Hi

We just bought a house.
We are a bit concerned about the condition of one wall.
Seams like it is made of some kind of sand?
And really easy to "crumble".
Maybe it is normal,just want your advice guys.
And which type of product should I take to refill the holes?
See photos.

Thanks for your answers.

its made from lime and sand, its quite normal, you can fill the holes in, use a pva solution on the area first to seal the substrate
