Precast Fence Bases: Sizing Perimeter Footings for UAE Sites
How to size and space a concrete fence base in Dubai: wind load, panel spacing, plastic vs concrete, and when a light footing isn't enough for the shamal.
The call usually comes the morning after a windy night. A site manager walks the perimeter and finds half his mesh fencing flat on the ground, panels tangled, and a gate swinging into the road. The fence didn’t fail. The bases did — or rather, there weren’t enough of them, and the ones there were too light.
Get the footing right and a temporary fence line stays put through a UAE summer. Get it wrong and you’re re-erecting after every shamal. Here’s how we size and space them.
What does a fence base actually do?
A fence base is the deadweight that keeps a free-standing fence upright without digging or bolting into the ground. The panel slots into cast holes; the mass of concrete does the rest.
That’s the whole job — resist the overturning push of the wind on the panel above it. Our reinforced concrete fence footing is cast in C35/45 structural concrete with a steel fibre or 6mm rebar cage, weighs 28 kg to 35 kg, and takes standard Ø40mm frame tubes in two or three apertures. No water, no sand, no filling labour on site. It arrives ready to stand a panel up.
The reason this matters in the UAE specifically: plastic and water-filled feet don’t last here. UV and 50°C surface heat make PVC brittle, the filler leaks, and a half-empty foot is a half-anchored foot. Concrete keeps every kilogram it left the factory with.
How many fence bases do I need?
One base per panel, plus one to close each run, plus an extra at every corner and gate. The base sits under the joint where two panels meet, so along a straight line the count tracks the panel count almost exactly.
A worked example on the common 3.5-metre mesh panel:
| Run length | Panels (3.5m) | Bases (straight run) | Add for corners/gates |
|---|---|---|---|
| 35 m | 10 | 11 | +1 per corner |
| 100 m | ~29 | ~30 | +1 per corner/gate |
| 250 m | ~72 | ~73 | +1 per corner/gate |
| 500 m | ~143 | ~144 | +1 per corner/gate |
The “+1” at the end is the base that carries the last free panel edge. Skip it and the end of the run has nothing holding it down — that’s the panel that goes first in a gust. Corners need their own base because the wind hits a corner panel from two directions.
How do I know the base is heavy enough for the wind?
Match the base weight to the panel area the wind can push on. A standard mesh panel is mostly open, so wind passes through it and the overturning force stays low — a 28-35 kg base holds a bare heras-style panel comfortably through most of the year.
The picture changes the moment you add sheeting. Shade-cloth, banner mesh, or solid hoarding boards turn an open panel into a sail. The same wind now pushes on the full panel face, and the overturning force can climb several times over.
So the rule we give clients: open mesh, light base is fine. Add sheeting, exposed site, or a long unbraced run, and you either step up the ballast, brace the line with returns and corners, or go to a heavier footing. The UAE’s spring and summer shamal can drive sustained wind with gusts well past 50 km/h, and that’s the load the base has to beat — not the calm-day average.
Temporary base or hoarding block?
Pick by how long the perimeter stands and what’s bolted to it. A light fence base is for short-term, open-mesh demarcation. A hoarding block is for the months-long solid hoarding that municipalities require around real construction plots.
| Factor | Concrete fence base | Hoarding footing block |
|---|---|---|
| Weight | 28-35 kg | 600 kg / 1000 kg |
| Panel type | Open mesh / heras | Solid hoarding sheets |
| Tenure | Temporary, weeks | Semi-permanent, months |
| Wind on sheeting | Limited | Designed for full sail load |
| Handling | Two-man lift | Forklift / crane |
| Standard | DM hoarding, BS EN 206 | DM Local Order 44/1990 |
If your project needs continuous solid hoarding — the painted boards around a Dubai plot — the wind load on that sheeting is in a different league, and you want our precast hoarding footing blocks at 600 kg or 1000 kg, cast in 40 MPa concrete with Ø48mm or Ø60mm post holes. Those work to Dubai Municipality’s hoarding regulations, including DM Local Order 44/1990 and the current Dubai hoarding law. Don’t try to hold solid hoarding on light mesh bases. It won’t end well.
How much does a fence base cost in Dubai?
As a per-unit guide, our concrete fence bases run AED 32 to AED 55, with the exact number set by weight, the hole pattern, and how many you order. A 1,000-unit run for a major infrastructure perimeter lands lower per piece than a few dozen for a small plot.
What moves the price:
- Weight and reinforcement — a heavier base with a full rebar cage costs more than a fibre-reinforced standard.
- Hole configuration — two-aperture versus three, round versus square post.
- Quantity — volume amortises the mould and casting setup.
- Delivery emirate and offloading — a palletised drop in Dubai isn’t the same logistics as a sequenced delivery to a remote Abu Dhabi or RAK site.
We cast to dense, void-free concrete under strict vibration protocols and water-cure to ASTM C138 density, because a base that chips on the first handling is a base you’re replacing. The cheapest foot that cracks on delivery costs more than the good one.
Frequently asked questions
How much does a concrete fence base cost in Dubai? Roughly AED 32 to AED 55 per unit, depending on weight, hole pattern, and order quantity. Heavier hoarding blocks for semi-permanent perimeters cost more. Send your panel count and site for a delivered price.
How many fence bases do I need per panel? About one base per panel plus one to close the run. A 100-metre line of 3.5-metre panels takes around 29 to 30 bases, with an extra at each corner and gate.
Are concrete fence bases better than plastic ones? For UAE sites, yes. Plastic and water-filled feet crack, leak, and lose ballast under UV and heat. Reinforced concrete keeps its deadweight indefinitely and is reusable across projects.
Will a temporary fence blow over in UAE wind? It can if the base is too light for the panel area facing the wind. Open mesh on a 28-35 kg base holds most of the year; add sheeting or face an exposed site and you step up the ballast or brace the run.
What is the difference between a fence base and a hoarding block? A fence base is a light 28-35 kg footing for temporary mesh panels. A hoarding block is a heavy 600-1000 kg unit for semi-permanent solid hoarding under Dubai Municipality rules.
A fence line stands or falls on its weakest base, not its average one. We've watched whole runs go down in one shamal gust because someone counted on plastic feet. On a UAE site, concrete deadweight is cheaper than the incident report.
