Non-standard construction
Render covers a house the report calls Wates PRC. Why can the render not stand in for a look at the concrete panels?
Render cannot stand in for a look at the concrete panels, because the render is what is hiding them. The report calls the house Wates PRC, and the panels sit under that coat. The survey can name the system and describe the render: cracks, hollows, patches. It cannot see the panel joints, the concrete face, or any repair to the panels while the coat remains. A home survey does not sample concrete by looking at a covering. The render is a finish. It is not the inspection the panels still need.

What is the fuller explanation?
Wates is a precast reinforced concrete panel system, so the panels are the structure the name is about. Render is applied later, sometimes to change the look and sometimes after repairs. Either way it interrupts the view. A sound-looking coat can cover a cracked panel, and a cracked coat can sit on a panel the survey still has not seen. No opening was made. No core is described. The sentence about render is a sentence about render. It does not become a panel inspection because the house was correctly named.
Ask the solicitor for any Wates repair papers or structural report, and do not accept the render as a substitute. If the panels have to be seen, a specialist must be instructed to do that, which may mean opening the coat under a proper brief. The survey has not told anyone to hack the render off, and it has not called the coat safe or unsafe. It has said the panels were covered.
What should you ask your surveyor?
- What of the Wates panels was actually visible, if any of them were?
- Which render defects did you record without claiming a view of the concrete?
- Was any opening or core made, or was the coat left intact?
What are the typical next steps?
- Treat the render as cover, not as a look at the panels.
- Ask the solicitor for any Wates repair or structural papers.
- Instruct a specialist if the concrete panels themselves must be seen.

Also asked about this
If the render is new, have the panels been repaired?
New render shows new render. It does not show a repaired Wates panel, and the survey had no view of the concrete under the coat. A fresh finish can follow a repair or simply a redecoration. The report has not chosen. The panels were not inspected through the render.
Can a thermal image see the panels the render hides?
Not as part of this survey, which did not do that, and a camera image would still not be a core of the concrete. The report called the house Wates PRC and described a covering. The panels underneath were not looked at. No image was substituted for that look, because none was made.
