Specialized concrete floor air drum crack treatment ground air drum latest treatment technology Tianjin Zhengxiang Technology Co., Ltd. Micro-hole high-pressure grouting technology is a new technology for concrete hollow drum, stone surface brick hollow drum repair, using high pressure injection principle, low viscosity High-strength, micro-expansion hollow drum special repairing material——Zhengxiang AB-1 grouting resin is injected into the hollow drum to automatically complete the grouting repair of the hollow drum area, improve the adhesion of concrete structure, stone brick and base layer, and overall Sex and durability. This technology is the best way to repair all kinds of empty drums.
The color of the product is generally red outside yellow inside, the product surface for the micro-prism structure Reflective Film, the bottom is aluminum. Reflective principle is often micro-prism reflective, with its distant vision, high brightness, high angle, high brightness and thus to meet the needs of the rear panel, the rear board after weathering test.Even in extreme weather can also be normal use.
For the garages where there are already existing ground drums, it is recommended to use the Zhengxiang AB-1 grouting resin of Tianjin Zhengxiang Technology Co., Ltd. for grouting and repairing. Fill the cement floor with a full drum position to ensure the integrity and durability of the building and meet the normal use requirements.
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 the empty drum area is enlarged; the more common problem is that the concrete is still generated after the heavy hitting of the concrete. The possibility of empty drums. 
Zhengxiang AB-1 Grouting Resin is a special glue for cement floor hollow drum treatment. It can be grouted for various conditions such as mortar, concrete, brick and stone, and can be filled by low pressure and high pressure. After that, you can completely cure the empty drum problem.
Zhengxiang AB-1 Grouting Resin Features:
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.
How to deal with cement floor hollow drums has become a common quality problem in construction projects. The production of concrete cracks often results from the untimely treatment of the ground hollow drums, which can cause complete damage to the concrete. Therefore, how to deal with the cement floor is an urgent problem we need to solve today.
Tianjin Zhengxiang Technology Co., Ltd. can analyze according to the specific situation of your site, and have a targeted construction guidance plan. The Tianjingjing area can provide free technical guidance and construction. For details, please contact: Cui Gong 18522759269/022-26864563.
