Defects devaluing house.
New Home Expert:
On a new home the mortar shouldn't rub away with hand force. In fact you should need a hammer and chisel/bolster to chop it out!
DPC above the normal 150mm above ground level are probably cavity trays that are above anything that crosses the cavity such as a lintel etc. ON a timber frame new home a cavity tray is also above the fire sock cavity closers, (if indeed they have been fitted!!)
The one of the sandstone ledge may actually just have been built in for protecting the ledge during construction and was then trimmed back before render!
Bri:
The DPC is attached to the inner wall, it then goes over the xtratherm board, drops down the length of a full block and then goes under the outer block. It is like this all around the house so if it were a cavity tray, it would be one long continuous tray.
Here is what it looks like. There is a 3 inch gap between the xtratherm cavity boards when they are supposed to fit tightly together.
Bri:
My house is not timber frame. Here is an example of mortar joints.
New Home Expert:
The DPC is a cavity tray.
These can be just over openings and lintels and airbricks etc. They should have the ends turned up and weep vents to let any water out.
A cavity tray can also be continuous around the perimeter of the house. It will need to be lapped as rolls lengths are 10-20metres maximum and at the corners
Bri:
if it`s intended as a cavity tray why would they need a continuous one all around the perimeter of the house at second floor level? This breached the expansion joints and causes a slip plain.
