A work colleague rendered a wall about ten years ago in someone's back garden.
Recently been called back to plaster some walls internally and he asked us for take a look at the rendering from years ago...
The wall is bout 1200mm high and about 6/7 meters long. There is soil about 2/3 feet of soil behind it.
The render has shelled off the height of the wall at about 1.5/2 meters increments. And the render is still solid, just not cohering to the wall...
I assumed this would be because moisture is getting into the soil and through the block work thus affecting cohesion between the block work and render?
We have thought about fixing EML to the wall but was wondering whether threre is some sort of waterproof barrier to which we could use or would the EML be enough in its own?
