The Best Concrete to Use for Fence Posts

Last updated:

Setting fence posts is not rocket science. You need the right ingredients, the right technique, and a little bit of patience. Any Joe can slap together a fence. But if you want it to stand tall and look smart, you must pick your concrete wisely, not all of them are made equal. 

You could use anything from a premixed bag, home-mixed concrete, or even something from a professional concrete company. It’s all about making savvy choices. 

Should Fence Posts Be Set in Concrete?

Sure, as cows chew cud, fence posts should definitely be set in concrete. This ain’t up for debate. Think about it, the unsung heroes of any fence are the posts. They give you the sturdiness which even the beefiest wood fence posts might fail to contend with.

By the way, when I say concrete, don’t just grab any old stuff. Folks, quality matters. You need high-quality concrete that will lock in your fence posts with a bear hug.

You’ve got to get the right tools such as insulated fence graft, post concrete, fencing tamper, and a level to get it right. Without the right tools, you’re just a sailor without a compass.

Distinct Types of Concrete Suitable for Fence Posts

Concrete for fence posts comes in many flavors. Classic ready-mixed concrete gives you ease, cost-effectiveness and is best for installing a fence without any hiccups. Imagine making your favorite barbeque recipe, only this time the sauce is premixed and ready to cook. 

Goodbye tedious measuring and hello convenience! But there’s always that irresistible urge to test the waters.

The Best Concrete Mix for Fence Posts

Quikrete 50lb Fast Setting Concrete Mix

Setting the stage to the concrete arena, let me introduce you to the heavyweight champion: Quikrete 50lb Fast Setting Concrete Mix. It plays ball as the best concrete mix for fence posts. Picture this as the superhero version of concrete. 

You just pour it in the hole and soak it with water, no need to play chemist and mix this n’ that. For all the fans of instant gratification, Don’t mistake it for flashy; this is top-notch stuf.

Now, there’s an alternative pitching for a place in the market – synthetic foam fence post fillers, or as I like to call them, “the foam posers.” They’re light on weight, rather quick on their feet – setting in 20 to 40 minutes, but they might not strike a ten. Concrete will harden substantially more in terms of compressive strength. 

Assessing How Many Bags of Quikrete You Need

Now boys and girls, here’s the important piece of this jigsaw puzzle – how many bags of Quikrete you’d need. Now you don’t need a PhD to figure this out. 

But like measuring sugar for your apple pie, you gotta get this right. Too little and your posts might lean like that famous tower in Italy. Too much and, well, you’d be spending more dollar bills than you’d prefer.

So, how to hit that sweet spot? Don’t you worry, there are concrete calculators around to lend a helping hand. Just pull out one from your handy internet machine, plug in the required measurements, and voila! You’d get a ballpark figure. Oh, and don’t forget to cross-check using calculators from different websites, you know, just to be sure. 

An Insight Into Sika Fence Post Mix

Ever wondered why folks rave about Sika Fence Post Mix, rightly classifying it as a game-changer? Well, this stuff ain’t concrete, bub. Completely separate league. This genius little invention is especially whipped up to set a fence post, like making the perfect pie crust – just right for the job.

So, this is the techy bit. We’re talking about a 2-part, pre-measured polyurethane resin. Picture it – poured into the hole and metamorphosizing into an expanding foam. Nifty, huh? 

This foam’s got the secret strength of those burly strongmen at the county fair, no kidding. It can bear the load for just about any size fence post and shows no favoritism to different post makeups – wood, steel, or PVC, it’s all the same to Sika. Not only that, but the mix can set in as quickly as 3 minutes. 

This stallion doesn’t need water to whip it up into shape – a cheery thought for when you’re setting fence posts in those parched landscapes where water takes a raincheck.

How to Ensure a Strong Post Base

No matter how you mix concrete or what type you use, you must ensure the base can withstand a hurricane – figuratively speaking.

It’s a simple recipe – dig that hole deep and wide enough, according to the kind and size of your fence post. Remember, your fence ain’t stronger than the soldiers it sends to the battlefront, the posts! It’s like having nachos without salsa – looks good, but can’t stand on its own. 

The weightier the concrete footing, the better off you are. Even average Joe concrete can withstand a few jostles because it’s pretty hefty. Think of it this way – if numerous bags of heavy concrete are all bunkered down, the base starts looking more like the superman of fence foundations!

Noteworthy Tips on How Concrete Can Be Formed

Okay, there’s another thing to remember. You know how fine wines are distinguished by appearance, scent, and taste? Well, it’s the same with concrete. The way that stuff is formed makes a load of difference. 

Case in point – fence post concrete can actually be shaped and moulded to suit your requirements, just like a clay artist. Concrete can be poured into a tube and shaped smooth. It’s like making a perfect marble statue out of a hunk of rock. 

And the best part? This gives your fence post foundation an appearance as impressive as the crown jewels! If part of your fence post foundation is above ground, this molded concrete works wonders.

Crucial Factors to Consider when Selecting Concrete Mix for Fence Posts

State of the Bag

The bag is what holds your knight in shining armor, your 50lb bag of concrete. Now, don’t be fooled by its lightweight look. Yes, it’s lighter than your standard concrete bags weight category but don’t underestimate it. 

You’ll need multiples of these bags per hole to do the job, like a team of ants carrying a sugar cube. Each bag of Sika is only about 2lbs, less daunting but just as strong. It’s like carrying a chicken instead of the whole barn, still serves the purpose and easier on the back.

Brand of the Concrete Mix

Cross my heart, not all concrete mixes are created equal. Some make the cut while others, well, let’s just say they’re riding on the coattails of the real deal. Quikrete Fast Setting Concrete Mix, ain’t just a mouthful, it’s as good as any other out there. 

If it was a cowboy, it’d be the fastest gun in the west. It’s an easygoing bloke who sets up fast, doesn’t require extra care and won’t keep you standing at the mixing bowl. It’s like the express checkout line you wish your grocery store had.

Water Ratio

Here’s a trade secret if you’re making a concreting fence post. Take one part cement, two parts sand and four parts aggregate. It’s your magic potion for the perfect mix. Don’t have a cement mixer? No fret, hand mixing can do the job. Though, it’s kind of like making scrambled eggs with a toothpick when you could be using a whisk.


For any good DIY job, believe me, instructions are your crystal ball. It’s your cheat sheet or your glimpse into the future. Like maps at amusement parks, they show you where to go and how to get there. Don’t dust it off like the terms and conditions of an app update. It could be the difference between your fence standing tall or tumbling over like a tired sumo wrestler.

Choosing Your Best Concrete for Fence Posts

Alright, folks, time to wrap it up. Remember, setting up fence posts is like carving an ice sculpture – mess it up and you’re left with a messy puddle. So, don’t be too hard on yourself when choosing the perfect concrete for the job. 

Keep a keen eye on the way the concrete sets in the center of the hole, whether it gets along with the surrounding soil, and how it behaves in cold weather. Practice makes perfect so hang in there; you’re only a couple of 50 lb bags away from becoming the local fence post connoisseur!
