How To Anchor A Pergola In The Ground (Handyman guide)

A pergola is a beautiful addition to your yard. It provides a place to relax, enjoy the shade and spend time with family and friends. 

However, not all pergolas are built to last. If you want your pergola to be sturdy enough to withstand strong winds, heavy snow loads and earthquakes then it needs to be anchored well into the ground. 

This article will highlight several different ways that you can do this yourself or hire someone else to do it for you.

Securing a Backyard Discovery Pergola to Concrete
Anchoring a pergola in the ground is crucial for stability and durability.
Proper tools and materials, such as post anchors and concrete, are essential for a secure installation.
Digging post holes to a sufficient depth and adding gravel or concrete can provide added support.
Attaching the pergola posts to the ground using brackets or post anchors helps prevent shifting or movement.
Regular inspection and maintenance of the anchoring system is necessary to ensure long-term stability.

By using an Anchoring Kit

The first thing you’ll want to do is get some information from the manufacturer of your pergola. Most companies will have a recommended anchoring kit for their products, and if not they can usually tell you what type of anchor should work best with your pergola.

If they don’t have a recommendation, here are some tips on how to choose an anchoring kit:

Make sure it matches the weight limit of your pergola. The average 20x20x7ft garden arbor weighs about 250 pounds; this means that even though it might be possible for you to dig into the ground with just a shovel (and maybe a helping hand from someone else), it’s really not ideal for two reasons: 

First off because digging holes by hand is so much more difficult than using power tools like these; secondly because digging holes this size by hand takes forever! 

So unless there’s no other option available then invest in an electric auger instead it’ll save time and energy while keeping things safe as well.”

When it comes to anchoring a pergola to a concrete patio, proper techniques and materials are crucial. Our detailed guide on anchoring a pergola to a concrete patio provides step-by-step instructions and valuable tips to ensure a sturdy and long-lasting installation.

Using Expansion Bolts

This method is similar to the one you used for anchoring your pergola to the deck. However, instead of using a lag bolt and washers, you will use an expansion bolt. 

These are designed with a tapered head that expands when you tap them into place. 

They don’t require any special tools or equipment; just a few minor adjustments to your tools and techniques from step 2 above.

Drill hole: You will need to drill a hole in the concrete where you want your anchor bolt installed. Use either a hammer drill (which is what most professional contractors use) or hand-held electric drill/driver set at its highest setting the more power behind it, the better! 

Make sure there aren’t any pipes or wires underneath before drilling as they could get damaged by flying debris when drilling through concrete! It’s also best if possible not too close together so no neighboring objects may be affected by vibrations caused during installation process…etc…

Using Garden Spikes

  • Select the location where you want your pergola to be anchored. It should be near a wall or other solid structure that will prevent it from blowing over.
  • Make sure there is enough space in front of the anchor point for your pergola to fit comfortably and not block any walkways or doorways.
  • Dig a hole that is 12 inches deep and wide enough for the spike to fit snugly into place. Remove any rocks or debris from the hole with your hand shovel, then fill it with water until it’s muddy so that when you put down a cement base, it won’t crack as easily during installation.

Looking for an alternative method to anchor your pergola? Consider using pavers for added stability and aesthetic appeal. Our article on anchoring a pergola on pavers explains the process and offers practical advice for a secure and visually pleasing pergola setup.

Using Concrete Fixings

If you’re looking to secure your pergola in the ground, then concrete fixings are a great option. The following steps will take you through installing the fixings and making sure they’re safe:

Dig holes for the anchors using a spade or shovel that’s appropriate to your soil type (e.g., soft clay).

Place the anchor in each hole, ensuring that there is sufficient space between each one so that they don’t come into contact with each other when tightened together later on (around 10cm should be enough). 

If there isn’t enough room between holes, dig out extra dirt from around them until there is sufficient space before re-digging them out again if necessary until you’re happy with their positioning.

Lay down some protective covering over top of where these anchors will be positioned before sinking them into place so as not to damage anything else nearby or cause any unnecessary harm during installation! 

This could mean covering up any grassy areas surrounding where these bolts will go down or even placing cardboard underneath where they’ll be installed if nothing else seems feasible right away 🙂

Using Chemical Anchors

You can also use chemical anchors to attach your posts to concrete. The process for installing these is similar to using lag bolts, except that you’ll be drilling holes into the concrete instead of into wood. 

