Why don’t wooden piers rot?

Wooden piers are undoubtedly a scenic and functional addition to any waterfront property. However, one may wonder about the longevity and durability of these structures when exposed to constant water and moisture. Surprisingly, wooden piers are remarkably resistant to rot despite being submerged in water for extended periods.

If you’ve been curious about how wooden piers can withstand rot in the water, this article will explore the reasons behind their resilience.

1. Type of Wood

One of the major reasons why wooden piers don’t rot is the type of wood used. For instance, hardwood varieties like oak, maple, and teak are used to build piers since they have a high resistance to rot and decay. This is why they are commonly used for boat building and outdoor furniture as well. The choice of wood also depends on its durability, stability, and density, which are essential when dealing with water and weathering.

2. Treatment

Another significant contributing factor to the durability of wooden piers is the treatment they undergo. Wood is a natural and porous material hence, it’s imperative to protect it from water and moisture. This is typically achieved by using treatments such as pressure treatment, borate, or creosote. These treatments help preserve the wood and make it more resistant to decay, insects, and fungal growth.

3. Proper Ventilation

Another reason why wooden piers don’t rot is proper ventilation. Wooden piers need to be well ventilated to allow any moisture to escape, which reduces the likelihood of rot. Building codes and professionals regulate ventilation to ensure adequate circulation, which also helps with deck maintenance by keeping it dry.

4. Regular Maintenance

Regular maintenance is also crucial to ensure that wooden piers don’t rot. Inspection, cleaning, and staining help to preserve the wood and protect it from the elements. Over time, boards may warp or split, compromising the integrity of the entire structure. Regular maintenance helps to identify such an occurrence promptly, which means they can be appropriately repaired or replaced before causing more extensive damage.

Wooden piers don’t rot due to a combination of factors such as wood type, proper treatment, proper ventilation, and regular maintenance. These features help to preserve the wood and enable the structure to withstand exposure to water and other external elements. By taking good care of your wooden pier, you can enjoy it for many years to come.
