Rendering Non Standard Construction

Looking for some help from someone who has first hand experience of rendering a house of non standard construction (pre-fab) please.

The house is of the "Cornish" type where you have concrete slabs slotted into concrete pillars - hence lots of joints and movement. Was planning to SBR slurry, dub out joints between slabs, embed alkaline resistant mesh into sand/cement scratch coat and apply sand/cement/lime finish coat? Is this the best way forward? Job is price sensitive so not looking to use acrylic renders.

Also, concerned about bridging any damp proof course by taking render right down to grade. There is no visible damp proof course - the bottom slabs seem to sit directly on a concrete ring beam? Do these houses have a dpc on the outer skin?

If anyone has any useful advice/experience on rendering this type of house then would be happy to hear from you.

Ta,

Jon.
 
All prefabs when done up always had a new skin of brickwork round them, obviously expensive but nowadays maybe an exterior insulated render system is OK, some one will be along shortly who knows the drill

sounds like a post war social house the ones up ere were dashed and now as we move into the future the general idea is to fit an external wall insualtion system to all existing stock. as lucius says there. so if it is standard non cavity pre-fab then that is your only real sensible solution in todays market
 
Thanks for all the posts. My first instinct was to do insulated render but the chap is dead against it - not entirely sure why - but at the end of the day its his choice/money! Think in the estimate I send him I will point out that my preference is for insulated render and it could save him money year on year. Ta. Jon.
