When you are installing a pergola onto a concrete patio, there are several ways to do it. You can use the existing concrete slab as the base for your new structure and anchor it with bolts or screws into the concrete itself.
Or you can install wood plates between the concrete and the wood framing members of your pergola so that they both sit on top of these plates before bolting them together.
However, if you have an old deck or patio that is no longer level or solid enough to support any additional weight, then there may be other options for anchoring that will work better for you.

| Anchoring a pergola to a concrete patio requires proper techniques and materials. |
| Concrete anchors or anchor bolts can be used to secure a pergola to a concrete patio. |
| It is important to ensure that the concrete patio is structurally sound and can support the weight of the pergola. |
| The depth of the anchor bolts should be sufficient to provide stability and strength. |
| Alternative methods, such as post base brackets or surface-mounted post anchors, can be considered for anchoring a pergola to a concrete patio. |
1. Bolting
Whatever you’re anchoring to, you’ll need bolts. Bolts are made of metal and are used with concrete, bricks, posts and fence posts. They’re also a good choice for wood decks and pergolas.
The length depends on what type of material you’re anchoring your pergola to; for instance, if the deck is built on top of concrete blocks then longer bolts will be required because they need more holding power than shorter ones would have
Otherwise given that material alone has little structural integrity when compared against something like bricks or posts which are more rigid materials than concrete blocks typically are.
When it comes to anchoring a pergola to different surfaces, there are various methods you can use. If you’re looking to anchor your pergola to a deck, our comprehensive guide on how to anchor a pergola to a deck provides step-by-step instructions and valuable tips to ensure a sturdy and secure installation.
2. Helical Screws
Helical screws are a handy way to anchor, and they offer many advantages over other options. They’re easy to use, available at hardware stores or online, and can be used with a variety of materials.
Plus, they come in different sizes which allow you to customize the look of your pergola as needed.
For example: if you want to hide the screws inside a lattice top that’s attached by using small-sized helical screws instead of large ones would work well since it won’t make too much noise when people walk underneath it and won’t add any extra weight either!
Most importantly though – how do we install them? The process is simple: drill holes into both sides (top & bottom) where each screw will go into place vertically so that each hole lines up together perfectly straight across from one another (make sure this happens before installing!). Then just tighten down those suckers until their heads are flush against both sides ready for use!”
3. Epoxy
Epoxy is a good choice for concrete. Epoxy can be used in wet or dry conditions, and it’s strong enough to handle the loads of Pergola brackets.
It’s also easy to apply: just mix two parts resin with one part hardener and stir until both become clear. Epoxy needs about 20 minutes of open time before pouring on your surface, so be sure to read instructions carefully.
Epoxies are non-corrosive, so they are ideal for outdoor use and will not rust over time (like screws would).

4. Drilling Anchor Holes and Filling With Concrete
Drill a hole in the concrete pad at least 6 inches deep with a masonry bit or hammer drill.
Pour concrete into each anchor hole until it’s about 1 inch thick, then tamp it down very thoroughly with a tamping tool or flat piece of wood to make sure the anchor is completely covered by the concrete and there are no voids left on top of it.
Repeat this process for each anchor point until you’ve created enough holes for all of your pergola posts to sit comfortably above the patio surface without any gaps between them!
| Step | Description |
|---|---|
| Step 1 | Mark the desired locations for anchor holes. |
| Step 2 | Use a drill to create holes of appropriate size. |
| Step 3 | Clean out the holes to remove debris and dust. |
| Step 4 | Insert anchors into the holes. |
| Step 5 | Prepare concrete mix according to manufacturer’s instructions. |
| Step 6 | Fill the anchor holes with the concrete mixture. |
| Step 7 | Smooth the surface of the concrete for a finished look. |
5. Leverage the Strength of Bricks
Bricks are the strongest material you can use to anchor your pergola. They’re heavy, and they’re also very durable.
If you’re building a brick patio for the first time, then you’ll probably want to hire someone with experience. But if you already have one, then all you should need is some extra mortar and bricks to hold your pergola in place.
There are two ways that this can be done: attaching masonry anchors directly into the concrete or using metal rings around each brick in order to attach them together more securely.
The first method will be much easier since it doesn’t require any special tools or machinery just get yourself some drill bits (the right size will depend entirely on your situation), mix up a batch of quick-set concrete (you’ll only need enough so that it spreads out evenly over each anchor), and start drilling away!
If you have a paver patio and want to anchor your pergola to it, it’s important to use the right techniques for a strong foundation. Our expert advice on how to anchor a pergola to pavers provides detailed instructions and recommendations to ensure a stable and durable installation.
6. Rail Timber Base Plates
The timber base plates are used to support the ends of your pergola. To ensure that they’re strong enough, they should be at least as wide as your pergola’s width and at least as long as your pergola’s length.
7. Deck Foot Anchors
You can also use deck foot anchors to secure your pergola to a concrete patio, but they aren’t as strong as other methods.
They are easy to install and available in various sizes, so you can buy what you need for your project. They’re also available in different styles, such as stainless steel and aluminum.
| Anchor Type | Description |
|---|---|
| Titan Deck Foot Anchor | A heavy-duty, adjustable deck anchor designed for solid support |
| Oz-Deck Post Anchor | A post anchor system for attaching deck posts to the ground |
| Diamond Pier Footings | A precast concrete footing system for supporting deck structures |

| Groundhog Anchor Kit | A kit containing helical ground anchors for deck footings |
8. Fence Post Spike
The fence post spike is a simple and inexpensive way to anchor a pergola or other light structure. It’s also called an “Anchor Bolt,” but you may find people using that term for the concrete anchor as well.
The principle behind this device is very simple: The bolt goes into the ground, where it provides resistance against pushing forces from above.
If you’re on level ground, this prevents your structure from shifting in any direction except up (although there are some circumstances under which installing a fence post spike can cause problems).
These spikes come with large heads that make them easy to drive into the soil with a hammer and long handle driver (we recommend using one at every installation point).
They come in both wood screw-in models and hex head masonry style anchors that require drilling holes in concrete if you’re installing these indoors or on asphalt, we recommend going with the latter option so that they won’t get stuck while trying to install them outdoors
Anchoring a pergola directly to the ground is a popular option that offers flexibility and versatility. Our guide on how to anchor a pergola to the ground walks you through the necessary steps and considerations to securely anchor your pergola for optimal stability.
9. Stake Pocket Anchor

If you’re looking for ways to anchor the posts of your pergola, this is one option you’ll want to consider.
10. Foundation Bracket Anchors
Foundation bracket anchors are another good choice for concrete patios. They are easy to install and can be used with or without concrete anchors.
You can buy the complete system, which includes a foundation bracket anchor and a bolt, or you can buy just the hardware.
If you need help choosing the right size foundation bracket anchor and bolt, we have an article that will walk you through all of your options: Choosing The Right Size Anchor For Your Pergola.
If your pergola isn’t attached to your house, a foundation bracket anchor may be your best bet. It uses two screws (one on each side) instead of one screw like some other types of anchors do. This gives it more bearing strength than other types of concrete anchors available at home centers or hardware stores in many cases.
| Anchor Type | Description |
|---|---|
| Concrete Screw Anchor | A type of anchor that screws directly into concrete surfaces |
| Helical Anchor | A screw-like anchor used for deep foundation stabilization |
