A pergola is a great addition to any yard and a perfect place to host a party. If you are planning on building one, you want to be sure that it is sturdy and stable.
In order to do this, it needs to be anchored well into the ground so that it doesn’t tip over or break when there are people on top of it.
You don’t need special tools or equipment to anchor your pergola well into concrete slab; here are some tips:
| Takeaways |
|---|
| Properly anchoring a pergola to a concrete slab is crucial for stability and longevity. |
| Concrete anchors or anchor bolts are commonly used for securing a pergola to a concrete slab. |
| Preparing the concrete slab by cleaning it thoroughly and ensuring it is level is essential before anchoring the pergola. |
| Using a drill with masonry drill bits is necessary to create holes in the concrete for anchor installation. |
| Once the pergola is anchored to the concrete slab, regular inspection and maintenance are important to ensure continued stability. |
#1. Use A Deadman To Anchor A Pergola To Concrete Slab
The first step to anchoring a pergola to concrete is to install a deadman. A deadman is a large piece of lumber that can be driven into the ground.
The wood should be at least 3 inches thick, at least 8 inches in diameter, and at least 6 feet long.
When it comes to anchoring your pergola to a concrete patio, following the right steps is crucial. Our comprehensive guide on how to anchor a pergola to a concrete patio provides you with the necessary techniques and tips to ensure a secure and stable installation.
#2. Through Bolts Can Secure Your Pergola To Concrete Slab
Through bolts can be installed into your concrete slab. Through bolts are a great option for anchoring a pergola to concrete slab because they go through all the way through your decking and frame, allowing you to secure them with nuts on either side.
To install through bolts:
Make sure that you have access to both sides of the wood frame, so that you can use an impact driver or drill with appropriate bit.
Drill holes through both sides of your frame where it meets up with your decking (if applicable). If there are no spaces between these pieces, then just drill holes through both sides of each piece separately.
| Anchoring Method | Description |
|---|---|
| Through Bolts | Using through bolts to secure the pergola directly to the concrete slab offers a robust and secure anchoring solution. |
| Post Brackets | Post brackets provide a sturdy attachment point for the pergola by mounting the posts onto the concrete slab. |
| Concrete Anchors | Concrete anchors, such as wedge anchors or sleeve anchors, provide a reliable way to secure the pergola to the concrete slab. |
| Anchor Bolts | Anchor bolts are commonly used to anchor pergolas to concrete slabs, providing a strong and durable connection. |
| Expansion Bolts | Expansion bolts, also known as expansion anchors, create a secure connection between the pergola and the concrete slab by expanding within the drilled hole. |
#3. Use A Bolt Down Bracket To Anchor A Pergola To Concrete Slab
In this section, we will talk about the third way to anchor a pergola to concrete slab. This method is called using a bolt down bracket and it is by far one of the easiest ways to install a pergola on your deck or patio.
Bolt down brackets are easy to use, come in many different sizes and shapes, and are usually made of galvanized steel or aluminum.
So what exactly is a bolt down bracket? It’s essentially an L shaped piece of metal that has been drilled through so that you can screw it into your deck or patio while holding up the structure that needs anchoring (like your pergola).
Bolt down brackets should be used when installing structures like lattice panels over doors where you don’t want them leaning against walls for support — because if there were no support underneath these lattice panels would just fall over!

#4. Use Wedge Anchors To Anchor A Pergola To Concrete Slab
You can use wedge anchors to secure a pergola to concrete. If you want to attach your pergola to an existing concrete slab, follow these steps:
Use a hammer drill equipped with a concrete drill bit to drill pilot holes in the slab that are spaced 8″ apart and 5/8″ deep.
Put on safety glasses, protective gloves and earplugs before drilling into the slab so you don’t damage your eyesight or hearing (and so you don’t get hurt).
Drill all of the holes into one side of the concrete at once using firm pressure until they’re all drilled out completely; then flip over your piece of wood so that its top is facing up toward you again and repeat step 2 on this side of it as well so now both sides have been drilled out for wedges!
You’ll need two sets of four wedges total if there’s nothing holding up any walls from falling down onto anyone nearby during construction time one set per wall would suffice though since they’re only being used temporarily anyway until everything else gets put together securely enough not needing them anymore afterwards.”
| Anchoring Method | Description |
|---|---|
| Wedge Anchors | Wedge anchors, such as Red Head Wedge Anchors, provide a secure and reliable method to anchor a pergola directly to a concrete slab. |
| Through Bolts | Using through bolts to secure the pergola directly to the concrete slab offers a robust and secure anchoring solution. |
| Post Brackets | Post brackets, like Simpson Strong-Tie Post Brackets, provide a sturdy attachment point for the pergola by mounting the posts onto the concrete slab. |

| Anchor Bolts | Anchor bolts, like Hilti Anchor Bolts, are commonly used to anchor pergolas to concrete slabs, providing a strong and durable connection. |
#5. Use Sleeve Anchors To Anchor A Pergola To Concrete Slab
You can use Sleeve Anchors to anchor a pergola to a concrete slab without any drilling. They’re easy to install and they are less expensive than other methods, but they may not be as strong as other options.
Sleeve anchors work well in certain situations, but you should consider the pros and cons before deciding if this method is right for your project.

