Basement Waterproofing - Clogged Interior Footing Drains

While removing the perimeter of the basement floor to install a drainage system, the crew uncovered an existing drain tile system along the footing. The problem with interior footing drains is not so much the shape as it is the location. A pipe with holes meant to accept water that is then placed below the floor and in the soil is begging to be clogged. When water cannot drain to a sump pump, the basement floor gets wet...or worse.
