Hi,
I've some external retaining walls that have been built, but it is now no longer possible to get behind them. The majority of them have several drainage ducts. I've been told that it's not possible to render the walls as the moisture would cause this to blow. Is this true even of lime renders, as I thought they had some porosity?
If I can't render, what would be a good type of paint to use, assuming that it will hold?
Thanks,
