We are going to install luxury vinyl plank flooring in our basement. This product clicks together and floats, much like laminate.

The cement slab/subfloor is fairly level, with one exception: There is a 36"W walkout door, and the floor slopes down about 1/2" over the 6-8" before the door threshold.

Is this 1/2" descent enough to worry about when installing the floor?

If so, any suggestions?

Thanks,

Jim

We are going to install luxury vinyl plank flooring in our basement. This product clicks together and floats, much like laminate.

Two questions:

1. The cement slab/subfloor is fairly level, with one exception: There is a 36"W walkout door, and the floor slopes down about 1/2" over the 6-8" before the door threshold.

Is this 1/2" descent enough to worry about when installing the floor?

If so, any suggestions?

Here's a pic of the flooring extending to the threshold showing the slope:

2. In the pic you can also see a marble threshold. This abuts the actual door threshold (which you can't see in the pic). Wondering if I should remove the marble threshold and put in one more suited to laminate or vinyl, with a lip to hold the flooring down under it. Maybe something like this:

If I use this, can I just bend the vinyl flooring down the slope and secure it under the threshold's lip, or do I need to fill in the cement to make the entry area level before installing the threshold and flooring?

Thanks,

Jim
