A dry well fed by a 4-in. PVC pipe running from downspouts can disperse the water gathered from the roof. It should sit on a gravel bed and be wrapped with landscape fabric that holds out silt. If water is still gushing into your basement, call in a professional. Otherwise, consider an interior gutter.
Special epoxy holds the gutters to the floor.
Interior gutter systems catch basement water and channel it to floor drains or a sump pump. If your wet-basement symptoms act like runoff but occur all the time, you're probably dealing with high groundwater. Unless the foundation is surrounded by soil that has a high clay content, which can hold rainwater and snowmelt for months, runoff problems usually come and go as storm water drains away. But if your basement is consistently wet long after a storm, or if water is flowing through your walls or bubbling up where the walls meet the floor, you probably have a subsurface water problem. Check with your city or town to see if the water table is unusually high in your area or if underground springs are common.
