Pergola Footing Options and the Benefits Provided by Each One

A few different pergola footing options are available out there, but in the end, the primary purpose they serve is to be the support structure’s foundation.

If you are asking does pergola need footings? Then the answer is almost always yes. Less than solid footings will result in unstable frame, which leads to warping and bowing wood that presents harmful risks for anyone using it. It is especially important when reactive soil is involved, where a consultation with local council about the type of suitable footings is required for safety measures.

Here is a list of some recommended pergola footing options to consider:

Concrete-planted posts

This type of post is the most common for structure support due to being relatively simple. It includes a concrete-filled hole built around the post to make it remains steady and straight. It provides solid support for most backyards. Special treatment is needed if the structure is made from wood to prevent damaging pests, along with in-ground rated timber requirement. It’s also important to ensure that the post has proper drainage to let water flow through. Less issues apply for steel posts, which includes moisture leakage but it can be prevented by using hot-dip galvanizing process to hinder corrosion.


Stirrup posts

This type of posts involves covers on the bare open end using a squared stirrup where you can bolt the post. It is a suitable option if you use wooden structure and worry about water seepage, because it makes it easy to detect damage visually on early signs.


High wind post supports

This involves squared and extensive steel loops that have a bracket on either end where you bolt the post. The loop’s primary structure is concreted in. It is a great choice to choose if there’s a potential of water seepage that causes corrosion, because it doesn’t allow any water to run to the center as it doesn’t have hollow space. Support-wise, it also makes a good option for pergolas with taller frames than average.


Brick piers

In general, bricks make a great option as a support structure due to its resistance to rot and pests. It usually stands on footing from concrete material that involves or doesn’t involve a steel rod around for extra support. The piers can be installed directly to the bearers or serves as the foundation to attach steel post. In reactive soils, it also provides good support due to its mass and weight.

Footings are commonly used when one end of pergolas are lifted due to uneven surface or when owners doesn’t want to set a concrete slab. It is best to consult about the best choice from the available pergola footing options with a professional contractor.
