I had sump pumps installed in my basement. The sump pump folks
jackhammered up a perimeter around the family room of about 2.5 feet.
They put concrete on it and tried to level it wth the rest of the
concrete floor, which is under 1960s vinyl tile, and so there was a
1/8" drop between the old vinyl tile and the new concrete perimeter. I
would like to lay new flooring over the tile -- haven't decided yet on
laminate or carpet. I thought you might be able to feel the drop
under carpet, and it might mess up the click-loc system on laminate.
So after some thinking, I decided to fill in that perimeter with cheap
self-adhesive vinyl tile first.
It almost works. The thickness is just right -- its 1/8" inch, and
where it works there is no longer any drop or unvenness in the
transition from the original vinyl tile. But the sump pump folks did
not lay the new concrete perfectly evenly. A few of these new vinyl
tiles "crunch" when you walk on them, as they are seesawing between
high spots and low spots. My guess is that if I go ahead with the
carpet or the laminate on top I would have crunchy parts of the floor.
("Crunchy parts" is a technical term.)
What can I put under the self-adhesive vinyl tile that would fill in
some of this gap and make it lay -- if not perfectly flat, then flat
enough? Preferably something with some give, perhaps something latex
