ᐅ Basement walls made of brick or concrete?

Our basement will be constructed soon, and the contractor recommended using concrete partition walls. According to him, the brick partition walls I had planned might cause problems if the basement ever floods. We have soil with a high gravel content, and I can easily imagine that heavy rain could push water from outside—flooding is not impossible.

How do brick partition walls hold up? Don’t they dry out quickly if they get submerged? Should I really choose partition walls made of concrete?

So: The initial approach is incorrect!
If you already know in advance that water could penetrate the basement, you need to secure (i.e., waterproof) the exterior basement walls so that water cannot enter.
If the waterproofing of the exterior basement walls is planned and executed according to the expected water load conditions, the material of the interior walls does not matter.
Whether you choose concrete or brick walls: both would get wet in case of water ingress; concrete also needs to dry, just like brick walls (however, with masonry basement walls, a bitumen membrane can be placed in the second mortar joint to prevent water that has entered from rising).

We have the same question. Fortunately, we don’t have any concerns about water, except during occasional spring tides. We want to choose waterproof concrete. The architect said that would be the right solution.

Are there any other experiences?

Yes, we have used this concrete as well. Initially, I wanted brick walls, but I changed my mind based on advice. It turned out to be the best solution. So, I would recommend it.

Actually, it doesn't really matter what material is used. Whether bricks or concrete, both will get wet. I believe the key factor is the waterproofing. If mistakes are made here, water will penetrate everywhere.

I see it similarly. Both approaches can work if done well.
