Infill ?

[st247]

Just had a structural engineers report done for a property that my mother in law is buying. Haven't seen the report yet but have spoke to him about some cracking on interior walls. He says that it might be caused by the "infill". He suggested getting a test done to check.

So, two questions really

1, What does he mean by "infill"?

2, Anyone know what's involved with the test? and should my in-laws be concerned.

Thanks

Haven`t got a clue but then I`m not a Structural engineer and I`m not paid to type on this forum...I just do it for fun

Without seeing the report, maybe hes sugesting the cavity wall insulation.. but cant see how that would cause cracking unless you have alot of moisture in the property

Best thing would be to ask the surveyor what he thinks he meant.

I agree with Static, some of the foaming plastic cavity insulations, applied through holes after the house is built, can expand as they set, but I wouldn't expect them to crack the walls. Fireglass fluff doesn't expand, and I don't think the old polystyrene beads would either.
