Wall drying and renovation – A field report
The following report shows how effectively and simply a wall that has been soaked and salted for decades can be dehumidified and restored:
When we moved into our house, we had a relic of the original house – the old, wet and salty former stable wall directly on the border to our neighbour. The wall is continuous on 1,5m earth touching without isolation to the neighbouring property, which is situated higher. The wall was in a catastrophic condition – damp, full of holes and salty, the bricks crumbling, partly already broken out. The weeds grew out of the joints and the wall was partly already inclined in the direction of our property.
What could we do? After all, the earth from the neighbouring property presses against the wall on a length of 15m up to 1.5m height. So, a safe and stable solution had to be found. But all the ideas we had were not so easy to implement. Each of them meant that the wall had to be torn down and then a new wall had to be built. Before the soil needed to be stabilized…
Dehumidifying plaster as a renovation solution
But then we came across the aerodurit® plaster distributed by RENODRY – the EP 2010 dehumidifying plaster. It can be applied directly to wet and salty walls, has no service life, dehumidifies the wall and even stabilises it! We could hardly believe it. But the long-term references of more than 35 years – and the plaster still like new – convinced us, as did the overall concept of aerodurit® – only ecological building materials – no chemical additives.
And now the time had come, we were getting serious about the wall. Cleaning, scraping out the joints as good as we could, because the joints were still clay joints – not everything could be scraped out, otherwise nothing would be left. And then apply the plaster – one material for everything – fill in holes and joints, pre-spray and then plaster.
The result is impressive. The wall stands, looks beautiful and is dry. Even in heavy rain no damp spots appear on the plaster. More is not possible.
