Dry Set vs Wet Set Fence Posts – Which Is Better for Your Fence Installation in Chattanooga?

If you’re planning a new fence installation in Chattanooga, Ooltewah, or anywhere in North Georgia, one of the most hotly debated topics is how to set fence posts—should you use the dry setting method or wet concrete setting method? Homeowners, contractors, and DIYers all have strong opinions.

At Top Rail Fence Chattanooga, we’ve installed hundreds of fences using both methods—and here’s the truth: both dry set and wet set posts offer nearly identical long-term holding strength when done correctly. The key is in the technique, not the mix.

What Is Dry Setting Fence Posts?

Dry setting (or dry packing) means pouring dry concrete mix (such as Quikrete) directly into the post hole, around the fence post, and then adding water after the fact. This method allows the concrete to set in place without premixing.

Steps for Dry Setting:

1. Dig post hole (usually 24–36″ deep)
2. Set post in place with gravel base
3. Pour dry concrete around post
4. Add water slowly in layers
5. Allow concrete to cure naturally over 24–48 hours

What Is Wet Setting Fence Posts?

Wet setting means premixing concrete in a wheelbarrow or mixer with water and then pouring the wet mix into the post hole. The post is then leveled and held in place while the concrete cures.

Steps for Wet Setting:

1. Mix concrete to a thick but pourable consistency
2. Pour into post hole
3. Set post into wet concrete and level
4. Brace or support post until concrete hardens

Dry Set vs Wet Set – Side-by-Side Comparison

1. Holding Strength

• Both methods provide the same PSI strength when cured
• No major difference in long-term durability

2. Speed & Convenience

• Dry set is faster for solo installers or small crews
• Wet set requires more prep and cleanup

3. Weather Conditions

• Dry set works better in dry weather with no rain in the forecast
• Wet set is more predictable in damp conditions

4. Post Alignment

• Wet set allows more immediate adjustment
• Dry set may shift slightly if not held in place

5. Cost & Labor

• Dry set is slightly cheaper (no mixer needed)
• Wet set requires extra tools and time

Do Fence Posts Last Longer with Wet Setting?

Not necessarily. The lifespan of your fence post depends more on:

• Using gravel at the bottom for drainage
• Keeping the concrete above ground level to avoid pooling water
• Choosing treated wood or metal posts
• Ensuring the concrete fully surrounds and supports the post

Best Applications for Each Method

Dry Set Ideal For:

• Small fence runs (under 100 feet)
• DIY or one-person crews
• Quick backyard repairs or extensions

Wet Set Ideal For:

• Large-scale projects with multiple installers
• Commercial, pool, or HOA fences requiring precision
• Heavy gates or decorative steel fences

Our Recommendation: Choose Based on Your Project

At Top Rail Fence Chattanooga, we use both methods depending on the project scope, soil conditions, and timeline.

For example:

• A vinyl privacy fence in Ooltewah with soft soil? We may wet set.
• A ranch-style crossbuck fence off Snow Hill Road? Dry set might be faster and just as strong.

Both techniques, when done right, will anchor your posts solidly for decades.

Dry Set vs Wet Set – It Doesn’t Really Matter

Despite the heated debate in DIY forums and among fence pros, here’s the bottom line:

Whether you use dry set or wet set concrete, your fence posts will be secure, level, and long-lasting—if installed properly.

Don’t overthink the method. Focus on proper hole depth, quality materials, and experienced installation.
