    Our waterproofing specialist Steve Custus talked to the homeowners and ensure them that we could take care of their problem . We at Jamison Basement Waterproofing seen this type of water seepage problem way to many times . Water leaking in from leaky belico doors or from leaking basement exit stair cases . The solution was simple we wanted to ensure them that no water would ever get pass our Grate -Trench so Foremen Khain Carter installed the Grate Trench across the entire door way . The Grate Trench will channel the water seepage below the slab into our Grate Sump which is one of the worlds leading Sump Pump systems in the industry. The Grate Sump will pump the water out of the home and far away from the foundation , all while keeping the Basement floor dry ! The homeowners came home and thanked us on how clean our installation crew has left their property and how neat the worked looked . Problem solved !!
