The engineer micro-porous grouting technology is a new technology specially designed for the repair of stone floor hollow drums and stone bricks. Using high-pressure injection principle, the low-viscosity, high-strength, micro-expansion hollow drum special repair material engineer grouting resin is injected into Inside the stone floor hollow drum, the grouting repair of the hollow drum area is automatically completed, and the adhesion, integrity and durability of the concrete structure, the stone face brick and the base layer are improved. This technology is the best way to repair all kinds of empty drums. First, use 1. Double-cast concrete hollow drum: concrete laminated layer, cement mortar surface layer, wear-resistant floor, underground garage floor, factory floor cracking and hollow drum repair. 2, stone, tile empty drum: wall, floor paving stone, facing brick hollow, warping repair. Second, the cause and harm of the empty drum Empty stone floor, usually refers to the phenomenon of gap between the surface layer and the base layer due to poor bonding, commonly known as two layers of skin. There are two kinds of common empty drums. One is the concrete stone floor hollow drum. Usually the concrete ground structure is on the surface of the concrete structural layer. After the second pouring of 50~100mm fine stone concrete, it is directly used as the surface layer or leveling layer. The concrete that is poured once is easy to appear empty; the other type is the empty drum after the stone and the tile are laid, which affects the function of use. Third, the correct stone floor hollow drum repair method The original repair method is to remove the concrete and re-cast the concrete, which is not only time-consuming and labor-intensive, but also causes vibration damage to the concrete during the cutting and cutting process, and expands the empty drum area; the more common problem is that there is still space after the heavy-duty concrete The drum is possible. Fourth, the engineer empty drum repair special resin Engineer AB-5 hollow drum grouting resin, specially developed for concrete hollow drum repair, widely used in concrete, ceramic tile, stone and other empty drum repair, can be infused through low pressure and high pressure, after repair and treatment can completely cure the hollow drum problem. [Engineer AB-5 hollow drum grout resin characteristics] 1. Low viscosity, high fluidity: It can penetrate into the subtle empty drum position to achieve full filling effect; 2, no shrinkage, micro-expansion: the resin body does not shrink, after filling, it can ensure that the empty drum position is full; 3, high bonding strength, two-way penetration: the base layer and the surface layer are firmly bonded; 4. Green and environmental protection, this material is a green environmental protection product, which will not cause pollution and persecution on air quality and grassroots, and is suitable for indoor environment. 5, good durability: good resistance to deformation, durability and concrete synchronization. The empty floor of the stone floor often originates from a small crack that is insignificant. For the concrete structure with secondary casting, the hollowing of the stone floor between the two layers is often the most important cause of concrete cracking. Therefore, the problem of secondary casting and emptying is a problem that we should pay attention to and urgently need to solve.
