I've just measured the depth of the pattress's in my new house and they all appear to be 25mm deep and they sit flush against the concreted wall blocks.
Considering the idratek datasheets specify 35mm boxes is my only option going to be to chip away at the concrete blocks?
If this is my only option has anyone else done it and was it hard work? I can imagine brick being more difficult.
