firstly i dont if i have opened this in the right section but i hope i have :?
I recentley had some work done in mt garden and i need help. We used to have a steep slanted garden which came down to meet a small pation area. We had the slope taken back and had a wall built to. The soil from the slope was placed behid the wall to level the land. There where soak away tube put in behind the wall to help remove the excess water( they were already there any way). The patio was also increased at the same time.
The wall that built was then rendered however since then the render has broken away from the wall.
My question is this What materials should i be using and in what mixture to render the wall. Also is there anything i can use to bond the render to the wall so this does not happen again.
Any help is much appreciated
