We place 1-3 inches of tamped paver base at each location requiring one-half to one bag of gravel each. The county building dept has requirements for your area.They know.Great alternative to concrete block! Just finished a 30 x 40 ground-level deck around an above-ground pool. Does this sound about right? seems pretty far down. I went off of a chart that compared the Air-Freezing Index to the frost depth. Speaking of frost, how do you determine the frost line. Not sure what is allowed in your area.To me, the footings and piers, and the roof are the lifeline of any dwelling.If I was concerned with any frost heaves, or perma frost in ak, I'd put out the money to buy a 12' piece of coil rod from a const.Supply(1-1/2x 12')cut it in 16" pcs, and have a welder (certified) weld beam pockets on top of the 16" pcs Apply on each pc, a washer nut made for the coil rod, and one plain heavy duty nut.In your sonotube pier,during the pour, install an 18" pc of abs or pvc, 18" with duct taped ends to the center of your pier in the pour.Before installing the brackets in the pvc,put a 6圆 plate washer on top of the pier hole.The amount of piers depends on your cabin size.Now you have the cabin built on these steel rods(65000) strength lode, and any shifting your cabin may do can be corrected with a pipe wrench.If it would make you feel better, you can always shim each beam pocket after leveling the place,just remove the shims to re level.Install camp trailer levels to each side and you have it whipped. But also check with the local building officials and see what permits you might need and what building codes they use and enforce. Then the house loads are known and only then can a proper foundation be designed. Set the size, height, loft or second floor, or not. Don't start designing from the bottom up right away. I would suggest that as you develop your plan you show, talk and ask questions about it a lot before building. There are a few things he has promoted that one should really take long hard looks at, if one wants a long lasting, safe home. You've not done this (build from scratch) before I suspect. Quoting: ceiling(terrible first impression) ![]() I don't expect that building to last as long as my cabin, which will be on a full spread footing per my permit. I built a small A frame to keep snow off a pop up tent trailer, and on the two sides I placed piers on dirt every 30 inches or so, to distribute the weight as evenly as possible. Now your bearing point is below the freeze and thaw cycle. One solution to this, again, legal or not, is to dig 12" holes as deep as the frost line, fill with wet concrete, and wet set the piers in the concrete. Ten years later they are no longer in a horizontal straight line and your building is out of whack. Just placed on the ground they are above the frost line, which means the soil under them will freeze and thaw, freeze and thaw. The problem with using pre-cast piers for a foundation, legal or not, is stability. ![]() IMO, something that large needs a proper foundation in the interests of long term use. As I said, the areas I know, will not permit deck blocks for a residence, but I don't know them all.Īlways best to begin with checking the local agency. If you skip that and just go ahead and build, and IF the deck blocks do not meet code, then you will have a lot more trouble and expense than if it had been checked and done to code. I would check with the county or whatever authority has jurisdiction over building permits. The areas of CO I am familiar with have some fairly strict building code adherance. What are some thoughts on this? Is it safe for a long term cabin?įorget to mention, the cabin will be 25x25. but he used deck blocks for his foundation.
