Installing a footer in Post Frame Construction

When building a post frame building it is essential to have a proper footer so the building will not move or shift for many years. In this blog I will briefly detail the process of digging post holes and installing the footers for post frame buildings.

Post Frame buildings get their names from the posts that are essential to the entire structure. They hold up the building while also assuring the building walls will stay straight and square. If these posts are not installed on a proper footer they could sink or shift and then you have all kinds of issues.

After the skilled workers of Wagler Builders LLC have squared up the building (a topic for a later blog) and marked all the footer locations it is time to dig the holes.  Generally our post holes are 8 feet apart. If there are doors or the building length isn’t a multiple of 8 then it is easy to space them at lesser intervals.

The post holes for most pole buildings are 18 inches in diameter. On certain occasions the building is required to have 2o inch, 24 inch, or even 30 inch holes. The depth of the holes is 3 1/2 to 4 feet. The size of the holes depends on the size of the building and where it is located. New Jersey, Maryland, and Pennsylvania all have slightly different codes. The architects and engineers we work with determine what size footer is needed. The footer size is always specified on the building plan that was approved by the local building codes.

We dig all our holes with a Case 1840 skid loader and an auger attachment that works quite well. After the hole is bored we clean all the dirt away from the hole with a shovel. Then we clean the loose dirt out of the hole with a manual digger.

Usually our skid loader digs right down through the dirt. Occasionally we will hit big rocks or shale which is not optimal for nice post holes, but we always manage to get the holes dug. The ground in central Maryland and PA can be quite rocky at times. The soil in New Jersey is often sandy and sometimes if we drill too deep we hit a little water. Here at Wagler Builders LLC we have seen quite a variety of soil over the years and we have dug up a few interesting things. Before digging it is important to check with local utilities about gas, water, or electric lines.

After all loose dirt is cleaned out of holes the first inspection takes place. Most towns and townships these days require a footer inspection. We spend a lot of time waiting on inspectors, but it’s part of the job. Some inspectors measure every hole to make sure it’s deep enough while others glance at one hole and hand us an “Approved” sticker. Almost always the footers are approved on the first try and we are able to continue working.

The next step is to pour concrete into the bottom of the hole. There are several ways to do this. We often use dry sackrete, which will become hard from the moisture in the soil. The second option is to drop a pre-manufactured concrete pole pill into the bottom of the hole. The third option is to pour wet concrete and let it dry before setting the posts.

The advantage of footers used in post frame construction is found in the time and money saved in the installation. While conventional construction will require a footer to be poured around the entire perimeter of the building, a post frame construction footer must only be poured beneath each post. Conventional footers will take days and weeks to install, while a post frame footer can be dug and poured all in several hours. This greatly reduces the cost of the building.

A good strong footer is essential to the post frame building because it is the foundation. While customers save money they are not giving up quality. Here at Wagler Builders LLC we always use footers that are approved by our engineers and meet all state and local building codes.

Welcome to our blog

Hello and welcome to the Wagler Builders Blog. We think a blog will be a good way to update what is going on with our company and also to highlight some of our latest projects. You can also see our latest projects at our Facebook page.

This year has been busy here at Wagler Builders LLC. The cold winter did not help us get off to a good building start. Cold and snow are not optimal building conditions, but we did manage to complete a few jobs in the cold winter months.

In January we completed this 50 x 96 x 14 open front building in Central New Jersey.

The biggest challenge with this building was the 24 foot openings in the front. The three middle posts bear a lot of weight so we actually installed double 6×6 posts there and we cemented them in with wet concrete. Those posts will not move.The headers along the front of the building also bear lots of weight and are quite massive.

By March and April the weather was a lot better for building. In March we put a new metal roof on this 1930s era cow barn.

The old metal had seen its better days and was leaking in some places. We removed the old metal, and replaced the 2x4s as needed. Then we screwed on this galvalume metal. It is unpainted so it is a light silver color. We took down those 4 large cupolas, they were painted, and then put back up.

In April we did a job for a Briarwood Day Camp in Bucks County, PA. The camp is home to hundreds of campers each summer. The owners of the camp were looking to replace some of their cabins. They hadn’t previously heard of post frame construction, but last summer they saw us building a garage near the camp and realized that post frame construction would be a viable option for their new cabins. The price was manageable and they were able to get buildings with wood siding that match the rest of the camp.

As the year has progressed, we have been involved in a number of interesting projects. It is amazing how many different purposes our pole buildings serve. In the future we will detail more of our projects. We will also periodically describe the way a post frame building works. Things like installing footers and posts, setting trusses, installing metal, and putting on wood siding are all topics for later blogs.
