Flexible jointing

Posted on Friday, February 27, 2009 in DIY Waterproofing, General Advice

Have investigated your site. The flexible foam you picture. Is this a brand name product ?

I am in WA & the places I have asked this week have never heard of it.

I am about to start 1 of 2 reno’s I have to do & like the idea of the foam vs silicone.

If it is not a brand name product which product is it?

Polyethelyne, polyurethane, Neoprene ? and where do you get it. Any help really appreciated.

Hi Millsy
The 10mm flexible foam is called spaghetti foam, plastic rope or Backer Rod.(now I’m confused) Some may know it by a different name. It is a closed cell polyethylene foam.
You should be able to buy it from Bunnings and most fibreglass outlets that sell waterproofing membranes. It is available in a varying thickness from about 6mm up to 40mm in 2mm or so variations. I have also seen it at 75mm thick!
I usually buy mine as I need it because it is vulnerable to damage. However, you can purchase it in rolls up to 50m.

I hope this helps you

Here are a few links to Backer Rod suppliers and info.

As you can see it is used fairly widely in the construction industry. But, try to buy it from a casual storeperson at Bunnings and you’ll be met with a very dumb look.

Cheers
