Hi all,
Wondering if anyone could help me with the following problem:
In certain areas on our walls, there is (what seems to be) a concrete internal render on the walls which is crumbling. These patches seem to occur on a random basis (on any outside wall; front, back, and side of the house).
I didn't think it was damp because some "crumbling" spots can be upto 15 centimetres high with no signs of the wall crumbling underneath them.
Does anyone have any ideas on what this could've been caused by? Don't want to call in a damp proofing company just yet, heard all the bad stories about them suggesting work that doesn't actually need doing...
I've attached two photos below (sorry about quality - off a camera phone)
Thanks very much,
Shockfire.
