When it comes to building a pergola, you have a lot of options. You can buy them pre-made and ready to install, or build your own using metal and wood.
When deciding how to anchor your pergola down, you need to make sure that it’s secured properly into concrete or other solid ground, otherwise it could be dangerous for anyone who is walking underneath or even standing on top of the structure.
There are many ways to do this but we’ve put together 17 different methods for how you can successfully secure your pergola in place with minimal effort required from yourself:
|Anchoring a metal pergola to concrete requires proper techniques and materials.
|It is essential to ensure the concrete surface is structurally sound and capable of supporting the weight of the pergola.
|Using anchor brackets and bolts is a common method for securing a metal pergola to concrete.
|Pre-drilling holes in the concrete and using concrete anchors can provide added stability and security.
|Regular maintenance and inspection of the anchor points are necessary to ensure the pergola remains securely attached to the concrete.
|Consulting the manufacturer’s instructions and seeking professional advice can help ensure the proper installation of a metal pergola on concrete.
When building a pergola you need to secure it to the ground using anchors.
When building a pergola you need to secure it to the ground using anchors. Anchors are essentially the same type of anchor that may be used for securing a boat to the shore, but they’re made specifically for use with pergolas and other outdoor structures.
There are several different types of anchors available, each with their own unique features and characteristics:
T-shaped – These are large metal spikes that penetrate into concrete or soil and are usually driven in by hammering them with a sledgehammer or mallet until they’re firmly embedded in place.
These work best when installed on hard surfaces like concrete, but can also be used on softer soils if an additional layer of protection is added underneath them (such as gravel).
Wedge-shaped – Wedge-shaped anchors have tall sides that make them easier to drive into soft soil than conventional T-shaped models because there’s less resistance from their surroundings as they’re being pounded into place.
They also offer greater support than other types because their effective holding power increases dramatically under load conditions meaning they won’t snap off easily like most other options do!
Barbed wire – This type of anchor consists simply of barbed wire attached at both ends so that it forms an X shape when laid flat across any given surface (in this case our pergola).
When installed properly these provide excellent support while remaining flexible enough so not interfere with foot traffic around them too much during normal daily use.”

These anchors need to be fixed into concrete
It’s important to note that these anchors need to be fixed into concrete. You can’t just hammer them into the ground and expect them to hold up under pressure, especially if you’re planning on attaching your pergola outside.
The anchors need to be strong enough to hold the weight of your pergola and withstand weather conditions while they’re holding it up. If you have an outdoor area or balcony with a railing, this will also provide some resistance against wind and other forces that might try to knock over your pergola.
Metal pergolas are strong, secure and last for many years
A metal pergola can provide shelter for your home, whether you’re in a sunny climate or not. Metal pergolas are strong and secure; they’re also much more affordable than other types of pergolas, which makes them a great investment.
If you have an existing structure that needs anchoring to concrete, there are several ways you can attach your new pergola to the ground so that it will last for many years to come.

1. Concrete Screws
Concrete screws are a great choice for anchoring your pergola to concrete. They can be easily installed with a drill and are very strong and durable. Because they’re made out of metal, they can withstand wet conditions without rusting or corroding over time.
2. Hammer-Set Anchors
Hammer-set anchors are used to secure metal pergolas to concrete, and they work best in the following circumstances:
The area in which you want to install your new pergola has been previously worked on or excavated by professionals. This ensures that there is no debris in the ground and that it’s been graded properly for drainage.
You have access to a hammer drill (or impact driver), since hammer-set anchors require driving them into the ground with some force.
A cordless impact driver can make this job easier by eliminating corded power tools from your workspace, but you can use a hammer drill as well you just need an extra set of hands if you plan on using one!
|Hammer-Set Concrete Anchors
|Hammer-set anchors, also known as nail-drive anchors or nail-in anchors, are a type of anchor designed for quick and easy installation in concrete, masonry, or block. They feature a pre-assembled anchor body with a nail or pin inserted through the center. When struck with a hammer, the nail is driven into the anchor, expanding it and creating a secure hold. Hammer-set anchors are ideal for light to medium-duty applications.
|Drive Pin Anchors
|Drive pin anchors, also called drive pins or powder-actuated fasteners, are a type of anchor used for fastening materials to concrete, steel, or masonry. They consist of a metal pin or nail, propelled by a power-actuated tool, which drives the pin into the base material. Drive pin anchors provide a reliable and robust connection for heavy-duty applications.
|Sleeve anchors, such as wedge anchors or sleeve bolt anchors, are versatile anchors designed for use in concrete, brick, or block. They consist of an expansion sleeve, a cone-shaped nut, and a threaded stud. When the nut is tightened, the expansion sleeve expands against the base material, creating a secure and reliable hold. Sleeve anchors are suitable for medium to heavy-duty applications.
|Drop-in anchors, also known as female anchors or drop-in anchors, are internally threaded anchors used in concrete or solid masonry. They are installed by setting them into a pre-drilled hole and then expanding the anchor by driving a setting tool into the anchor, which pushes the internal wedge against the sides of the hole for a secure hold. Drop-in anchors are commonly used in construction and provide excellent load-bearing capabilities.
|Powder-actuated anchors, also called shot-fire anchors or explosive-driven anchors, are fasteners that use gunpowder charges to drive a pin or nail into concrete or steel. They are typically used in construction for attaching fixtures, framing, or other heavy-duty applications. Powder-actuated anchors offer high load capacities and reliable performance.
3. Expansion Anchors
These are metal anchors used to secure fence posts and railings, as well as metal pergolas. They’re also used to secure wood pergolas. They have a hexagonal head, tapered shaft and fluted body.
4. Wedge Anchors
Wedge anchors are a type of anchor that is used to secure metal pergolas to concrete. They are made from a metal wedge and a metal sleeve. The wedge anchor is driven into the concrete, then the metal sleeve is placed over the wedge and secured with a nut and bolt.
The construction process for this kind of anchor can be completed by one person with just some basic tools, but it’s easier if you have someone helping with holding things in place during driving or tightening since wedges tend to move around more than other types of anchors do when inserted into concrete (especially if they’re old/crumbly).

