Building a pergola on a concrete patio is a great way to create an affordable outdoor living space. It provides shade and improves the aesthetics of your backyard. While you can always buy a pre-made pergola and install it, DIY pergolas are often cheaper and can be customised to fit your space.
Planning
- Measure and map out the desired size of your pergola.
- Check local building codes and permitting requirements for such a structure.
- Determine the required quantities of material and place an order at your local lumberyard.
Installation
- Prepare the concrete pad by sweeping or brushing away any dirt, dust, or loose particles.
- Mark the anchor points for the pergola posts, ensuring they are evenly distributed for optimal stability.
- Drill holes into the marked anchor points using a hammer drill and masonry drill bits.
- Insert threaded rods and concrete anchors into the concrete anchor brackets.
- Attach the concrete anchor brackets to the pergola posts using screws or bolts.
- Set the pressure-treated posts in the brackets and screw them together, ensuring they are straight.
- Install retrofit post bases for added stability.
- Cut and install the beams, rafters, and purlins as per the pergola design.
- Add optional features such as shade fabric or lighting to enhance the functionality and aesthetics of your pergola.

What You'll Learn
Planning and design
Planning:
Before starting, it is important to check your local building codes and permitting requirements for such a structure. These can vary by jurisdiction, so ensure you are well-informed about the specific regulations in your area. Additionally, assess the suitability of your concrete patio for anchoring. Check for any cracks, ensure the surface is level, and determine the exact anchor points for your fasteners.
Design:
The design of your concrete patio and pergola should not only be aesthetically pleasing but also functional and structurally sound. Here are some key considerations:
- Size and Dimensions: Measure and map out the desired size of your concrete patio and pergola. Consider the available space and any variations in the surface that may require adjustments.
- Materials: Select the appropriate materials for your project, including lumber, concrete, brackets, screws, and other fasteners. Pressure-treated lumber is recommended for outdoor construction, and you may also want to consider using cedar tone lumber for added durability and an attractive appearance.
- Anchor Points: Determine the number and placement of anchor points for your pergola posts. Typically, it is recommended to have at least four anchor points, evenly distributed for optimal stability.
- Concrete Depth: Know the depth of your concrete slab. A typical bolt for concrete surface installation requires a minimum depth of 3 inches, with 2.5 inches embedded into the concrete.
- Attachment Method: Choose the most suitable attachment method for your pergola. Common options include anchoring into a concrete foundation, using concrete footings, or anchoring to a deck with specific brackets.
- Safety: Prioritize safety throughout the design process. Ensure your structure can withstand wind and other environmental conditions. Consider using galvanized bolts and fasteners to prevent rust.
By following these planning and design guidelines, you'll be well on your way to creating a beautiful and sturdy concrete patio with a pergola.

Preparing the concrete pad
Before you start building your pergola, it is important to ensure that your concrete pad is clean and free of debris. Sweep or brush the area to remove any dirt, dust, or loose particles that could disrupt the anchoring process. If you notice any cracks or unevenness in the concrete, address them to ensure a solid and stable structure.
To determine the best anchoring points for your fasteners, check your concrete slab for cracks, levelness, and suitable attachment points. A slight slope on the slab is acceptable as it aids in water dispersal. Additionally, make sure to measure the depth of your concrete; a typical bolt for concrete surface installation requires a minimum depth of 3 inches, with 2.5 inches embedded into the concrete. If possible, perform a concrete strength test using a concrete test hammer or other equipment to ensure the concrete can withstand anchoring.
Once you have assessed and prepared your concrete pad, you can proceed with marking the anchor points and beginning the installation process.
Marking the Anchor Points
Use a measuring tape and chalk line to carefully mark the desired locations for your anchor points. For a stable structure, it is recommended to have at least four anchor points, evenly distributed across the four corners of the base plate on the concrete. This will provide optimal stability for your pergola.
Drilling Holes
After marking the anchor points, use a hammer drill equipped with a masonry drill bit to drill holes into the marked points on the concrete pad. Ensure that the drill bit size matches the diameter of the concrete anchors or threaded rod you will be using. The depth of the holes should be determined by the length of the threaded rod or anchors to ensure a secure fit.
Inserting Threaded Rods and Concrete Anchors
Once the holes are drilled, it's time to insert the threaded rods and concrete anchors. Common types of concrete anchors include expansion anchors and wedge anchors, which provide excellent grip and stability. Use a wrench or socket set to tighten the anchors securely into the drilled holes.
Attaching Concrete Anchor Brackets
Finally, attach the concrete anchor brackets to the pergola posts. Position the brackets at the bottom of each pergola post, ensuring they are aligned precisely. Drill holes if necessary and use a wrench to firmly fasten the bolts until they are snug, being careful not to overtighten. This step ensures that the brackets are securely attached to the pergola posts, preventing any movement or instability.

Marking anchor points
Marking the anchor points for your pergola is a crucial step in ensuring the stability and longevity of your structure. Here are the steps you need to follow:
- Determine the number and placement of anchor points: Depending on the size and design of your pergola, you will need to determine the number of anchor points. Generally, it is recommended to have at least four anchor points, evenly distributed for optimal stability. Mark these points carefully on the concrete using a measuring tape and chalk line.
- Prepare the concrete: Before marking the anchor points, ensure that the concrete surface is clean and free of any debris, dirt, or loose particles. If there are any cracks or unevenness in the concrete, address them beforehand. You may also need to test the concrete strength using a concrete test hammer or other equipment.
- Mark the anchor points: Once you have identified the desired locations for your anchor points, use a hammer drill equipped with a masonry drill bit to carefully drill holes at these marked points. Ensure that the drill bit size matches the diameter of the concrete anchors or threaded rod you will be using. The depth of the holes should be determined by the length of the anchors or threaded rod.
- Install concrete anchors or brackets: After drilling the holes, it's time to insert the concrete anchors or brackets. Common types of concrete anchors include expansion anchors and wedge anchors, which provide excellent grip and stability. Use a wrench or socket set to tighten the anchors or brackets securely into the drilled holes.
- Attach pergola posts: Finally, attach the pergola posts to the concrete anchor brackets. Position the brackets at the bottom of each pergola post, ensuring they are aligned precisely. Drill holes if necessary and use a wrench to firmly fasten the bolts. Ensure that the brackets are tight and secure, providing a strong and durable connection.