#6. Use Expansion (Masonry) Anchors To Anchor A Pergola To Concrete Slab
Now that you know how to anchor a pergola to concrete, we’ll learn how to do it using expansion anchors.
The expansion anchor is the most popular method of anchoring a pergola. It’s also known as an expansion bolt or masonry anchor.
This type of anchor has been used for over 50 years because it’s fast, strong, and cost-effective. That makes them perfect for attaching heavy objects like pergolas to concrete slabs.
The two main types of expansion anchors are:
- Threaded Expansion Anchors
- Set Screw (Hex Key) Expansion Anchors
#7. Use Hammer-Set Anchors To Anchor A Pergola To Concrete Slab
To install a hammer-set anchor, use a hammer to drive the point of an anchor into the concrete slab. Then use either a chisel or drill to create a hole in which you can insert an expansion bolt.
To do this, make sure you have some anchors and bolts on hand, as well as some tools (such as a drill). You’ll also need:
- Concrete blocks or bricks; these will help hold up your pergola once it’s anchored
- A level
#8. Use Threaded Rods To Anchor A Pergola To Concrete Slab
You can use threaded rods to anchor a pergola to concrete slab. You’ll need a nut and washer on each side of the pergola beam, which will allow you to secure it securely in place with your ratchet wrench or socket set.

#9. Use Hex Head Sleeve Barrels To Anchor A Pergola To Concrete Slab
The ninth step to anchoring your pergola is to use a sleeve barrel anchor. You can use this method if you are attaching the pergola to concrete, masonry or even wood.
A sleeve barrel anchor is a hollow tube that has threads on one end. There are different types of sleeves available and each type will have its own set of instructions for how to install it correctly.
The most common type found at hardware stores is the lag screw version, which requires you to drill two holes in your slab and insert a threaded bolt through those holes using a washer and nut on each side of the bolt head.
This method works well but can be time consuming as you need enough spare screws lying around at home (or know where they’re stored) so that you don’t have issues finding replacement parts when needed down the road!
#10. Use Stud Bolt Rail Clips With Serrated Washers And Hex Nuts To Anchor A Pergola To Concrete Slab
You’ll use a stud bolt rail clip with serrated washers and hex nuts to anchor your pergola to concrete slab. The following are the steps:
Locate a concrete block that is in the same plane as your header beam.
Mark this block with chalk or pencil so that you can drill through it later.
Drill holes into your header beam and into the concrete block using a 1/2-inch drill bit. You should drill two holes on opposite sides of both pieces of wood so that they line up when they’re connected (see image below).
The holes should be centered on each piece of wood, rather than off-center if possible because this will help ensure stability later on once everything is assembled.
| Anchoring Method | Description |
|---|---|
| Stud Bolt Rail Clips | Utilize stud bolt rail clips, such as Simpson Strong-Tie SBRC series, to securely fasten the pergola to the concrete slab. |
| Serrated Washers | Serrated washers, like ITW Buildex Trubolt+ serrated washers, provide enhanced grip and prevent loosening between the stud bolt rail clip and the concrete slab. |
| Hex Nuts | Hex nuts, such as Hilti hex nuts, are used in conjunction with the stud bolt rail clip and serrated washers to ensure a tight and secure connection. |
| Concrete Slab Anchors | Concrete slab anchors, like Red Head Trubolt+ wedge anchors, can be employed in conjunction with the stud bolt rail clips, serrated washers, and hex nuts for a reliable anchoring solution. |
| Post Brackets | Post brackets, such as OZCO post brackets, may be utilized as an alternative anchoring method for attaching the pergola posts to the concrete slab. |
#11. Use Drop-In Anchors To Anchor A Pergola To Concrete Slab
Drop-in anchors are another option for attaching a pergola to a concrete slab. They work best if you’re attaching the beam or post to concrete block, but they can also be used on other materials, such as brick or hollow tile.
Drop-in anchors provide significantly more holding power than expansion bolts because they’re designed to penetrate all the way through the material surface, so they’ll go through both sides of your pergola posts and beams.
This means that they will hold much better than expansion bolts in most situations.
Because they have an internal sleeve bearing surface inside them that creates friction against the inner wall of their hole as well as an outer skin bearing surface on the outside edge of their hole (which makes contact with whatever material is being fastened together)
Drop-in anchors tend to resist movement within their holes without needing external fasteners they have enough self-locking strength built into them from just being installed properly that no additional locking mechanisms are needed!
When it comes to anchoring a pergola in concrete, understanding the right techniques is essential. Our guide on anchoring a pergola in concrete with expert tips covers everything you need to know, ensuring a solid foundation and peace of mind for your pergola installation.
#12. Screws Can Be Used As Concrete Anchors Too!
Screws can be used as concrete anchors too. Screws are better than bolts because they are easier to install and less likely to loosen over time. They’re also more secure, and can be used in situations where the bolt will not fit.
Conclusion
There are many different ways to anchor a pergola to concrete slab. You can use various types of anchors, such as deadmen, threaded rods or bolts and screws.
Each anchor has its own unique advantages and disadvantages so it is important to choose carefully before deciding on which type will work best for your particular situation.
