Sealing basement drain tile to mitigate mold/odor

Post date: 2021-10-28 11:14:27

Small house in the Midwest, built in the 1950s, concrete slab and cement block walls. A few years ago, I had drain tile (where the floor meets the wall) and a sump pump installed. This apparatus does what it says on the tin, collecting water that rises up through the foundation. However, the system intentionally leaves a small gap between the floor and the walls, such that water which might trickle in down the walls is caught by the drain tile. I need to seal the system so it is airtight. Special snowflake details inside.

Unfortunately, while this opening will capture water that runs down the walls, it also leaves an opening to sub-basement air, and to standing water that sits in the drain tile system, collecting mold. My home has mold and odor issues, and I strongly suspect that part of the problem is this drain tile open to the air.

See this image for example:

I'm trying to brainstorm ways to completely and seal the system. My first thought is to use a right angle piece of vinyl trim which meets the floor and the wall, and apply caulk such that it forms an airtight seal. I'd like your ideas and suggestions.

Thanks!
