How deep should fence posts be pa?

For regular privacy fences, holes should be placed at least 36 inches deep, or half the fence height if taller, plus 6 inches for base gravel. Larger fences will require deeper holes. If you plan to install a post every two feet, dig holes twice as deep as the posts. You’ll also need to consider your soil type. Sandy soils tend to compact easily, so you’ll need to add extra weight to keep the hole stable. Clay soils won’t compact as well, so you might need to add less weight. Digging a hole for a fence requires a lot of effort, so you’ll probably want to hire someone else to do it.

How deep do I need to dig my footings?

Footings should extend to a depth of 12 inches below the surface of the earth. Footings also need to extend at least 12 inches beneath the frost line. If you live in an area where there is snow cover during the winter months, footings may need to be protected against freezing.

What is the Frost Line?

The frost level is the lowest point at which the water in the ground freezes. If you dig down deep enough, you should see the frost line. Digging down until you hit the frost line ensures that the soil beneath your foundation won’t freeze during the winter.

In warmer climates, like Florida, you may be allowed by your local building inspector to place your footings directly on grade. However, in colder climates, like Minnesota and Canada you will need to dig your footings down 96 inches or more before placing them on grade. You should always check with your local building inspectors to see what is required for your area. Also, you must install footers at least 12″ below settled soil. If you are digging into a steep slope or beside a retaining wall, you will need to maintain the minimum distance both vertically and horizontally. To create a suitable lateral barrier, your footings may need to be dug much deeper than on a level surface.

Why is the Frost Line Important in Construction?

When you’re building a deck, you need to make sure the ground isn’t going to shift under the weight of the structure. If the soil underneath the footing freezes, the expansion of the frozen soil can lift the footing and everything on it up into the sky. This is called frost heave, and it can cause serious structural damage to your deck if left unchecked. An engineer should inspect the site before construction begins to determine whether there’s enough room for the footings to remain stable. A professional contractor should also check the stability of the area before beginning work.

What Happens When the Soil Freezes?

When the weather gets cold enough, the ground will begin to freeze. As long as the air temperature is below 32 degrees Fahrenheit, the soil just beneath the frozen layer at the top of the ground will start to freeze. That means that the soil just beneath the freezing layer at the surface will also freeze.

Water expands by 9% when frozen. This extra volume is then pushed upwards into the air, not downwards into the compacted soil below. The liquid water in soils is usually in layers, much like a sandwich has different layers of meat, cheese and tomatoes. Each layer of water transforms into an ice lens within the soil. As these lenses form, they push the lenses above them higher up into the air, creating frost heaves. Frost can easily push soil up 6 or more inches.

How far do you have to dig to get below the frost line?

Frost lines are a safe zone for plants and other living organisms. Anything below the frost line will stay warm enough to survive. Plants need at least 10 degrees warmer than the air temperature to grow well. If there is less than 10 degrees difference between the air temperature and the soil temperature, then the plant cannot grow properly.

How deep do you have to dig to get below the frost line?

Why do footings need to be below the frost line?

You should dig your footings deep enough to reach the frost line. If you don’t, then the ground beneath the footing won’t be insulated from freezing during the coldest months of the year. Digging deeper allows you to get the footing closer to the foundation wall. This helps prevent water from seeping through the footing and causing damage to the foundation walls.
