Wind Problems...

[WiltshireLink]

Hi All,

 

No it's not sprout related...

 

We have been progressing well with the Nudura but this wind is causing havoc.

 

We haven't got scaffold or alignment system yet as we weren't that high but getting blocks up to the near joist level and the wind is just blowing it over or off the DPC block.

 

Would the scaffold/alignment really combat the wind?

 

Any tips? I thought about bracing it vertically to the concrete filled DPC level to strengthen it

 

Cheers

I didn’t get the braces on site until I had the whole structure up to 2.7m we had some bad wind and only lost a block or two. 

Start at the corners and leave some gaps out in the middle to let the wind through. 

You will need loads of scaffolding boards for when the braces come, I don’t think many bracing systems hire out with boards, so you might as well get 20 boards now and a bundle of batten and get it propped, ready for the bracing system.

perfect  thats what I was thinking  cheers!

@ToughButterCup  Will give you the low down on this.

Our ICF build (Durisol) I did 6 blocks high and then concrete filled.

Brace as you go either with timber or alignment system.  Broken blocks might only reveal any damage when you come to pour.  Bridge between your rising walls and your ground floor.  Fix down as well as laterally. Close off your cavities rather than cutting holes in corners.

 

Building off a ladder holding a box kite is as fun as it sounds.

Did you brace vertically on the inside too?

What do you mean, temporarily or for pouring. 

If temporarily then do whatever you feel needs doing.

 

Same for the pour really, I over braced everything, but didn’t have a single issue apart from one reveal that I had actually forgotten to put screws in some timber.

Half a dozen screws later it was all fixed.

 

too much bracing???

probably.  

Did I have any problems??

no.

I'd say no.  The power of the wind is amazing, and it especially likes to damage  partly built structures.

No sorry, just whilst awaiting pour, I will  using alignment and scaffold for when pouring etc. Cheers

I built ICF (Poly Steel), in the Highlands, and wind needed thinking about from the start. We had to strap our block pallets to each other to stop them blowing away.

 

I used scaffolding on the inside, and timber bracing as I went.

The wind defences are going in! Been longing to do this all week.

 

Thanks all for your help

Just interested, and I have no advice to offer.

 

Is there any stipulation on constructing in vertical stages?

For a structural concrete wall it would only be done with a lot of attention , and steel, at the overlaps.

But if it was hollow concrete blocks I would certainly want to do it in stages, just for convenience.

And with this lightweight system there would be the advantage of the dead weight and strength. 

I guess it isn't allowed.

Typically you try and have the ICF bracing system on site prior to start and install as soon as needed, building ICF in vertical stages would typically make the project cost prohibitive just in concrete pump trucks plus the additional .5-1 m3 of concrete needed each time you place concrete. With the exception of tornado style winds, ICF when braced prior to concrete placement holds up quite well, perhaps a bit of adjustment needed after the winds prior to placing concrete
