BUILD A HOUSE {the next step)part 2

By
Home Inspector with Elliott Home Inspection

Well here we went and demolished the house so what is next?

Time to pour what is Known as footings,which is the very bottom part of the stucture or foundation.

How important is it to keep this level.?

did you know this is normaly twice the width of the cement foundation that will sit on top of it?

Why do you think they pour cemment for this seperate from the walls that will sit on top of it?

Why is there a line going down the middle?

Any body Know?

Com "on guys put your knowledge too good use other than cut and paste for points!

 

Sure beats doing it with a shovel Wonder what the gravel is for?

Note; The footprint of the footings.They tell a story

Why is it two different colors?

gravel

Guess they will not need that any more

Is there a concrete encased electrode in the footer?

Know how much you love electric.Do not beleave they buried one as it would not be to common around here yet,but sure will try to confirm one way or another just to be safe.(safe as a ground rod that is).

For any one not familiar with the term concrete incased electrode AKA (UFER ground) is a ground that literaly gets incased in the cement footing as the cement is poured over it.

Mike since as home inspectors we do not normily verify something like this could you tell me what I should look for?.

Will it have something like a ground rod exposed out of the footing.You got me on that one.

Yes. Start at 250.52 NEC

3) Concrete-Encased Electrode. An electrode encased by at least 50 mm (2 in.) of concrete, located within and near the bottom of a concrete foundation or footing that is in direct contact with the earth, consisting of at least 6.0 m (20 ft) of one or more bare or zinc galvanized or other electrically conductive coated steel reinforcing bars or rods of not less than 13 mm (1⁄2 in.) in diameter, ........

Brad why pour the footing seperatly. Couldn't they eliminate  the problem all together by pouring it as one unit.Maybe something with tension and compression? Here is what I mean.

Mike to dry for easy understanding as I wish to take away all mystery that makes it hard for most.

I am aware of the NEC but most folks reading need easy laungage.

NEC states what you  and I just said but have you ever seen a UFER physicaly your self as I have not.

When it comes out of the footing would Imagine it is at least coming staight out of the cement floor in the basement and looking like a outside ground rod.

Wonder how long they last before they deteriorate.Once they do then I suppose you are back to regular ground rod.

Yes I have seen them.

A UFER is a little different then the concrete encased. But we know that.

I for one do not like the fact that copper is required to be in contact with concrete when we all know what concrete does to copper.

One of the reasons some of my post are vague is because I want people to get the right answers on their own.

I just hate to see the new inspectors reading things here or on another forum and repeating it as fact.

We all know that a lot of people read these comments and never engage in the conversation.

Hi Mike if you are not willing to share your knowledge I'm sorry for that ,as the whole point of build a House is to do just that.

I wish to take all of the mystery out of what goes on,and am not afraid that I will lose any future business to others buy being a teacher or a student.

Anybody who joins these forums thinking they know it will be the last people who worry me as competition since they are so full of themselves that it carries over as arrogance to their clients.

Mike you will notice I do some of what you suggested through the simple caption comments above my photos hoping you or someone with knowledge will jump in and share for the folks at home.

Why would you worry if they use your comments as fact if you are correct since that would also make them correct.?

Did you know that the wikipedia is based on the idea of people sharing what they know about their area of expertise thus making it one of the most popular sites in the world.?

I am a relative newbie to the internet,yet have learned so much thanks to many wonderful people who have shown patients with my constant ...................WHY?

In the words of Mike at Inspectors Journal   (one team one fight)

Mike....I checked with the crew today and they said they never use cement embeded electrode grounding conductors.

Which is pretty much what I thought but wished to confirm.

Thanks Brad at least I got to have fun with paint.

The foreman across the street is a nice guy and I could have asked him but would rather the members take care of it.

There are many things I do not Know the answer to off hand unless I look it up yet would like to have that knowledge with me at all times right in the brain were it belongs.

Very few people can say they know every stage of construction, but soon we all will.

It is very hard... not impossible to build a monolithic footing/foundation. Building a footing is easy, a trench, stone base, sides.

You then have a steady, flat base to set your foundation forms on top of.

Imaging trying to suspend the foundation walls over the footing, maintain elevations, keeping the concrete from blowing out, etc. So much easier to do it in two steps.

Copper in UFER?

Isn't simple re-bar the most common material used when constructing a ufer? I would imagine that rebar would last quite a long time.

Bob, Prior to spreading the gravel, did they grade the soil to a common drop, say for instance to a place that will be the future home of a sump pump. Anytime I pour concrete, inside or outside, I always pitch the soil to where I want the water to end up. Some folks simply level the gravel. I've come across cases where the most beautiful flatwork was done on top of improperly graded soil. The water runs off the concrete and right back under the concrete and right back into the building.

It's hard to tell, but are the stones two different colors because the light color stone is new crushed gravel and the darker color stone is recycled crushed concrete. Recycled stone is much cheaper, more conservant on natural resources, personally, unless someone tells me different, I believe is just as good.

By the way, did they put poly over the stone prior to pouring the concrete? And finally, if you are in a radon area, it may make sense to install a pvc pipe, originating from below the slab through the roof. If radon is ever in question, it is very easy to cut in an exhaust fan. I always recommend this. It is so easy and cheap to do it during construction and is a quick real fix to ventilate the slab in case of radon.

IT was just wet but good theory.

Did not see poly however right now it is a swimming pool.

That would have been a good idea.

Thank you for those questions, this is good stuff to know.

About the footing,and further thinking on that scale it makes sense.

This is not a toy model.Even what seems so basic ,took many men over long periods of time to figure out good practice.

Anyway, until then,
