I'm using gravel to provide an incline for water run off away from the
house ?Managed to snag a load of gravel for nothing, so might as
well use it. ?Plus this is under the eaves of a house and the gutters
occasionally leak and overflow, ?so gravel is being used to
prevent erosion.
? I have one layer of gravel inclined away from the house and would
like to place a waterproof membrane over this layer, ?and then place
another layer of gravel ?on top. ? The first layer is already inclined
away from the house.
What type of membrane or plastic sheeting would be best to
use? ? ?Something that is fairly durable and long lasting.
Thanks in advance !!

fairly durable and long lasting.
And made to withstand water, temp extremes, sunlight and rocks on top?
? ?Pond construction liner.
EDPM (vs PVC) liner would probably be the Cr?me de la Crop.
You didn't say cheap.
Maybe try roofing supplier as well. I believe I've seen in this group
that EDPM is used in certain roofing applications. I know the pond liners
run 20 and 45 mil thick.
I agree that would certainly be the ultimate choice.

Some lower cost options include ?4-6 mil plastic or ?a single row of
roofing
shingles placed end to end.

I would use landscape fabric cut into strips. ?It is not water proof but
would serve the purpose of allowing heavy flow to run off.- Hide quoted

install a perforated pipe running to daylight ...........

far better to upgrade to larger gutters and downspouts. water
cascading down side of home can cause big grief like rot, mold on
inside of home, detoriation of brick and even siding.

better to fix the real problem than try to redirect water.
Hmmm,
Some learns things the HARD way. Doing things first time right saves a
lot in the long run. I think the real problem is undersized gutter system.

I'm not keen on the OP's plan either, but I'm not sure that I agree with
the gutter system being undersized. The definition of "torrential"
varies with location, but I recall a storm where we got 2 inches of rain
in 20 minutes. I'm not sure the gutter system exists that could handle
that.
