For the existing concrete hollowing treatment, it is recommended to use the Chengdu Zhongke Weiye microporous grouting series products for grouting repair treatment. Fill the concrete hollowing treatment position to be full to ensure the integrity and durability of the building and meet the normal use requirements. Main material: Grouting resin. Grouting resin is a concrete hollowing treatment adhesive, which can be used for grouting treatment in various situations such as concrete hollowing treatment of mortar, concrete, and brick slabs and concrete crack repair.

????Hollowing repair grouting resin: Grouting resin is developed for the repair of concrete hollowing and cracks. It is applied to the repair of concrete, stone, and ceramic tile hollowing. It can be grouted in two ways: low pressure and high pressure to solve the hollowing problem after repair. Product features: Low viscosity and high fluidity: It can penetrate into the subtle hollowing parts to achieve the effect of full grouting; No shrinkage and slight expansion: The resin itself has no shrinkage, and after grouting, it can ensure that the hollowing position is filled; High bonding strength and two-way penetration: It can firmly bond the base layer and the surface layer; Green and environmentally friendly: This material is a green and environmentally friendly product, which will not pollute the air and the base layer and can be used indoors and outdoors; Good durability: The material has good anti-deformation ability, and its durability is synchronized with that of concrete.

????The causes and hazards of hollowing Concrete crack hollowing usually refers to the phenomenon of gaps between the surface layer and the base layer due to poor bonding, commonly known as two layers of skin. There are two common types of hollowing. One is the hollowing of the concrete floor. Usually, the concrete floor structure is on the surface of the concrete structure layer, and 50-100mm of fine aggregate concrete is poured for the second time and directly used as the surface layer or leveling layer. The concrete poured for the second time is prone to hollowing; the other is the hollowing that occurs after the stone and ceramic tile are paved, which affects the use function. The correct method for repairing concrete crack hollowing: Hollowing microporous grouting method. The original repair method is to chisel and re-pour concrete, which is not only time-consuming and labor-intensive, but also the vibration and damage to the concrete during the cutting and chiseling process will expand the hollowing area; a more common problem is that there is still a possibility of hollowing after re-pouring the concrete.
