which is considered the best method of finishing a basement floor.

Delta FL - states ti seal around edges to prevent airflow

Dri core- states to leave gap at edges to allow airflow

To be honest, I do not like an product that forms a cavity which will allow mold growth. There are two different schools of thought in regards to those types of floors.

1. No gaps.

2. Gaps for air flow.

No gaps means no air flow which will help dry a damp area. However it is my experience that there is not enough air movement or air flow with these types of floors unless you make a system that will exchange air in those small cavities. I have pulled up all types of basement floors to address mold. NO FLOOR is the correct answer.

A cavity-less floor is the only safe answer. I like carpet tile.

currently I have an olifin carpet which works ok because it can be bleached but it still gets stinky after a while regardless if I keep the humidity down.

cosella dorken also recomended on the phone to seal where the product meets the wall w/ a low expanding foam. this would isolate the floor from the livingspace and matches up w/ the above Building Science article
