Concrete piers in 55 gal drums support I beams

Hi,

I am looking at a 25 year old house. The house is supported by piers made from 55 gal drums filled with concrete and on top of these sit I beams.

The house is a three bedroom ranch in upstate NY and would get plenty of snow.

The house and floor seems straight and does not seem to have sagged.

Seems to me this form of construction is very make shift or make do. I was wondering has anybody used this concrete pier drum method or seen it? Is it absolutley crazy?

The house has a half basement. These piers support the house about 3 feet on one side and about 5 feet on the other. The I beams run the full length of the house. They are big I beams seems to me. Maybe 12" or 14"

Thanks,

Dean

If your main concren is just the foundation/piers, get an engineer and not just a home inspector.

A home inspector is a generalist looking for problems when a specialist (structural, roofing, electical, heating) is needed to assess a specific are of concern. Few home inspectors are qualified on special areas.

I am a home inspector and an engineer, so I can say that. If you look at structural adequacy, you look at the details differently than a home inspector.

Well, those are some honkin' big piers. The fact that they're in 55 gallon drums doesn't concern me. That's not really any different than using cardboard sonotubes. What concerns me about this is how is the craftsmanship? Seems to me that someone that uses barrels for piers is either super-creative or super-*******.

Are the piers situated deep enough to avoid frost heave? Here that is 36" and I assume it is much deeper in upstate NY.

Whether or not the size of the piers and the quantity of piers is adequate is something we can't tell you for sure. An engineer should be retained to do that. Variables such as the soil's bearing capacity, compaction, drainage, and the actual loads of the structure all must be considered to tell if this is any good.

Things that would turn me off would be very few piers, or lack of burial depth. It takes a lot of piers to support a home, and large piers spanned by steel beams isn't necessarily better than numerous piers and smaller beams of steel or wood.

If there aren't signs of settlement then that is a good thing.

Thanks I appreciate the views and the information. I will get a house inspection if I decide to procede further. I did not look at the foundation and beams long enough to check the number of piers or the depth of the piers. It would be useful for me to do even that. The house looks and feel very firm and the surrounding ground is stable and not built up. I'll take another detailed look. Thanks again I appreciate your thoughts.

So there's no basement, just a crawl space? Otherwise how would you know about the barrels right? Upstate NY should be 48" min below ground level for frost line. I have seen movement even at that depth in clay soils up here. Also crawl spaces are bad for cold air infiltration and frozen pipes up here.

It's a half unfinished basement that then becomes a 3-4 feet crawl space following the slope of the land.

I realize that in theory the drums that form the concrete piers could work fine and the I beams are probably sufficient.

BUT I did not get enought information. I did not see how deep the footing for the pier is, I did not count the piers and the distance the I beam spans. Nor did I get the size of the I beam. I really did not get enough information.

So I will have to take another look and probably get a professional opinion. The house needs a lot of work. I am trying to determine if the work is worth doing on the foundation that exists.

If this place is 25 years old and you don't have any sagging, cracks opening up in the dry wall, no floors separating or cracking open, no settling on one side or the other i wouldn't worry about the pilings its on or how the drums might look,, Using barrels is no different them sonotubes, In all actuality they are better for the simple fact sonotubes don't come in that big of dia,, the barrels give you a larger foot print, a little over kill maybe,, but i can say this, a friend of mine who i helped build his place, he never had any settling, heaving, no cracks in the walls, no problems with the floors, doors or windows. we welded to 55's end to end to get down below the frost. set em down in the hole poured in a foot of concrete in the bottom and built from there,, i can be a particular as oh billy hell, seen to many place's so warped out of shape you had to fight to get in the front door and then god help ya getting it shut, or even opening a window.. like i said earlier if your not having any of the problems i mentioned above,,

Barrels are unusual, but not unheard of. I have worked on commercial and industrial projects where the building was founded on drilled shafts, typically considerably deeper than a 55 gallon drum would be, but same idea. If you decide to pursue the house, I recommend you hire a local professional structural engineer with foundation experience to make a complete assessment of the structural condition of the house prior to making an offer. Ask for a written report, and expect to pay a reasonable fee (more than an inspector would charge).
