I would like to build a stone clad tower as part of my new house. The ICF system would give me all the strength, insulation and easy of construction I could wish for - but can it be adjusted to make an internal radius of 18' to 20'.
The tower would have a ground floor of poured concrete, a first floor as a libary and a vaulted 2nd floor as a master bedroom. All windows would be of the same size (aprox. 24'' x 80'')to allow for the radius.
Articles mention 'curved walls' but lack any specifics.
Any insight is much appreciated

| This can be done with relative ease. What specifics are you looking for? |

I Like it when some thinks it can be done with relative easy!
Are the individual blocks cut/reshaped and then fitted together. Do manufactures produce a more flexable block that has a little give in it? Is more bracing required? . Can a wall of this height be poured in one operation. How are the windows allowed for. What sort of stone cladding is used -man made or quarried - adhesive or mortar?
Thanks |

Actually this can be done with relative ease. I use a product called Granite block and it is a pretty hefty post and beam block that can be stood on end for such a project. It measures 16" x 48". The fastener is resessed 1/2 inch into the foam so you can profile the block without hitting the fastener. This is really great stuff for doing rounded and straight walls. I have done radius down to 4 feet with the product. It stacks fast and the last project I did I staked it 12 feet and poured it in one shot vibrating the concrete. You already said you have allowed for the window in the radius wall so I won't address that. As far as the second floor we imbedded bar joists at the 11 foot level for the second floor and on 2 foot centers with a concrete floor pourd over pan deck. The house was EFIS and sheetrock inside. You can buy sheetrock that bends for just such occasions.
I don't know what else to tell you. The biggest problem is putting in a straight window in a radius wall that has not allowed for it and having it look right. So the window size is critical. Oh yes this block is 9.5 inches wide. The company is walltechnologies.com need pictures I can email you some. |

| Just to answer some of the previous posts questions. The blocks are foamed together or cut with a skill saw to accomadate the radius of the wall. Set the saw at the proper cut, cut lengthwise down the block and away you go. I glued the block together although in large radius walls of 18 and 19 feet the tongue and groove will hold the block all around the parimeter. The reason I used glue is it significantly reduced the need for bracing. By the way no blowouts on the pour. |

Curved walls can be achieved using the majority of systems out there. However, you should be aware that this is a very time consuming process. Even after getting it to a science, it still took 10 to 15 minutes
to cut,bend and glue each block. I actually
spent 1 month of Sunday afternoons preparing
blocks for that "round room" project.
Amvic has come to the rescue of this application,and now offers prefabricated forms to accomadate 3 different sized radii.
If given advanced notice,they can customize
the template for you. It is available in all
the block sizes (4",6",8"). For more info
on this, feel free to contact Mr. Paul Camozzi at 1 877-470-9991 or visit the "on line support" at the Amvic web site.
Hope this helps. Take-care,sincerely.

The simplest system we have found for curved radius walls is the TF System. The vertical forming system makes for an easy install with minimal special cutting required. It goes up with the speed of straight wall forming. You can pour it in lifts of 12 ft., no vibrating is required with the proper concrete mix.
The greatest thing about TF is you can form your lower floor, build your 2nd level floor system to work off of, which attaches directly to the inside of the forming system, and continue stacking your form system for the next level the day after you pour the lower lift.
Simple and easy for what you're looking to accomplish. |

| Jim: Is the capability to build the floor system something that you think is a feature of TF? We have used several different systems in such a manner. We also build the basement walls, set the floor system (decked and all) stack the upper floor walls and then pour it all at one time...granted, this method isn't always the way to go, but we do stack the basement, set the floor and then pour the basement all the time. Just curious since your post insinuated that you were only able to accomplish such a task with TF. |

We also have installed main level floor decks before pouring the basements. Using several block style forms. This is probably more common than we may think. And possibily the biggest icf speed advantage over conventional built homes. "Wow no sub contractor delays". Why don't they get it?. I believe the main advantage with TF would be that the floor joist would rest on a solid steel structure. So no adjustment would be necessary. Although we have never needed adjustment when using a ledger.
My question Jim, is where do you cut the foam to make the radius? And do you shape it to fit the ladders?
