transports light, sets up fast and redeploys. Its top takes a warning lamp, showing the line at night too. The traffic barrier is used on road works, around site perimeters, at events, and at car park and facility entrances.
- Travels empty, fills on site
- Couples into one line
- No crane — one person sets it out

Technical features
A traffic barrier travels empty and is filled on site. Empty, one person lifts it; filled with water or sand it reaches several hundred kilograms and stays put. Freight cost therefore follows volume, not weight.
The bodies interlock. An interlocked run behaves differently from separate blocks. On light contact the pieces do not scatter and the line flexes as a whole. Ramped end caps or warning panels fit at the ends.
Where freezing is a risk, sand replaces water. Water expands as it freezes and stresses the body. Sand neither freezes nor evaporates, but emptying it is laborious. Water suits layouts that move often, sand suits a layout that stays.
The commonest mistake is leaving the barrier empty. Without ballast it blows over and leaves the road at the first contact. Filling is not the last step of the installation; it is the installation.
The barrier is dried out after emptying. Water left inside grows algae and stains the body by the next season, and emptying before winter prevents both freezing and staining.
Relocation runs in three steps: drain first, then move, then check. A filled barrier is not lifted or dragged — dragging a filled body wears the base and the coupling ends. Before refilling at the new position, the cap, the drain plug and the couplings are checked in order; a missing plug means a leak that goes unnoticed in the first hour of filling.
Technical summary

|---|---|
| Height | 650–1200 mm |
| Base width | 370–800 mm |
| Empty weight | 6–41 kg |
| Water ballast | 60–400 kg |
|---|---|
| Material | UV-stabilised PE / HDPE |
| Fill limit and operating weight | The maximum permitted fill volume and the filled operating weight are stated on the model datasheet; the fill mark on the body is not exceeded. In frost conditions the fill choice follows the datasheet instruction |

Where it is used
- Motorway maintenance. Separates the closed lane and physically divides the work area from traffic.
- Events and crowds. Guides pedestrian flow; carried empty and filled in place, so setup is fast.
- Car park and site entry. Handles temporary closures and diversions without a permanent structure.
- Site perimeter. Encloses excavation and storage areas; takes a warning lamp on top.
- Car park closure. Closes a whole section in one line on an event or maintenance day.
- Temporary footway. Marks out a dedicated temporary walking route when the footway closes; it defines the route, it does not protect against vehicle impact.
Ordering, documents and shipping
Ordering
- Minimum order
- There is no minimum order requirement. Mixed loads are accepted; you are not asked to fill a pallet or a container with a single item.
- Packing
- Export packing: shrink-wrapped pallets or cartons, with pallet size and gross weight stated on the packing list.
- Container
- Shipped empty and filled on site, so the container is limited by volume rather than weight
- Lead time
- Set by the order quantity; the quotation states it in days and the shipment plan is fixed at order confirmation.
- Origin
- Stated in writing per item in the quotation.
- Delivery terms
- FOB · CFR · CIF · DAP
Shipping
- Pallet. Ships empty — the container is limited by volume, not weight · Bodies nest or stack · Connecting pins travel in separate cartons · Freight cost is markedly lower than for concrete

Standard reference
- EN 1317-2
EN 1317-2 defines impact performance, containment classes, working width and impact severity for safety barriers.
Classes T1–T3 are for temporary use only and cannot carry a CE mark; classes N, H and L are for permanent use and are CE-marked.
This is the question to ask when buying a water-filled barrier: which class was it tested to?
Manufactured to the order's specification in the Turkish market. In US language the water-filled traffic barrier is described by the longitudinal channelizing device definition of MUTCD Section 6K.10 (it may be hollow and water-ballasted). These devices are not protection barriers; they are not used to shield obstacles or protect pedestrians or workers. Where impact containment is required, EN 1317-classified systems are a separate conversation. Test results and certificates are shared with the report and the document.
Frequently asked
How much does a water-filled traffic barrier weigh when full?
Empty, one person can carry it. The filled weight varies widely by model; the empty and permitted filled weights are stated on each model datasheet and given in the quotation. That weight is the point: the ballast inside is the only thing keeping it in place against wind and light contact.
Can a traffic barrier be filled with sand instead of water?
Yes, and it is preferred where freezing is a risk. Water expands as it freezes and stresses the body; sand neither freezes nor evaporates. The trade-off is emptying: water suits layouts that move often, sand suits a layout that stays put for a season. A mixed fill is also possible: sand in the lower chamber, water above. That lowers the centre of gravity and the barrier stands more steadily in wind.
How does a traffic barrier load into a container?
Empty — the container is limited by volume, not weight. Because the bodies nest or stack, freight is costed on empty volume rather than filled weight. That is the main reason a water-filled barrier ships so much more cheaply than concrete.
How many years does a traffic barrier last?
Its life is set by sun rather than by impact. Under UV a polyethylene body loses colour and toughness over time. A barrier emptied for winter and stored in shade lasts markedly longer than one left permanently in the open. Once cracks start the body no longer holds water and its ballast function ends, which is the point to replace it.
How are the length and turns of a traffic barrier run planned?
The assembled length is shorter than module length times count: the coupling overlap takes its share at every joint. The turning capacity — the permitted angle between two modules — varies by model and is stated on the datasheet. Couplings of different models or brands may not mate, so a run is built from one model. End caps and warning panels are separate order items. The run plan is drawn from these four facts and issued with the quotation.
