After the Beginning of SummerCrashbandicootrunOfficially enter the rainy seasonCrashbandicootrunThe rainfall and rain increase obviously every day, which is the peak period of frequent leakage in the basement. As a common stubborn disease and common problem in construction engineering, basement leakage not only seriously affects the function of the building, but also has some hidden dangers, which may directly threaten the durability of the building and the life and property safety of users. However, in real life, basement leakage is often difficult to cure because of its complex causes, high technical risks and concealment.
Aiming at the pain point of basement leakage, Dongfang Yuhong launched a new upgrade of YH-101 oily polyurethane grouting and YH-201 waterborne polyurethane grouting in 2023. The two products meet industry standards, meet physical performance and environmental protection indicators, and can respond to different needs and rapid maintenance of all kinds of common water leakage. In practical application, the curing speed of the product is fast, and the water can be stopped quickly, and the single group can be used in separate buckets, which is efficient and convenient.
A few days ago, a completed residential district, due to the leakage of the underground garage, led to the delayed opening of the underground garage, which not only caused serious trouble to the owners, but also buried hidden dangers to the building. In order to solve this problem, the professional engineer of Dongfang Yuhong went to the site and found that the underground garage in the district belongs to semi-underground structure, there are structural cracks, which is greatly affected by temperature, and the seasonal variation of groundwater level is obvious. Therefore, the simple use of a grouting material is not only unable to solve, but also very easy to cause re-leakage.
To sum up, Dongfang Yuhong provides the mixed grouting solution of YH-101 oily polyurethane grout and YH-201 waterborne polyurethane grout for the maintenance project, which provides a solid guarantee for the long-term safety of the project.
YH-101 oily polyurethane grouting solution has the advantages of short solidification time, uniform pores and high closure rate, and has a good sealing effect on the leakage parts with large amount of water. When the slurry foams with water, it expands quickly and the expansion multiple is high. when it foams freely, it can reach more than 15 times / 20 times / 25 times.
YH-201 waterborne polyurethane grouting solution has the advantages of short gel time and high expansion rate in the presence of water. The consolidation body can better seal the structural voids in the water environment, and has a good plugging effect for the leakage parts with large amount of water.
Combined with the characteristics of the project and the performance advantages of the two products, Dongfang Yuhong combines YH-101 oily polyurethane grouting with YH-201 waterborne polyurethane grouting in this project, and adopts the construction method of mixed grouting, which can not only meet the elasticity required for structural crack stress deformation, but also adapt to the complex environment of groundwater level changes, while stopping water and plugging, the water sealing effect of the maintenance and plugging project is more lasting and safe.
