I want to mount a bed frame to 2 aircrete walls with a pillar on the unsupported corner. I've heard that anchors can tear out parts of the wall if overtightened. My question is for a load greater than 200kg (440lb) what is the best method to use, I've heard one can use some sort of expanding Resin.

A rendering of my idea Thanks


  • I think you may have misunderstood. Typically you'd use an expanding anchor, such as a split sleeve. – isherwood Mar 28 '18 at 17:27
  • Do these not pull out parts of the wall if overtightened? – Benjamin Brown Mar 28 '18 at 17:35
  • They will, as they would with regular concrete. I have no experience with aerated concreted and have declined to answer your question. Please don't interpret my comment as one. I'm just stating that foam isn't appropriate. – isherwood Mar 28 '18 at 17:38
  • Sorry, I read it wrong. It was actually resin – Benjamin Brown Mar 28 '18 at 17:43
