Monocouche problem

[RichFree]

A customer has called me explaining they had a problem with rendering done by another company and the company have said they wont come bavk and do it as its down to the landscaping company , basically it has all blown and got salt deposits coming through the retaining wall , they have said that it had some black paint on the back of the walls where the soil was but they didnt know what it was and also there was pea gravel at the back of the wall
Does anyone have any ideas on what can be done as i dont want to knock it off and the same thing happens

looks like too much pressure from behind the wall.

there needs to be some weep holes for moisture to release

Thanks for your reply
I did think it needed weep holes but the builder dissmised it and has told the customer they are not needed as it had a tanking slurry and pea gravel behind it

This modern style of garden feature wall is fraught with bad jobs. Loads appear on here.

I wouldn't get involved. More hassle than it's worth for what? £500 nah

These often fail and it is not down to the renderer. Everything about these walls are wrong in the way they are built.

Usually no tanking from behind, inadequate coping stones including a lack off a dpm under them and built in drips , no dpc and nearly always never a minimum of 150mm above ground level.

I Stopped doing these walls years ago, not worth the argument over blame
