What is the best method to construct radius walls?  What ICF manufacture is the easiest to build radius walls?

Thanks

OK, I'll go first, check out TF The "Vertical" ICF system.

Fox Block makes a radius block

Integraspec has a radius mitering formula available. Whith their 8'' module in the panels it makes it easy and no waste either. You'll either have to build an outer wall which will be reused in framing or strap the whole radius with plumber strap.

NUDURA makes a factory cut, custom order radius form that is available down to a 3' radius.

jrsimmons,

Amvic also custom manufactures a radius block that they can build at the plant to meet your radius requirements (well unless the radius is incredibly tight). I would use A LOT of OSB around the radius as well as proper bracing to reduce any likihood of a blowout.

Sipper, can you provide something more substantive than "check out TF the "Vertical" ICF System?" This seems to be a theme in your posts. I am not knocking the TF brand, but your response doesn't seem incredibly helpful to the question asked.

Although I have not used them, the fact that only Fox Block molds a radius block makes that an obvious choice, they are 5', 6', 7', 8', 9', and 10' Radius. If that is what you need. Too bad they are only 16" long. Use plumbing strap horizontally to hold the radius together and a radius is almost easier than a straight wall.

If you have a miter saw no point in paying for specialty blocks.

My own experience, after working with many different ICFs since 1992, is the NUDURA form. Radiuses are easy to do on site, or can be ordered from the manufacturer. This is just one of the neat aspects to this form. Barb4

Have to agree with you Colorodo.  NUDURA is a clear leader with radius.   Eight foot outer section curves exactly and inner pieces lock together all the way up to any radius desired.   Little to zero external bracing needed for typical radius.  A NUDURA installer recently did a City Hall on the Texas coast with about 20 different radius (serpentine).  Regards.

ON City Hall -- more bracing than typical here because 90% of corners were not 45 or 90.  BTW,  City Hall pic is half way up.  I will add some pics with walls to final height of 18' later.  REgards.

Quad-Lock has an extensive history when it comes to radius walls. Installation is fast and simple and requires no special components to be ordered.

 

Radius walls with a radius as small as 2½' [75cm] can be built by making saw cuts on the compressive side of the panels. A sliding compound miter saw with cut depth control is most effective. A Flex Track or Regular Track cut to form the curve is used at the bottom of the first course of panels. Low-expansion sprayfoam (e.g. Enerfoam) should be used in each horizontal panel seam to make the radius rigid and to reduce bracing requirements. Again offset the panels from one course to the next by 24" [60cm]. Brace the radius more frequently than straight walls. J

One of my contractors in CA cut his Build Block and used my steel radius jambs and flexable top cap to make his project a success.  If I can help let me know.  I don't care what block you use.  I will need to get his permission to post his photos on here.  It is a quite impressive project.

We have installed 8 different block brands. All of the major brands do well with radiuses, as you can see from the photos. The spacing of the strongbacks will depend upon how tight the radius is, but figure on at least doubling the amount of bracing. I have found that fiber tape works well on the outside of the radius. I would have to agree that in one sense, a radiused wall is easier; in that it stays true while pouring; but figure on doubleing your labor rate for that portion of the wall.

I heard the Hobbs vertical ICF was really easy to install and comes to you with the foam already cut to fit your radius with less support bracing and labor.

I am no expert but the radius walls that the guys showed of the pool from Nudura insulated concrete forms look very impressive.
