WDVS dowelling? 24cm hollow block stone

Hello. I want to insulate my two-family house with ETICS. Built in 68, ground floor, upper floor, exterior wall 24 cm hollow block. I am concerned about the anchoring. The anchor holes do not weaken the wall (house) in terms of structural stability, do they? Thank you for the answers!! Best regards.

My contact person would be the technical phone support of the anchor manufacturers. There are stones that crumble if you hit them with a hammer. Have a system recommended to you and read the installation instructions carefully. One hole, one anchor, and your house holds; you should avoid 20 holes wasted per anchor.
