Should I consider a French Drain installation and also consider a installation of underground downspout extensions.Rain gutter downspout exit points,that discharge water in close proximity to your house structure foundation can be problematic.The downspout water that exits can cause erosion,wash away of soil,and increase excessive expansion of the clay soil close to the foundation structure.The downspout water should exit at least several feet away from the house foundation structure.A method of discharging the downspout water,is to collect the water in a drainage pipe.Then,install the drainage pipe extension underground,at least several feet away.Finally,surface the drainage pipe water so it can exit the pipe.The underground drainage pipe extension will carry a lot of water from the downspout,so the minimum size for the drainage pipe is four inches to perform properly.Connection of a downspout to a underground drainage pipe is done thru an adapter downspout to drainage pipe connector.The surface exit of the underground drainage pipe extension is a four inch grate.The underground drainage pipe extension is a good way to discharge excess water away from the house foundation structure,and will minimize soil expansion issues of a downspout exit.Carrollton Texas French Drain Services.
