Hoarding Blocks vs Fence Bases: The Right Site Perimeter Base
Hoarding block or fence base in UAE? We compare weight, wind load, panel fixing, and price so you pick the right base for your site perimeter.
The most expensive mistake we see is contractors using light fence bases where a hoarding block is required by DM Order 44 — inspectors catch it, the panel comes down, and the delay costs more than the upgrade ever would. Get the base right first; the rest of the perimeter system follows.
The call we get most often goes like this: “We need bases for site perimeter — what’s the cheapest?” And we ask one question back: is the panel solid or mesh? That answer settles everything else.
Here’s why the distinction matters, and how to pick the right base so your perimeter passes inspection and stays up in a Gulf shamal.
What is the actual difference?
A hoarding block is a heavy precast footing — 600kg or 1000kg — cast at 1000×500×500mm with a vertical hole (48mm or 60mm diameter) through the top for the upright post. Its job is to resist the overturning moment on a solid panel face. When wind pushes on a flat sheet of timber or steel hoarding, the panel tries to rotate at the base. A thousand kilograms of concrete at the foot is what stops it.
A fence base is a compact 25–35kg unit with a round or square post hole. It holds a mesh or chain-link panel upright against its own weight and handles light lateral nudging. Because the mesh lets most wind through, the overturning force never builds the way it does on a solid face.
Different threat, different base. Substituting one for the other is where compliance and safety problems start.
Side-by-side comparison
| Hoarding block | Fence base | |
|---|---|---|
| Weight | 600kg / 1000kg | 25–35kg |
| Dimensions | 1000×500×500mm | Compact footing |
| Post hole | Dia 48mm or 60mm | Round or square |
| Panel type | Solid timber, sheet, plywood hoarding | Welded mesh, chain-link |
| Wind resistance | High — resists full face load | Low — suits permeable panels only |
| UAE compliance | DM Order 44 / Dubai Law No. 7 of 2025 | DM Safety Circular 192 |
| Price (AED) | 165–280 per unit | 32–55 per unit |
| Typical use | Construction site hoarding | Temporary mesh fence, site boundary |
The price gap looks large until you account for what each unit actually does. A fence base under solid hoarding panels isn’t a bargain — it’s a liability.
When does each panel type apply?
Solid hoarding is what Dubai Municipality inspectors look for on active construction sites in built-up areas, roads, and public-facing boundaries. DM Local Order 44/1990 and Dubai Law No. 7 of 2025 both require hoarding that adequately screens the site and withstands normal weather. We’ve supplied hundreds of hoarding packages and the inspector’s first check is whether the base matches the panel. A 1000kg block is the standard we recommend for timber panels — it handles the load, and it’s what the regulation anticipates.
Mesh fencing covers a different set of needs: site internal divisions, storage yard perimeters, compound edges, and project boundaries where screening isn’t required. The panels are light, the fence bases are easy to move, and the whole thing can be reconfigured as the site evolves. It’s not a substitute for hoarding on a public-facing boundary, but it’s the right tool for the job it’s designed to do.
A few situations come up often:
- Temporary road closures: Solid hoarding with 1000kg blocks, because it has to stand up to vehicular proximity and full wind exposure.
- Internal site zones: Mesh panels with fence bases — quick to move, no craneage needed.
- Mixed-use perimeters: We often supply both. The street-facing run gets hoarding blocks, the internal yard gets fence bases.
The wind load question people don’t ask
This is the part that trips up inexperienced site managers. Dubai and Abu Dhabi see wind speeds that can exceed 90km/h in shamal conditions. A solid panel 2.4m tall and 2.4m wide presents about 5.76m² of face area. At 90km/h the wind pressure on that panel is significant — around 1.2 kPa or roughly 700kg of force pushing across the panel face.
A 25kg fence base has no real resistance to that. A 1000kg hoarding block, low to the ground with its mass centred under the post, can. That’s not a sales pitch — it’s the physics the compliance requirement is based on.
Logistics and installation
Fence bases can be hand-lifted and don’t need craneage. One person can carry one. That’s an advantage on constrained sites where you’re setting up mesh perimeters quickly.
Hoarding blocks need a Hiab or crane at 600kg–1000kg each. On most construction sites this isn’t a problem because craneage is already on programme — the blocks go in before the hoarding panels, the crane lifts both. Where it adds complexity is on emergency setups or tight urban sites with limited access. We factor this into the delivery and sequence planning we do with contractors.
The post connection also differs. Fence bases grip the post through the footing geometry. Hoarding blocks are designed to have the post wedged, pinned, or cast into the hole depending on how long the hoarding will stand and whether the site wants the blocks reusable. We can advise on fixing method depending on your programme.
What about refurbished hoarding blocks?
We stock refurbished as well as new. For long-running construction perimeters where the blocks will sit for 12–24 months, refurbished units save real money — the structural capacity is unaffected; they just aren’t fresh from the mould. For high-profile frontages visible to clients or the public, new blocks with a clean finish make more sense.

Frequently asked questions
What is the difference between a hoarding block and a fence base? A hoarding block (600kg or 1000kg) holds solid hoarding panels upright against wind load. A fence base (25–35kg) stabilises mesh panels only. They are not interchangeable — a fence base cannot resist the wind load on a solid panel face.
What weight hoarding block do I need in Dubai? The 1000kg block is the standard for solid timber hoarding panels. The 600kg variant suits lighter applications and mesh hoarding. DM Order 44 and Dubai Law No. 7 of 2025 govern the standard.
How much does a hoarding block cost in the UAE? AED 165 to AED 280 per unit for hoarding blocks; AED 32 to AED 55 for fence bases. Delivery and craneage for the hoarding blocks are priced on top.
Can I use fence bases for site hoarding in Dubai? Not for solid panels. A 25–35kg fence base cannot anchor a solid-face panel against wind load. DM inspection will flag it. Use the 600kg or 1000kg hoarding block for any solid hoarding perimeter.
What diameter post fits a hoarding block? Our blocks are cast with a 48mm or 60mm diameter hole for standard scaffold and hoarding post sizes.
