Hello

we have a bridge up to a barn that has started losing its plaster. Underneath, there are some areas that are a bit loose and others more solid. Mixed with stones. Is the best thing to do: 1. knock off all the loose parts 2. prime 3. attach reinforcement 4. concrete. Would it be even better if between point 2 and 3 a thin reinforcement mesh is also placed? Maybe also insert some long ground anchors through the concrete into the soil? An acquaintance said to tear everything down and make a completely new one, but I want to keep the old look and I don't know how the slope would react. It’s not powder underneath overall, but concrete mixed with some larger stones. Thanks for all the input that can be provided.

What a nice rännebro ! (Even if it's apparently called 'brygga' in your dialect.)
Your acquaintance who thinks you should tear it down? Tell them from me that they are a cultureless barbarian who's actually a bit pitiable, because they haven't understood how practical it is to be able to drive up onto the ränne / loft.

I'm not a plaster expert, but I think any plaster is good plaster in this situation. You want to protect the concrete/stone construction from moisture and thus frost damage in the winter.

What a nice ramp bridge ! (Even though it's apparently called a 'dock' in your dialect.) Your acquaintance who thinks you should tear it down? Tell them from me that they are a cultureless barbarian whom one should really feel a bit sorry for since they haven't understood how practical it is to be able to drive up to the loft.

Yes, I want to keep it as it is fundamentally. Do you think my reinforcement ideas might be okay? Maybe a bit excessive, but I think it's better that way.

Yes, I want to keep it as it is basically. Do you think my reinforcement ideas might be okay? Maybe a bit excessive, but I think it's better that way.

Rännebro was new to me, thank you.

It doesn't seem to be a new crack in the picture, at least. I would knock and brush off all loose material. If needed, go over with a pressure washer. Mix some A or B mortar depending on how hard you think the existing surface is.

To make the mortar adhere a little better, you can mix a primer of cement and water to brush on before plastering.

If you want the new plaster to look older, you can dirty it with soil before it sets completely, mix water and soil and smear it on directly. Wash off after a few days so the plaster looks old.

Thanks a lot for the input. Everything is appreciated. Definitely going to use primer. The idea with soil sounds good. From what I see so far, it seems to be the plaster itself that came off due to an old crack at the top that can be seen. I'll seal it with mortar.

Big thanks for the input. Everything is a joy. Primer it will definitely be. The thing with the ground sounded good. What I see so far is that it seems to be the plaster itself that has come loose due to an old crack at the top that you can see. I will fill it with mortar.

the crack looks old and you can probably easily fill it with mortar. Fun project you have in front of you!

It will probably be fine there, g
