I am having similar problem with the basement slope being exceptionally steep around the floor drain (similar to this: How do I level a basement floor but not the slab underneath?). The discussion there seems to lead to a specific solution:
- Extend the drain to the new level
- Pour self-leveling cement to raise the floor
- Create channels in the freshly poured cement for the water to drain
So the questions are:
- Is that a practical solution to this problem?
- If so, which method would be most effective in crating these water channels?
- Using a wide screwdriver (how do you maintain consistent slope without displacing surrounding concrete)?
- Laying down a pattern of 1/2" dowls/PVC pipes (how do you construct this pattern? what pattern would work best?)
- What about cutting them in with a circular saw after the concrete sets (seems messy, time consuming, producing narrow channels with no slope?)
Well, as they say, a picture is worth a thousand words. So, ideally, I would like to see this method in action or in its finished state.
PS: I am also considering laying down Delta FL over the entire area to act as a vapor barrier/subfloor; laminate on top...
