Good Morning Friends,

When installing drywall in a basement one would normally hold the bottom of the drywall off the floor just in case a leak may occur and then the water could be directed to a sump hole with a quality sump pump in the collection hole in one corner of the basement.

 

What methods would you use that would help direct the water to the sump hole?

Years ago we would snap a line paralell to the walls, use an air chisel and create a groove running around the perimeter.  Clean it thoroughly with wire brush and vacuum.  Then would come the liquid nails and plastic type base trim.  Caulk the the channel and butt joint and 45's and create a channel to the sump pump.  It did work but I thought it was kinda primitive.  I always thought the water would "pool" and you'd still have a moisture or humidity issue.  I'm not sure what they do today but their has to be a better way.

Good Morning Jeff,

You have the right idea however one could insert a champfer around the edges of the freshly poured floor and create a smooth groove for the water to run in and when the cement hardened you woud simply remove the champfer.

Thanks for your support.
