Landscape fabric is usually woven to create a water-permeable barrier that allows the proper amount of water to pass through it while also keeping water evaporation from the soil to a minimum. The holes in the woven fabric are small enough to prevent water from gushing through it and soaking the soil.
Water is repelled by the fabric, not soaked by it. This is not what you want. When fabric is created in this fashion, it will stay in place and will not allow water to get through. This means that you cannot continue using this landscape fabric without any concerns because it may let water through.
