PostShield

Pole Barn Guru Blog

Hansen Buildings is always looking for new products or techniques which could be incorporated into our pole buildings to offer clients a better product. One resource we utilize is to monitor websites of others who provide post frame buildings, whether constructed or DIY (Do-It-Yourself) building kits.

In checking out one of these sites, I found this offering:

post shieldPostShield protects your barn’s posts against rotting with a layer of modified asphalt. A durable film layer protects the asphalt. The specialty-formulated adhesive self-seals around nails, crews and other punctures. For a very small investment, PostShield can add years to the life of your pole barn!”

Sounded pretty exciting to me, so I wanted to know more! Going to the PostShield website I found:

PostShield, is a UV impregnated PVC ‘sleeve’ that makes installation, replacement and repair of 4×4 wood posts simpler, faster and safer. It extends the life of posts used for signs, fences, retaining walls…anywhere a 4×4 wood post is used. PostShield is being used by homeowners, fencing contractors, State DOT’s, Parks & Recreation Departments and CalTrans. 

PostShield helps prevent decay and extends the life of wooden posts by creating a barrier between wood and dirt, draining water and venting moisture.

Post replacement becomes quick and easy and you will no longer need to dig out old concrete. Simply pull the old post out of the existing PostShield and slide a new one in. PostShield is a simple, cost effective solution for prolonging the life of wooden posts.”

In reading further on the Post Shield website, it turns out they are ONLY available in one size – to fit a 4×4. Now, other than perhaps for an entry door post, I would hope no one is offering post frame buildings with 4×4 columns!

Apparently the PostShield patent covers a myriad of sizes, however if sizes to fit typical pole building post sizes were made available, for use in pole barns, I see some potential structural concerns.

“The design of the PostShield allows the post to “breathe”. Specially designed ribs on the interior surfaces, the ones that come into contact with the wood 4×4, allow moisture to evaporate away from the post.”

PostShields are placed into concrete in a hole. The idea is to be able to slide a post into the PostShield, with fasteners at the top – into the post, being the only thing resisting wind uplift. It would require a significantly large number of substantially sized fasteners to be able to resist the uplift forces generated by a building of any significant size.

 

The idea here for a pole building – is that there is a binding value (which can be calculated by the way) between the concrete and earth, and then between the concrete to the post, to create the foundation….and hold the pole building in the ground.  I may offend a few here, but I have to say it…putting a plastic sleeve around a post so it “easily slips out” is like putting a post condom on it.  Talk about negating why you are putting poles in the ground in the first place….to create the foundation.  I have the same opinion of sono tubes – but that’s another day and another blog.

My real issue – why even mention a product as being available, if it is not applicable to the end use?