If you plan on anchoring your pergola in this way, we recommend purchasing galvanised steel chemical anchors since they’re more durable than zinc plated steel ones. 

If you choose galvanised steel anchors, the best type is the JK-XL model which are designed for post diameters ranging from 1/2″ up to 5″.

The installation process:

  • Drill out a hole in your concrete and insert a plug (which comes with each anchor kit) into it
  • Screw on a nut onto the end of each screw until just past where it meets with metal threads (this will ensure that no water gets inside)
  • Insert each screw into its corresponding hole until flush with top surface

By using Post Bases

Post bases are an easy way to anchor a pergola post in the ground. They’re simple and effective, and they can be used with any type of wood post. For smaller posts, they’re a great option.

Post bases are made from concrete or polyethylene plastic, and they fit around the perimeter of your post’s top plate (the part that rests on top of your beam). 

Post bases are generally sold as one piece that both sits inside the hole you dig for your post base, and then screws into place on top of that hole once it’s filled with dirt or gravel.

There are many different kinds of post bases available on Amazon – but here are some tips for making sure you get what you need:

Using Straps and Bolts

Once you’ve determined where to anchor your pergola, it’s time to get started.

Anchoring the pergola with straps and bolts is similar to anchoring it with stakes. The only difference is that instead of using one stake through the middle of each support beam, you’ll use two straps that attach directly to the deck and run through holes in each corner post. 

You’ll also have a long bolt secured into the ground behind each corner post, which will allow you to secure them all together as necessary.

Using this method can be a little more complicated than just driving in some stakes because there are many different layers involved; however, if you follow these steps closely and take your time with everything step by step, then it should go pretty smoothly!

Anchoring a pergola to the ground is a fundamental step in ensuring its stability and durability. Discover the best practices and techniques in our comprehensive guide on anchoring a pergola to the ground, and learn how to secure your pergola firmly into the soil.

By using Stakes

You will need to use a hammer and a stake puller, which is shaped like a pair of pliers.

  • Step 1: pound stakes into the ground with your hammer until they are as deep as possible. (You may have to dig out some dirt first so that you can drive them in.) Then, tighten them with your wrench.
  • Step 2: remove the stakes using your stake puller tool.

For those who prefer a metal pergola, anchoring it to concrete is a key consideration. Learn the proper techniques and necessary tools in our detailed guide on anchoring a metal pergola to concrete, and ensure your metal pergola stands securely and withstands various weather conditions.

Anchor Post to Deck With Bolt Down Brackets

To install the brackets, you will need:

  • Bolt down brackets
  • Drill

Step 1: Place the bracket on top of your deck, and slide it until it reaches the desired height for your pergola post. Make sure that the holes in each bracket line up with one another before drilling them into place. 

If you have a large deck and are installing multiple posts, make sure to leave enough room between each one so that they aren’t touching when installed.

Step 2: Using a drill bit that is slightly smaller than your bolts, drill through each hole in a bracket until they are big enough to fit over your posts’ bolts without being too loose or too tight (you can always add more material if needed).

Anchoring MethodDescription

Concrete FootingInstall a concrete footing beneath the deck to anchor the post securely.
Post Base BracketsUtilize post base brackets to attach the post to the deck, providing stability and support.
Adjustable AnchorsEmploy adjustable anchors to secure the post to the deck, allowing for height adjustment and alignment.
Lag ScrewsUse lag screws to firmly attach the post to the deck surface, ensuring a secure anchoring solution.

By using Screws and Bolts

Use a drill to make holes in the wood. Make sure that you are holding the post level by using a level on top of it, and then make sure that the posts are equal distance from each other by measuring from one post to another with your tape measure.

Now use a screwdriver to tighten up the bolts into place. Be careful not to over tighten them, as this can cause splitting in your wood and make it crack! 

When done properly, this method will give you an anchor that is strong enough for any type of weather conditions (even those hard winter snowstorms) while still being gentle on your budget!

If you’re planning to anchor a pergola to a concrete slab, understanding the correct methods is essential for a successful installation. Our informative article on anchoring a pergola to a concrete slab provides expert tips and step-by-step instructions to help you achieve a solid and reliable anchoring solution.


There are many ways to anchor a pergola in the ground. It all depends on what type of material you have available and how much time you want to spend working on it. 

The most important thing is that whatever method you choose should be reliable enough that it doesn’t come loose over time due to weather conditions or other factors such as vibrations caused by heavy traffic passing through your driveway every day!
