In order to prevent the concrete floor in the course of the use of thermal expansion and contraction of unnecessary cracks and damage to the concrete pouring molding must be carried out after the scientific anti-cold shrinkage, so the treatment of the seam is very important. When the surface concrete strength reaches about 10MPa, the concrete ground is cut by the professional cutting machine according to the design specification size (6M * 6M) and the depth of the seam (1/4 to 1/3 of the concrete), and the polyurethane meets the design requirements Glue filled with joints, construction sealant to avoid the introduction of air.
