Fix the base for the threshold

[Arne999]

I have made a threshold in oak with a thin board. However, the base is uneven and at different levels. I tried building up the base with masonite pieces and then glued the threshold on, but it didn't work well.... There was quite a bit of glue to fill in, and the result was that the threshold warped a bit due to all the moisture from the glue....

Is there another good method that can be applied and then pressed on the threshold? Some 2-component compound that cures quickly, for example?

Take a picture of how it looks currently so it will be much easier to provide tips on how to solve it.

Is it not moisture from the outside? (seems like the front door) that caused it to warp, it would take quite a lot of glue for that to be the cause.

You can dab PY foam sealant there. Once it has cured (wait at least 24 hours), cut it to the right level with a sharp knife.

I suggest concrete filler, there are several different good and fast-curing ones with good strength and excellent results. Humidity zero and surface smoothness perfect.

nah the moisture probably came from the glue, no moisture from outside maybe a bit cold though.. Will try the above suggestion

As a craftsman, I would have made sure to prop up the foundation, or alternatively, use filler. Then I would have drilled and countersunk a couple of nice screws.
