Expanding foam for fence posts.

[Russell griffiths]

So as the title says

i have seen a product on you tube for fixing fence posts, that is an expanded foam type stuff that got poured around a post

anybody seen it or know where to get it. 

 

I have a couple of loose gate gate posts that are moving due to the clay cracking around them and a series of 75mm wide cracks around them that would be perfect if I could pour something down them.

Not seen this one but if you can’t track it down I would use a liquid grout, i used one for a job in Aus for a very specific loose 1 ton stone slab. Rather than lift it we just poured grout in. Worked great.

 

 Conbextra do a range of really good ones the GP is genaral purpose and the UW is underwater both pourable to fill gaps 10-75mm.

 

fairly well priced if you can find a local supplier.

Didn't someone already post on here about this?

 

Just search "Sika Fence Post Mix". Sellers on Amazon, eBay etc. About £12 a pop. Not sure how many posts that'll do.....think one bag per post.

 

There seem to be makes other than Sika too, eg:

If it's just the clay soil shrinking in the dry weather, I would just be watering the ground around them for a while to make it swell up again.
