all done

Looks like earthquake damage.
The first one, maybe a mortar.
Get it. A masonary joke.

Damage caused by failure to provide expansion space against poured concrete roof.

Roof is pushing parapet walls.

Just a guess--do I win a prize?--Mike---

 

[kwikfishron]

There's no more roof, mortar fire imploded it causing the damage on the corner.

Luckily though most of the gunner ports are still useable.

 

[oh'mike]

Come on back new guy---that second picture --the cause is is obvious that I'm going to let Kwikfishron answer that one--

 

[kwikfishron]

Well thank you Mike, the second picture looks like Termites to me.

 

[oh'mike]

Well thank you Mike, the second picture looks like Termites to me.

I would have had it wrong--

I figured one mason started on the left--another from the right---one guy used less mortar--

They didn't think any one would notice --so they left it like that.:whistling2:

 

[kwikfishron]

Glad I could help.:thumbsup:

 

[ConstructionFTW]

Ok thanks a lot guys. The second pictures is caused by termites, I got it.
What about the first picture? I know it's not caused by earthquake as earthquakes are not so common in the place where i live. so please just give a few explaination about the first pic so i can write about it in the report.

kwikfishron, oh'mike and Ron6519 thanks a lot. :thumbsup:

 

[oh'mike]

My answer was correct on the first picture---concrete roof expanded and pushed out blocks--

Second picture---footings dropped.

Thanks a lot sir. One more question please:
what are the CRACK REPAIR METHOD for this kind of cracks as you can see in the first picture?

 

[CplDevilDog]

A mortar

 

[oh'mike]

Remove the parapet--add expansion material along slab--(foam or fiber mat) then rebuild parapet.

FTW---you would get better responses if you offered your own solutions
and let us tell you if the solutions are correct or not.

How are you going to rectify the bottom picture?---Mike---

 

[Red Squirrel]

Slap some parging cement on it, put it up for sale and hope it sells before winter. :thumbup:

I'm a little horrified that you're doing research for a college project on an internet chat room.

Please go to the library and research this book:

Geotechnical and Foundation Engineering: Design and Construction
Robert W. Day
McGraw Hill, 1999

Chapter 7 has some good information on cracking, and has even more resources annotated throughout. But regardless, don't lie. I'm almost half tempted to let you in on the joke interpretations sprinkled in the suggestions so far, but you should research it all and get solid sources yourself before you look like a fool when you turn your paper in.

Believe me, many college students think that "copy & pasting" from websites qualifies as research & writing.

I think i will be using "Crack injection with epoxy" ?

No, beleive me I'm not going to write everything which is disscussed here. I went through many sources (almost finished the report) but I had some doubts about the reason behind the cracks which i couldn't understand thats why i came here to ask to clarify it to myself.

anyways thanks all !!

Actually there is a lot more information available online that there is in any library. Internet sources are perfectly acceptable as long they are verifiable and you site your sources in the correct format (APA,MLA). The book suggestion sounds like a good one though.

As far as the second crack solution I would guess you would need to resolve the footing issue unless it has stabilized then you could seal the crack with hydraulic cement.
