Shallow Foundation Puns

Half of the articles I read have no insulation under the slab so that the heat leaking out of the building heats the earth below. The other half have up to 18 inches of insulation underneath the slab. I don't understand how these two completely different techniques are both called FPSF. I think that letting your building heat the earth below it is just about the dumbest idea for a build trying to increase comfort and reduce utility bills/dependency.

I understand that building codes and techniques are stuck in the stone age and incredibly slow to adapt, but is there a coherent spec for building tight and insulated buildings in frigid northern climates? Do I need to apprentice in Finland to find ideal wall/floor/ceiling assemblies?

I recently purchased a home with a crawlspace in the SE United States. There is a significant amount of standing water underneath the vapor barrier in my crawlspace after it rains. There is soil erosion around the perimeter of the crawlspace. I have exposed footers in some locations.

3 crawlspace companies recommended an interior french drain to sump pump system. I also contacted a home waterproofing company who after an inspection STRONGLY advised against an interior french drain system. Their rational being as follows:

"One really big reason that interior trenching would be a huge NO-NO here is the fact that the wall-footings are quite shallow in places. Trenching on the inside of them would cause a structural undermining and almost certainly cracked footings. That’s why we’re proposing Exterior Waterproofing only and not offering Interior De-Watering as an option."

Their water proofing plan was 45k...

I've contacted two structural engineers; one doesn't seem concerned and the other only had slight concerns if the footers are <12" deep (which they are) Neither SE has been onsite.

Can installing a french drain system damage my footers and comprise my foundation as the waterproofer states? Do I listed to the waterproofer or the crawlspace companies?

TL;DR: Can installing an interior french drain system damage my footers and comprise my foundation since I have shallow footers?

I live in a cold climate and want to add a wood workshop on the back of my house (about 1000 sq. ft.). I’m looking to keep the building heated with Reznor space heaters and ventilated with continuous dust filters and an exhaust fan.

I live North... like mid-Canada North and it gets legit cold here. Has anyone used the FPSF details for an on-grade foundation? How did it work out?

Secondly, is it actually significantly cheaper than a traditional foundation with footings below frost line? I’m looking at a 5” slab, plus the expanded corners and EPS insulation.

For those that don't know, there is a popular idea that everyone has one, or a combination of, 5 a "Love Languages" that represent how people show love. They are as follows: words of affirmation, acts of service, quality time, physical touch, and giving/receiving gifts. I think there is some validity in this idea, people show love in different ways, but "gifts" is fucking childish and if that's your love language you will be burning through partners for the rest of your life.

So I'm still reading foundation, but so far the characters in the book are just so vain and think they know everything. Is there character development or any developed characters when the book series progressed. Also side note this is my first Asimov book so please don't spoil or reference his other works because I know his robot series ties in with the foundation series.

Ive been doing some reno work in my 1970s home with walkout basement. I have since found that the foundation isnt properly stepped down below frost line for the walkout basement door. The footing is only down about 8 inches under the door. Ive noticed some cracks on either side of the foundation wall underneath the door.

After noticing this I dug down and put 4inches thick of XPS foam on the side and top of the footing. I have since been reading that this isnt enough and you should have wings that extend out 48" from the house. At this point the ground is frozen so I wont be able to do that until spring. Im worried about frost heaving doing further damage to the house.

Normally I wouldnt be worried any more about this than I would have been in previous years as this has been like this since the 70s. My concern is that I have also went from 1inch beadboard to 2" of XPS on the inside of foundation walls as well as R+ dricore on the floor. Finally to top if off I moved my retaining wall back from the door (was causing rot around the door) about 1 foot on recommendation of a general contractor before I knew the foundation wasn't stepped. This would expose another 12 inches of foundation wall to the elements.

I guess what im wondering is if there anything I should do to mitigate further damage this winter, ie: keep the basement well heated until spring, remove dricore around door? heat tape? Or not worry about it at all?

edit: air freezing index in my area is 1500

I have this question:

A new factory building needs individual square pad foundations to support the steel columns, which are to be founded at 1.25 m below the ground surface level. Each column carries a load of 900kN. The ground consists of a firm clay (cu = 90kN/m2 , yd = 18kN/m3 , ysat = 20kN/m3 and mv = 0.06MPa-1 ) and this extends to great depth. The groundwater level is 0.5m below the ground surface. Use a factor of safety (load factor) of 3 against bearing capacity failure. Determine the size of pad footing required to support the columns with respect to bearing capacity failure, and also calculate the long term settlement of the footing.

I can't seem to find an answer for the dimensions (length B=L)

I started with:

q safe = P/A = 900/B^2

q safe = F.Cu.Nc.Sc.dc = 3 x 90 x (pi+2) x 1.2 x dc

900/B^2 = 1665.4dc

B^2 dc = 0.54, where dc = 1+0.23(D/B)^0.5 , where D=1.25

this leads to some long, complicated maths that isn't the standard for this module, and is far too much work for the amount of marks this is worth.

Clearly I'm approaching this the wrong way or I've made a mistake in my maths, can anyone help me out? There is absolutely nothing in all my lecture notes to help me, and my lecturer is extremely ill at the moment so can't help me for my exam next Tuesday.

>A surprisingly good tactical shooter that reminds of classic Rainbow Six games. Its gameplay faults are easy to fix, and you don't have to guess if it'll have a good post-release support.

im just curious if anyone has personally used this style for their foundation at all.
