(1) The SPC lock floor belongs to the recycled material and material problems, resulting in unstable performance. After thermal expansion and cold contraction, the floor will warp, deform, peel off, etc.;
(2) If the floor is not deformed, but the floor and the floor are propped up, and there is an empty drum. Then it is caused by insufficient expansion joints on the wall.
