Ist die Installation einer Pergola auf Pflastersteinen sicher? Tipps & Anleitung

Now many people choose to build or install a pergola in their backyard or garden. In this process, they often encounter a problem, and I also encountered this problem when browsing the reddite forum:

Contractor wants to anchor pergola on pavers. Should I veto this?

Actually, it is no problem to fix the pergola on the paving stones, but you need to consider what type of pergola you are fixing (lightweight or pure aluminum), and how to fix it (fix it directly on the paving stones? Or hollow out the paving stones, put the pergola aluminum deep into the ground, and refill the paving to make it a foundation?)

First of all, before answering this question, I will answer another question: why should the pergola be installed on paving stones?

This does not mean that it must be installed on paving stones. It mainly depends on the owner’s preference and the contractor’s advice. For example, a backyard paver patio pergola might be chosen simply because it fits better with the landscape design.

If your family backyard is very large, you can install it anywhere, but if your backyard space is relatively limited, the builder will give you a relatively reasonable installation location based on your yard area and the structural strength of the pergola.

But remember, no matter where it is installed, the most important thing is to secure the pergola

Then, now let’s get back to the topic: is it safe to anchor a pergola on pavers

Whether it is safe depends on how you install the pergola. If you just build the pergola without fixing it, it is very unsafe. Some lightweight pergolas may shift if blown by high-intensity winds, and in severe cases may even hit people.

So what should we do?

First, you need to determine whether the pergola you install is a lightweight pergola or a heavy-duty aluminum pergola. This is the basis for determining the subsequent pergola installation on pavers.

If the thickness of the column structure of your pergola is less than 3 mm, and the roof is a PVC tarpaulin, then your pergola is most likely a lightweight pergola.

Lightweight pergolas are more suitable for installation in areas where there are no strong winds or the wind is relatively mild, such as Western Washington (such as Seattle) and Western Oregon (such as Portland) in the northwest of the United States.

Although these areas often rain, Progolas’s retractable PVC pergola uses high-strength rainproof tarpaulins, which are not afraid of the problem of rain.

The structural strength of this type of pergola is relatively low compared to heavy pergolas, so the installation method of this type of pergola will be a little troublesome. Still, if you’re wondering how to install a pergola on patio pavers, this section is for you

You need to first determine the orientation of the four columns, then hollow out a part of the foundation, bury the columns in the foundation, and then build concrete columns at the anchor bolt positions. Then lay paving bricks on top, drill holes in the columns, and fix the columns there, which will make your pergola indestructible.

Note: Remember to reserve a drainage outlet!

If your pergola is made of aluminum alloy from the columns to the beams to the roof blades, and its thickness reaches more than 2.5mm, then this pergola is a heavy-duty pergola.

For heavy-duty pergolas, there are not so many concerns. It is suitable for any scene and any area. For example, coastal cities in the United States, desert areas in the Middle East, or areas with frequent strong winds. Although these areas have harsh environments, the pergola surface is powder-coated and the pure aluminum alloy structure allows it to be used normally in these environments. Fearless!

There are many options for the installation of this type of pergola. Choosing the best foundation for pergola on pavers depends on your location, wind conditions, and design preference.

If you are more concerned about aesthetics, you can choose to use a metal foundation under the four pillars of the pergola, connect the metal foundation to the ground, and finally tighten the screws to fix the pergola.

If you are looking for something more solid and indestructible, you can choose to use concrete to cast a hollow pyramid frame, bury the metal foundation and the pergola columns in it, and then tighten the screws of the metal foundation. When the concrete solidifies, you will get an indestructible foundation!

Again: remember to reserve a drainage outlet!

The aluminum pergola built in this way not only has a solid foundation, but also has a higher ceiling.
The advantage of this is that it can increase the sense of space, making the room appear more spacious and brighter; creating a visual sense of hierarchy and design to enhance the quality and aesthetics of the living space.

Zusammenfassung:

First of all, it is completely fine to fix the pergola on the paving stones. The key is to ensure that the pergola is firm and avoid safety hazards.​

Then, it is not necessary to install the pergola on paving stones. It mainly depends on the owner’s preference and the contractor’s advice, especially when the backyard space is limited. However, no matter where it is installed, firmness is the first principle. ​

Finally, I hope everyone can use the pergola safely! Blessings!
