How deep should dock posts be buried

Dock Post Depth Guidelines

Ahoy there! If you're planning to build a dock, then you must be wondering how deep should dock posts be buried. And let me tell you, it's an excellent question! The depth at which you bury your dock posts will have a significant impact on the overall stability and durability of your dock.

First and foremost, the depth at which you should bury your dock posts will depend on the type of soil you're dealing with. In general, if you're working with dense, compacted soil, you'll be able to get away with a shallower post depth. However, if you're dealing with loose or sandy soil, you'll need to bury your dock posts deeper to ensure that your dock remains stable.

In most cases, we recommend burying your dock posts at least three feet deep. This depth will provide enough stability to withstand the weight of your dock and any boats or watercraft that you plan to park or moor there. However, depending on the type of soil you're dealing with, you may need to go deeper.

For example, if you're building a dock in an area with loose, sandy soil, you may need to bury your dock posts as deep as six feet. This depth will ensure that your dock remains stable, even during heavy winds, waves, or currents.

Another factor to consider when determining the depth at which to bury your dock posts is the height of your dock. The higher your dock is, the deeper you'll need to bury your posts to ensure that it remains stable. In general, we recommend adding an additional foot of post depth for every foot of height above the waterline.

In addition to the depth at which you bury your dock posts, it's also important to consider the type of posts you use. For example, wooden posts will rot over time, which can compromise the stability of your dock. On the other hand, steel or concrete posts will last longer and provide greater stability.

When it comes to building a dock, there are a lot of factors to consider. But one thing is for sure: the depth at which you bury your dock posts is critical to ensuring the stability and durability of your dock.
