Treatment for Bamboo Poles Buried in Soil

Treatment for Bamboo Poles Buried in Soil

I have a question regarding bamboo treatment. I want to use bamboo poles as structural elements in my ranch but we have water sprinklers to keep certain crops fresh all year. How can we treat the poles in order to keep it in use at least 6 years buried in soil inside the wet ground? Poles will be buried 3 ft in the ground.

Would the bamboo lose strength with time? How do I preserve and extend the lifespan of the bamboo? What would be the lifespan of the bamboo after the preservative treatment? I was thinking to use busan 1009, do you recommend it? Thanks for your comments.

Generally speaking it is not recommended to use bamboo buried in soil for structural purposes. You could use chemicals to extend the lifespan for bamboo buried in soil, but just as most timber, bamboo will eventually deteriorate even if chemically treated.

I have no experience with busan 1009 but what we use to protect bamboo poles in ground contact is tar. Tar or creosote isn't exactly an eco-friendly product but it is cheap and does provide excellent protection. I recently dug out some bamboo fence posts treated with tar and they were still in tact after 10 years.

The best way though is to chemically preserve the bamboo poles and to design a structure where the bamboo poles don't touch the soil directly. A concrete foot or large rock for example would work great.

Thanks Stephane. There is no way to make concrete foundations. We are talking about agro-industry. So, we have a lot of hectares where we want to use bamboo poles. TAR is in spanish = Chapopote?? A black oil??

Tar in spanish is "Alquitrán". To dissolve the solid tar you can mix it with gasoline.
