Title: New DPC with cavity wall insulation
Post by RHyland on Mar 25^th, 2014, 8:19pm

Hi - can I have a new DPC injected if I have cavity wall insulation? What happens if the insulation is really wet? I have had conflicting advice.

1) Is the insulation Loose fill (installed after the wall was constructed) or installed to the rear skin when built ??

2) and are they going to inject the inner or outer skin... or even both??

3) Why are you having the injected D.P.C..??

and if the insulation is wet then there is already a problem!!
