ᐅ Exterior wall is crumbling—should I be concerned?

Hello dear forum,

I am new here and have a question for you! We are currently building a house and the foundation slab is already in place.

Our land has a slight slope, so there is an earth wall on one side of the property. Of course, there will be a retaining wall built there later. But now I am worried because some soil is breaking away. Is this normal? The wall is about 1.4 meters (4.6 feet) high and 15 meters (49 feet) wide.

Is it possible to build such a wall yourself, or is it better to hire a professional? It is not a retaining wall.

Best regards,
Silent802

In our area, the building authority is very strict about any slopes with a height difference over 1m (3.3 feet) being constructed at a 1:1 ratio (45°) and covered with a membrane.
Well, he does feed them after all. Oh dear :-)

According to the civil engineer and landscaper, everything is fine for now and can be adjusted after the house is built. The civil engineer will come back in about 3 months, and I will ask him to make the corrections then.

We have decided to build the wall in 2019 after all.

I think the idea with the wooden posts and so on is a good one.

You see, I didn’t intend to provoke more with my comment, but here you immediately get lectured about being a smart aleck and so on. Just talk to the civil engineer or groundworker and have the slope “softened” or graded. That will probably be enough up to the point of building the wall. On one side of our house, the slope has been like that for 2 years without any issues (apart from a few crumbs, of course).

Then you have very stiff soil, @Axmann. I have cohesive but very clayey soil here, which formed a 1:1 slope on its own after just one winter, meaning it slipped over a large area.

Regarding the wall: large sandstone blocks with edge dimensions of about 1 x 0.75 meters (3.3 x 2.5 feet) laid here cost around 120 euros per square meter (about 11 dollars per square foot) of visible surface when using stones from the local area. This is the absolute minimum price, as the stones are large and practically have no transport distance.
