I have a french drain with gravel wrapped around landscaping fabric across our front lawn. Unfortunately we have a lot of clay in our soil and the clay has gotten into the fabric and completely prevents any water from getting through so that it could enter the french drain, leaving us with puddles of water on the lawn. We have now removed the soil above the french drain and cleaned the fabric. What should we do now? Should we lay some gravel above the fabric before we pile some a looser soil on it? Any advice would be appreciated!
