I've got a basement entry way that's got some serious pothole(s). The
problem is that the water runs down the outside steps and puddles on the
floor. This then freeze/thaws and creates the potholes. So I need to fill
the potholes and add some slope to the floor so that the water runs down the
drain properly. I gather some cement:sand at 1:4 with some PVA is the way to
go? I've also read that I should paint the floor with PVA before I start?
The deepest hole is a good half inch and I want to at least an inch to the
outside walls for a 1/4" slope to drain the water.
Problem #2 is that the door to the house opens into the entryway, so sloping
the floor along this wall will be a challenge. Of course it's the same wall
that the outside door/stairs is on. I was thinking I could leave a pie shape
to allow the door to open, but this might look like crap, present a tripping
hazard and allow any water to chip up the new cement.
I was also thinking I could put a gutter (ABS cut in half) under the outside
door (it's one step off the floor) and run a drain pipe around the outside
of the room to the floor drain. This would not catch all the water (walls
are damp), but I think it's 90% of the problem. I'd still have to patch the
floor, but sloping could wait for next time, if ever.
So any thought on:
1) The best slurry for patching sloping
2) How slope under/away from the outswing door.
3) My gutter idea.
