how do u calculate this?

joasis 06-03-2006 10:02 PM

math works can go the long way...wall length X height = square feet, then the .88 sq/ft/per block.....- windows, doors, FO's, and allow for corners.

im having a 9x10 garage door and a regular walk-through door? how would i calculate that?

Glasshousebltr 06-04-2006 10:24 AM

Knock off 90 for the garage door and 20 for the entry.

49 sticks of vertical rebar 32" OC in filled stretchers, filled corners.

I'd start with 100 bags of 50lb morter and figure my use for a second delivery.

Because your headed up 15 feet, it might not be a bad idea to use block wire.

so that would be 2090 thanx :) and by the way i got my floor poured for my garage yesterday i gotta give it time to set and it was pretty warm last nite lol it should be ready to set blocks on by tomorrow or tuesday

You'll also need to add more blocks if the 15 feet height you mention is the finished height above grade.

Remember that you need 6 more courses or more below grade depending on frost depth or whether there will be a basement below the structure.

Chuckman 06-04-2006 05:22 PM

nah this just 1 story no basement and the floor is 6inches thick so its good and strong to hold it...

manhattan42 06-04-2006 08:56 PM

A 6" slab is inadequate as a footer in most locations for a block structure of this sort, especially if you live in a high seismic zone and are subject to freezing.

What state? What County?

Chuckman 06-05-2006 04:45 PM

haha kentucky, usa; and 6inches is adequate enough to hold my truck so well its to late to change anything because i already started blocking it i got about 5 feet of block on it now so

Chuckman 06-06-2006 06:24 PM

ive got it all blocked now ive worked day and night now i just gotta wait 4 weeks for my garage door and entry door, lowes doesnt carry 9x10 heres so they had to order it.

So how many blocks did you use? Show us some pics.

Too Bad
It is a code violation to not install proper footings in Ketucky.

Kentucky uses the International Residential Code 2003 statewide.

Without proper footings installed below frost level, this building will remain unstable.
