Flatness check to the ground floor, 2m on foot can be used flat on the check the ground, 3mm thick feeler gauge to check the gap between the foot and the ground. If the surface flatness standard of pavement cannot arrive requirement, which will cause the floor edge collapse, overturn, arching, noise and other issues.
2, Surface moisture check
Check the ground moisture, moisture testers available ground moisture. Common ground standard < 20%, laying of geothermal floor standard <10%.If the moisture on the ground is too high, flooring will easily absorb water, causing the floor arching, drums, noises and other issues, so if the ground moisture exceeds the standard values. There is a need for dehumidification.
3,Check whether ground firm enough
See if the ground is solid, can be ground with a hammer or other object, check the ground for holes, peeling.If the floor has holes, or flaking, the ground needs to be reprocessed.Otherwise, after laying the floor for some time, because the ground is not solid, it will appear noise.
