I have gotten quotes on both of these options as well as poured wall options. I am finding that both are still cheaper then poured 8" walls, especially once you add 2" exterior xps and frame out the interior and insulate. So I am really trying to decide on the 2 systems. There is a lot of arguments about PWF. However it will never rot if they are protected...If I went with the SIPs, I would use a double layer of sealer starting with a 60 mil applied rubber and then the rubberized plastic product from Certainteed that protects it during backfill, plus allows for a better drainage plane and more water protection. The basement wall panels costs $17000 including the waterproofing. They are 8" panels with PWF 2x8 16" oc, 3/4" exterior PWF plywood and 7/16" interior osb skin. They sit on a 2x12 plate on gravel. Installation is not included and is DIY.
The superior wall system was quoted at 19,000, but this also included installation.
Does any one have any suggestions, pros/cons of each system? I am thinking the extra 2k is worth it for installation alone with the SW.
I was also quoted several ICF options, all of which were 8-10K more, plus we have to finish the basement, which we are not planning on doing just yet.
However I will add I got a price on TF ICF. I feel I can probably DIY the TF system and not the block. I see the bracing is more simplified and blow out chances are reduced. The TF plus concrete would be around $11,000, DIY, plus footings and garage stem walls. |

Have you considered a MgO SIP for below grade applications. They are becoming more and more popular in Western Canada and gaining ground in central and eastern Canada. I will be using the product for below and above grade application on my next home construction in the spring. Check Titanwall, they offer a good product for below grade application as you have described. The web site offers technical info and videos that portray the technology. Alot of people disregard MgO as a building product for some credible reasons but this company backs there product with a 15 year warranty, wich is more than most building materials. It is atleast worth a bit of time to investigate. If you call Titanwall, ask for Matt, he was trully helpfull in my project. How many square feet of foundation wall does your project require ? Good luck. |

TF systems is $1650 for the material alone? Or, does that include the concrete as well.

My house is built on a SW basement. So far i am pleased, but we still are not done. We spent 10,000 on 96 ft of ten ft high walls. I did sight prep. Feel free to call if you want details of my exp. seven zero four 779 9867 michael |

. There is a lot of arguments about PWF. However it will never rot if they are protected..
Where I was a contractor for several decades the "argument" was settled when PWF was banned.
I sure replaced a bunch of them for something that never would rot.
If you are ready to bet the future of your house on it then go ahead. I have no skin in the game anymore as I have quit contracting altogether, just hate to see people taken by salesmen who are unwilling to give a real warranty. Some of the wood foundations we replaced were not even a decade old. Your foundation should last as long as your mortgage don't you think! |

Telsa, howw does the PWF where made when you had to change them, second, what was the concentration of chimical of these PWF panels, how where thewy protected... I am very curious to know if the product is made the same way now then before soo we do not repeat the same mistake.. Thanks for the insight of your experience. Pierre |

Good questions and I would have to say there is not one answer for each of the numerous situations.
The jobs were almost all within one of the most stringently administered code enforcement areas I ever worked in and I have done jobs in several locations across the US and in several countries. From this I can conclude they passed code at the time they were installed.
More than one situation could be attributed to improper use of attachments so the code official was lax or otherwise motivated to look the other way. This happens with all types of building methods.
None of the jobs seemed to have un-rated materials.
There is a tremendous amount of ground movement in Central Alaska and I feel the stresses this imposes on a foundation were not fully understood in the 60", 70'S' 80'S 90's when I was current in the industry.
In all fairness we did a lot of concrete repair as well but it is still allowed.
Most of the subsidence I saw was due to the misconception a lot of people seem to have about what ultimately resists gravity loads. The concrete footing distributes the load over a larger footprint but the soil bearing capacity has to be considered. A lot of people seem to think you pour a thicker footing in poor bearing soils instead of providing a wider footprint.
For me, from what I saw, concrete is the better choice when all other issues are equal.
When I graduated from contracting to research (there is a God) we did poured concrete for $10 per sq ft. labor and material (Anywhere in Alaska)
CMU block was more at the time. I have no idea what the prices are today. |

I have to agree with you, in all the point, the PWF panels are good but you have to respect all structural conditions, and understand the soil bearing capacity, as you said wider is better than thicker, thicker increase the weight per sqare feet, witch is the opposite that we need, i have to agree too that for the same price, i would consider the concrete, but the confort of the PWF panels create in the basement is way over the concrete one, because of the insulation. The idea of the MGO board is from what i read everywhere, a better solution than the PWF board, BUT, quality and standardisation of the product have one of the worst reputation i ever read, soo, it is woth to look at it, but very very closely. I did not use it yet, but i want to....but i am afraid of playing russian roulette with that product. That is the bottom of my mind...i feel better producing PWF panels.
