Any experience of Amera Buildings?

They're quite robust if you fill the backs with expanding foam and prime them with a decent primer.

That's exactly what I do. I've been using some of their trenches and ruins for about 4 years and they're still going strong.

Is this the stuff in aerosol cans you buy in DIY shops for filling holes in walls around pipes etc?

Yep, that's the fellas. Gives the terrain a nice bit of heft too. I do like a bit of heft.

I agree, expanding foam would be good. I would use wall filler or plaster...

But that might just pop out because of the plastic.

They are VERY good vac-formings. I found them very good, but sold them on. I am considering buying a few more bits and bobs though.
