Massive prefabricated house with expanded clay walls - experiences

Dear forum members,

I am considering the purchase of a solid prefabricated house from the 1960s. The walls are made of Leca expanded clay aggregate. Although the house is solidly built, a comprehensive modernization is due. Electrical, plumbing, etc.

The house is partially basemented. There are some moisture spots in the basement. In addition, the bricks in the base area, where the house is not basemented, are bursting. It looks like frost damage.

Does anyone have experience with such houses? For the renewal of the electrical system, work on the walls is necessary (installing new boxes, chasing cable ducts). Does anyone have experience with Leca expanded clay aggregate in this regard?

How do you assess the issue of moisture in the basement and the damage to the brick base?

Thank you very much in advance for your answers.

Best regards,

Andi

I would expect unproblematic work similar to pumice, but here there is a different view from .

Thanks already for the response. Does anyone have any ideas regarding the cracking bricks at the base and what this might possibly entail?
