Re: Wood Foundations


Here is a video of the prep and installation of the Superior concrete walls.

I see what they did in the video. They pound some rods in the gravel and check each one with a laser level. Then use that to run their screed board on top of. Good idea.

Re: Wood Foundations


I recently got roped into doing a wood foundation (I pushed hard for concrete but no go)

Does anyone have the best building method for it? Sadly in my area no one puts in perimeter drain either :|

Re: Wood Foundations


Proper drainage.
Correct wall stud strength.
Proper backfill.
Proper floor connections to both lower and upper foundation wall plates.
Proper exterior wall waterproofing.

I prefer footings for walls.

Re: Wood Foundations


Wood basements are just another version of Lessor substitutes, similar to oldenfeild tile, and other products that just don't last, but are a few percent cheaper at the beginning...IMHO

Does anyone trust 40 and 50 year wood shores in wet Mines?

What bank would loan money on a 40 year old wood basement?

Can You imagine your grandkids living in your home with a wood basement?.

Eventually the preservatives will wash out, first at the always damp, but above the water table, most bioactive level of soil(see hundreds of years of rotten fence posts and wood pilings experience).

Yet many of the best practices of masonry foundations apply to 'Temporary' wood foundations....

If you can have 100yo wooden boats, you can have 100 yo wooden foundations.

Re: Wood Foundations


I would not have a problem with a wood basement
the right drainage, waterproofing and backfill the wood really should never see water
all those things should be done on any basement
what about all the wood pilings out there?
they last over 100 years, will last forever if they are filling submerged in the ground water

If you have 100 yer old wooden boats - they damned sure weren't in the water for 100 years.

Re: Wood Foundations


I'm going to do a scientific experiment here - because hdavis brought up a perspective.

I will place a 4 x 4 x 1 ft hunk of wood in the ground, where periodically, it will be exposed to moisture. I will do the same for additional hunks of wood - some coated in tar/bituminous, some in plastic -- in fact, one each with every water proofing mechanism currently used.

I will also place a 4 x 4 x 1 ft hunk of concrete in the ground. And I won't do a damned thing to protect it.

Nothing nada. zip. zero. zilch.

Next, I will fast forward the time machine 100 years. During that time span, I will subject every sample to the injustices of life - ground movement, accidental damage due to, oh say, the sprinkler guy, or the sewer guy, or the gutter guy, anything that can be imagined.

Now I stop the clock and examine the samples.

At the end of 100 years, I already know I will still have that 4 x 4 x 1 ft hunk of concrete. In fact, at the end of 100 years, that concrete will actually be stronger than when it was formed.

And no one can make that guarantee with any of the wood samples.

Re: Wood Foundations


Ignoring the Roman's version of concrete and some of the new expensive mixes not generally used, submerged wood lasts longer than submerged concrete.

Wood won't crack with minor movement the way concrete does.

In theory that is true,however,the 100 yr. boats are periodically removed from the water,re caulked,painted and any rot replaced. Furthermore,I would guess the wooden boats were made from white oak,not chemical laden glued together (plywood) southern yellow pine.

Even old Iron Sides sees dry dock for repairs.


Big difference, with no empirical data to support the theory,not apples to apples.

Re: Wood Foundations


I think one can easily connect the dots and extrapolate the similarities of degradation of metal fasteners explained in this article by a marine surveyor, and the same failure in oxygen starved environments with wood foundations.

Oxygen starvation is a ways down in the article,be patient.

Re: Wood Foundations


In case you didnít know; accelerated laboratory testing of modern pressure treated materials indicates a lifetime of over 100 years with no serious deterioration, and the durability of the systems has been amply demonstrated over the long-term by in-ground tests conducted over the past 40 years by various Federal agencies.


Sorry,can't give it too you,"accelerated laboratory testing" is a far cry from empirical data / knowledge.

Agreed. Not piers, not boats, not submarines, not decks. Honest to Pete residential structures erected by mere mortals, in real life, in actual **** ing conditions.

Oh and discussed in a herb free environment - and I def think some here have been toking over the line.

I'd use the word blarney, but that would a disservice to the Irish.

Accelerated testing data IS empirical data.

Re: Wood Foundations


Public perception is important. If people lose faith in the concept of Wood Foundations then resale, insurance and refinancing would be a problem.
