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 !!