6. Lead Shield Anchors
Lead shield anchors are used in structural concrete. They are also known as expansion anchor bolts and threaded studs.
These anchors are not used in masonry, light-weight concrete or reinforced concrete structures. In addition, lead shield anchors do not have the capacity to support any type of precast structure.
|Lead Sleeve Anchors
|Lead sleeve anchors are versatile anchor types designed for use in solid materials like concrete, brick, or block. They feature a lead sleeve that expands when a screw or bolt is inserted, creating a secure hold. Lead sleeve anchors offer excellent load-bearing capabilities and are commonly used in construction and structural applications.
|Drive anchors, also known as hammer drive anchors or pin drive anchors, are quick and easy-to-install anchors. They are ideal for light to medium-duty applications in concrete, brick, or block. Drive anchors are inserted into pre-drilled holes and secured by hammering the pin into the anchor body, creating a secure connection.
|Lag shields, also called lag screw shields or lipped shells, are anchor types designed for use with lag screws. They are commonly used to secure objects to concrete, masonry, or other solid materials. Lag shields have a flared shape with internal threads that grip the lag screw, providing a strong and stable hold.
|Hollow Wall Anchors
|Hollow wall anchors, also known as wall anchors or Molly bolts, are designed for use in hollow walls, such as drywall or plasterboard. They consist of an anchor body that expands behind the wall surface to provide support. Hollow wall anchors are ideal for mounting lightweight fixtures and objects.
|Plastic anchors, also referred to as wall plugs or expansion anchors, are lightweight anchors commonly used in drywall, plaster, or other soft materials. They are inserted into pre-drilled holes and expand as screws are driven into them, creating a secure attachment point. Plastic anchors are suitable for light-duty applications.
7. Strike Anchors (also called Nail In Anchors)
A strike anchor is a metal fastener used to attach a metal structure to concrete. It is designed to be driven into the concrete with a hammer drill and then bent over at the end of its cycle so it doesn’t pop out again.
They’re typically used for outdoor structures that are exposed to wind, rain, snow, etc., as well as for overhead storage areas like garages or carports. You may also see them referred to as nail-in anchors or cage nuts because they look like cages when installed in your concrete patio surface.
Strike anchors are available in different sizes and finishes (e.g., stainless steel). The size you choose will be based on what size hole you need drilled into your slab before installation begins the smaller the diameter of your anchoring bolt must be so that it doesn’t fall through and which material/finish best suits your needs (e.g., if it’s going directly into grass without any extra sanding needed beforehand).
8. Machine Bolt Screws (T-Bolt Slot Anchor)
The machine bolt screw is a simple and effective way to anchor a pergola to concrete. This type of anchor is installed with a power drill.
The machine bolt screw uses a threaded bolt that is inserted into the anchor, similar to how you would install an anchor in drywall or brick masonry.

9. Lag Shields (Also Called Lag Shields or Lipped Shells)
A lag shield is a piece of metal that is inserted into a hole in the concrete and then secured using a bolt and nut.
The lag shield can then be covered with concrete, which helps to anchor light structures like pergolas.
|Lag shields, also known as lag shields or lipped shells, are anchor types designed for use with lag screws. They provide a secure hold in concrete, masonry, or other solid materials. They feature a flared shape with internal threads to receive the lag screw. Lag shields are commonly used in construction and structural applications.
|Expansion anchors, such as wedge anchors and sleeve anchors, are versatile anchor types that expand when installed to provide a secure grip in concrete, brick, or stone. They are often used in heavy-duty applications and offer high load capacities. Expansion anchors work by wedging or expanding against the base material to create a secure connection.
|Concrete screws, also known as masonry screws or tapcon screws, are anchor types designed specifically for fastening objects to concrete, brick, or block. They feature coarse threads and a sharp, self-tapping tip for easy installation without the need for anchors or pre-drilling. Concrete screws offer a reliable and removable fastening solution.
|Drop-in anchors, also called female anchors or drop-in anchors, are internally threaded anchors used in concrete or solid masonry. They are installed by setting them into a pre-drilled hole and then expanding the anchor by driving a setting tool into the anchor, which pushes the internal wedge against the sides of the hole for a secure hold.
|Screw anchors, also known as lead anchors or lead screw anchors, are anchors that screw into a pre-drilled hole in concrete or masonry. They feature sharp threads and provide a reliable hold when properly installed. Screw anchors are commonly used for light-duty applications and offer ease of installation.
10. Chemical Adhesive Anchoring Systems (Epoxy or Polyurethane)
Chemical adhesives like epoxy and polyurethane are a great choice for attaching metal pergolas, but they do have some disadvantages. Chemical adhesives are incredibly strong and last a long time, but they can be messy to work with, especially if you’re not familiar with them.
Plus, many chemical adhesives will need time to cure before being exposed to UV light or moisture (which means you’ll need to wait at least 24 hours before installing your pergola).
However, chemical adhesive systems are an excellent option if you’re looking for something stronger than traditional anchors without the hassle of using bolts or screws into concrete.
Once applied correctly according to manufacturer instructions and given ample time to cure you’ll be able to enjoy your new garden feature for years without worrying about it coming loose!
