Is it possible to put a damp proof membrane under my paving stones to stop rain water seeping under my caravan

Answer 1

Wow haven't heard the word caravan in quite awhile.

You don't state what the "vehicle" is resting on. Soil? Blocks? Perhaps not a Slab?

Seepage, especially in a heavy rain might not only begin at ground level, but from beneath and leach up.

You could try creating a "berm"? You could try a skirting/flashing, buried a few inches into a perimeter, but too, part of your problem might include water that runs from the roof, straight down?

Certainly Your notion is worth a try,,,FIRST,,,and determine how effective it is. You might also try Grading the plot away from the vehicle, to promote some natural drainage.

I offer one more, albeit a bit tacky. You could put rain gutter at the perimeter, at the point where water might flow directly down the walls of the "caravan" and divert that away.

ADDED THOUGHT: You might also consider a French Drain; rimming the perimeter of the "caravan"

Answer 2

Purpose of damp proof membrane is to stop rising damp, not rain as you suggest. Sounds like you need a skirt or bund to stop rainwater running under - if the space below caravan is ventilated it should stay dry(ish) under there, and any water that does get under should ideally be able to drain away, rather than be trapped by membrane.

Answer 3

Hi I have lived in a caravan for years and don't recommend it lay your paving stones with a good 3 inch of sharp sand under them that will do the trick

Answer 4

Don't put membrane under a caravan/ mobile home / trailer , it will only collect moisture. Good drainage away fron the structure is best, even if it means digging a french drain.
Provide good ventilation under the structure, to prevent rot.
If it's too cold inside provide floor insulation.

Answer 5

i dont understand this question but why dont you have some flags runnin away from you caravan , because if you anything airtight and waterproof under your flags they will sink in all diffirent ways

Answer 6

listen to the xenon fellow. you should keep as much natural drainage area as possible

Answer 7

NO ..NO .AND AGAIN NO where do these question come from?
