How much is the uneven wooden floor of home decoration qualified?

Whether the foundation ground is qualified when the wooden floor is decorated is mainly judged according to the following aspects:

? 1. The height difference within 2m of the foundation ground diameter is within 5mm;

? 2. The ground should not be uneven, even if there is a height difference, it needs to be flat and smooth, and there should be no sudden uplift or sudden sinking into the pit;

? 3. The foundation ground needs to be cleaned, and there can be no sundries.
