For much of the 20th century treated pilings, poles, and posts underwent specialized pressurization that impregnated the wood with chemicals to protect it from pests, rotting, and moisture damage. All three of which were common problems in marine-style environments. In the 21st century, there’s been a discontinuance of some of the more noxious chemicals that were using for treated pilings, and the market instead introduced newer, more eco-friendly preservatives. This has enabled treated pilings, poles, and posts to retain the following top advantages in addition to being overall good for the environment:
- Longevity: Treated pilings are capable of resisting damage by moisture intrusion, pests, and fungal decay for several decades. You can use them in scenarios like bulkhead construction and submerge them into sea water without fear that they’ll quickly succumb to the elements. Certain grades of treated wood pilings when combined with a concrete cap can even last over 100 years. That’s a great return on your investment.
- Economy: While treated pilings might initially be more expensive that traditional lumber, their longer lifespan and low maintenance will equate to much lower costs in the long run. Additionally, treated pilings, poles, and posts are much cheaper than their alternatives, including concrete and vinyl, making them a wonderful happy medium and cost-effective choice.
