How to Replace A Fifty Year Old Footing Drain

February 9, 2016

Digging deep around the house is hard, so repair it right the first time, right? #MakeItLast

Chuck with Apple Drains in Charlotte, NC explains foundation waterproofing retrofit solutions.

Old drain tile can become clogged with dirt after years of service. The drain tile in the video was installed in the early 1960s, so it has been in service for over 50 years. 

 

Here's the step by step on how to replace a clogged old footing drain:

  • Step 1 is digging down to the footing to expose the drain tile.
  • Step 2 seal with foundation wall with paint on waterproofing membrane.
  • Lay a gravel base for the drain pipe. Gravel should extend about four inches below the top of the footing so that the pipe can sit level with the footing.
  • Lay perforated pipe on top of the gravel with the holes pointing down so that ground water rising from below will be directed auto daylight through the pipe.
  • Cover the pipe with gravel extending a few inches above the pipe and the footing.
  • Install a fabric barrier over the gravel to filter out dirt that will clog the pipes.
  • Backfill the trough making sure to slope the grade away from the house.
