Has anyone used these footings before?
I have a deck to build and they look like a good alternative to concrete footings with a bigfoot base.

It's the first time I've seen them. It looks like the key is that the 4" PVC has to be buried completely except for about the top 3"-6". That allows the compacted soil around the pipe to provide the rigidity to prevent buckling. Pretty cool solution - at $32 each (plus the PVC pipe) they'rer not cheap but they would be a lot less hassle than pouring concrete and setting post bases.

I'm thinking of building a play structure/house for my grand children. This could be a nice solution for the foundation. OTOH, with the site I have (almost pure granite rock) I can probably get by with just a few precast concrete piers.

If I had to work with a frost line condition or soft I would be very interested in this product.

Concrete has mass to hold the structure down, what's holding those structures. Not sure I would use them in a windy or high earth quake zone. What about the bending strength. Wonder how many building departments have approved them.

Personally I think a sono-tube is fairly easy and more commonly accepted. Like William I am curious how building dept. view them - but if your deck doesn't require a building permit you might be OK.

I'll ask the inspector about them. It's a low deck, no more than 4' to the top of it from grade. By the time you buy the big foot bases, tubes and cement, I think they might be cheaper. Thank you for the responses.

They may be ok for a shed ,deck.

I am not sure. Mixing and pouring the concrete tends to be the easy part compared to the post hole digging. The advantage would come in not waiting for concrete to set up and build the deck/shed the same day you set the posts for a small project. The cost would be close to the same if you are needing to use a SonaTube. If there is a frost issue then I think this tube would win due to the depth of footing and quantity of concrete. I only need to go 12" below grade in my climate.

[Allen42acj]

We have to go 4' below. I have a small backhoe so the gigging is easy enough..

I'm doing a full scale model at my house...

There appears almost nothing to resist a bending moment and only the backfill to resist uplift. Quick for sure perhaps for a shed or low deck.

Allen, please read this book regarding your window install.

Unless that layer of house wrap is being covered by another full layer of house wrap and rain screen, you are inviting water inside the walls of your house.

There are many reasons I see why this sort of product won't be advisable for your situation. If it was a deck that was maybe 12-20" off the ground - perhaps. You have a very different condition it appears.

Quick, easy, non-invasive, and reasonably priced...these are what I've started to use.

Excavation is almost never necessary, the small machines can fit through a 3ft. door, the pier can be taken back out and moved if necessary, the list goes on. That Redi-Footing looks questionable at best.

Alan
I'm going to make sure to use a tape. The windows I ordered have a J channel built in too.

Michael, I have seen those before and hey look good.

After looking, pretty sure I am just going with a footing base and tube to pour concrete.

Thank you all for the responses...
