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 !!
