We have a house built in 1976. The house has a brick facade and at the bottom against the ground, the foundation has started to crumble. In some places, there are deep holes right under the bottom row of bricks. At the outermost part of the foundation, there is plaster and inside there is aerated concrete. Both the plaster and pieces of the aerated concrete have come loose.
Looking at the drawings, it appears that the bricks sit on aerated concrete, and under the aerated concrete, there is a concrete ledge.
How do I repair the foundation, and is there a risk of the brick facade collapsing if the supporting aerated concrete completely deteriorates?
See images of the foundation and also the drawing.
Buy a trowel that is about 20mm wide, or no wider than the smallest gap between the ground and the brick. Sweep the ground clean and place stiffly whipped Cement mix A on the ground, pressing it under the brick with the trowel, a couple of times until you get through. But don't smear it on the brick, you can't remove that. Tape the brick otherwise. The vertical joint between some bricks acts as ventilation; do not fill it in. You should only fill the horizontal joint under the brick. It must be above freezing temperatures around the clock when you do this.
That moisture/frost damage may be due to ground water (rain and snow) running towards the foundation and/or that the ground level is far too high (close to the brick).
