Wanbang gypsum-based self-leveling has many advantages:  

① Used as a "floor heating" screed covering layer, with good thermal insulation performance (compared with other heating methods, the floor heating can save energy by about 20%. If a zone temperature control device is used, the energy saving can reach up to 40%); it will not look like a cement mortar layer In that way, cracking, bulging and other phenomena occur due to thermal expansion and contraction; in addition, the floor after gypsum-based self-leveling mortar hardens has a certain elasticity, and the feet feel warm and comfortable; and it has a certain sound insulation effect. Gypsum-based self-leveling mortar is superior to traditional cement mortar in terms of strength stability and thermal stability, and is the preferred material for floor heating systems.

② Under the same conditions, the shrinkage rate of cement-based self-leveling mortar is much higher than that of light-weight self-leveling mortar. The heat-resistance of light-weight self-leveling mortar is basically stable at 50 ° C. The shrinkage values at 28d and 194d and the resistance to bending and resistance The compressive strength remains almost the same, without bulging and cracking.

③ The porosity of lightweight materials can play the role of sound insulation. The lightweight self-levelling mortar has a low density, which can reduce the bearing capacity of the building. It does not contain formaldehyde, casein, VOC and other harmful substances, and has no ammonia gas release. It has significantly improved the environmental protection standards of the entire decoration and is a green and energy-saving type. product. Gypsum-based self-leveling mortar as a ground screed has the advantages of other materials. It is an important product that replaces cement and reduces carbon emissions. It has the social and economic benefits of energy saving and emission reduction.

④ The multi-functional lightweight self-leveling construction is fast and can be pumped. The self-leveling ground can easily meet the requirements of wooden floor installation.

⑤ Using self-leveling ground, the thickness of the cushion layer of the heating radiation floor can be reduced, and the weight density of the lightweight self-leveling mortar is low, which can reduce the self-weight of the structure, thereby reducing the main construction and installation costs.


The problem of floor cracks in buildings has always been a common problem with building quality, which is difficult to cure, especially in northern areas where floor heating is the main heating method. Ground cracking makes developers miserable. Ground cracking is extremely common and difficult to cure. It is easy to cause owners to complain. To solve this problem, developers add finer crack-resistant steel wire mesh, glass fiber mesh cloth, and even 6 ~ 7cm fine stone concrete. During construction, these methods reduce the generation of fine cracks to a certain extent, but the possibility of cure is not high. In addition, the traditional fine stone concrete floor is difficult to ensure the consistency of the elevations of the four corners in the construction process. When the floor is uneven, the owner needs to re-level and level the floor, which costs labor and money.

In the background of full renovation, wooden floor + self-leveling is standard; in addition, the "Evaluation Standard for Prefabricated Buildings" after February 1, 2018 will also list full renovation as a mandatory option. In the future, there will be a large number of hardcover houses entering the market. The decoration of wooden floors is already a standard practice delivered by developers. The requirements of wooden floors on the flatness of the floor are extremely strict. At present, the cement mortar cushion can not be used to meet the flatness requirements of wooden floors. This is the current standard practice for screeding wooden floors.
