We offer stairwell drains that fit any size stairwell. These drains are designed to take on a high volume of rain water that your small inadequate floor drain cannot handle. Your newly installed stairwell drain quickly directs water into the Armored Basement Waterproofing System or directly to a new sump liner. If you do not have an Armored Basement Waterproofing System, we can tie this drain into your existing drainage system or we can even place a sump liner and pump directly in your stairwell to manage this water at its source. In this case, the sump liner acts as the drain.
