Renting site fences (Heras fences): when do you need them?
Site fences (often called Heras fences) close off your construction site safely and keep unauthorised people out. You rent them per panel with concrete feet and coupling clamps, and place them on your own land or, with a permit, on the public domain. For shorter or lighter cordons, barriers or crowd control barriers are the better choice.
Almost every construction site of any size needs site fences. They secure the zone, keep materials in and curious passers-by out. Here you can read when you need them and how they differ from lighter cordons.
What are site fences for?
- Closing off the entire site zone against unwanted access.
- Keeping materials, machines and equipment inside a secured perimeter.
- Keeping pedestrians and traffic at a safe distance from the works.
Site fence or barrier?
A site fence is a sturdy, high panel for a long-term, complete enclosure. For a temporary or lighter demarcation (a pedestrian walkway, a short occupancy), a barrier or crowd control barrier is often enough. Which fence suits depends on the duration, the risks and the location of your construction site.
On the public domain: permit required
If the fences stand on the pavement, a parking bay or the carriageway, you need a public domain occupancy permit. If they stand entirely on your own land, you do not. Occupying the public road also often calls for additional signage.
Delivery and installation
We deliver the site fences and accessories to the construction site, with feet and couplers, and install them for you if you wish. Send us the location and the period, and we will align everything with your construction site.

- Who is responsible for putting up the construction site signage?Whoever carries out the works is responsible for ensuring that road signs are correctly installed, even if you put them up yourself. If they are installed incorrectly or do not meet the legal requirements, the police will not tow away illegally parked vehicles and may shut down the construction site.
- Putting up your own parking signs: a summary of the rulesIf you are putting up the parking signs yourself, you must position them exactly as specified in your permit: one set per 25 metres, with the start sign showing the arrow pointing upwards, the end sign showing the arrow pointing downwards, and the dates and times on the lower panels. Take photographs whilst performing the installation and send these, together with the number plates of the cars already parked there, to the police and the municipality.
- Applying for a public domain occupancy permit: how it worksFor works or a container on the pavement, parking strip or roadway you need a public domain occupancy permit. You apply for it per municipality via EagleBE, Spotbooking or the city's occupancy form. Expect a processing time of a few working days to two weeks. We take the entire application off your hands.
