Aseismic reinforcement of buildings

The building does not meet the requirements of seismic design, therefore it need for strengthening.There are some cracks in the wall, and the pressure injection should be treated first, so the engineer use HM-120L crack injection adhesive for crack repair.

Project overview

This works is the city of Beijing Xicheng District 2-15, the main structure is the 6 storey brick structure, built in 1949, has been used as a residential building, the construction area is 2866.2m2, height: one to six is 3 meters, the building height: 18.6 meters, in 2012 for safety and seismic identification, this project does not meet the requirements of seismic design, need for strengthening.


There are some cracks in the wall, and the pressure injection should be treated first.

Strengthening method

Crack repair


(1) grouting device is light in structure, convenient in construction, and no need for electricity. It can be used in harsh environments such as horizontal direction and vertical direction, high altitude, barrier, field and power supply. It has strong adaptability and no noise, convenient and safe.

(2) a population can be injected into a single crack at the same time. It is automatically injected. Because the inner hose and sleeve of the grouting machine are all transparent plastic, the injection is clear at a glance. The grouting effect can be completely confirmed at the scene, and the grouting quality is reliable. 

(3) the grouting construction speed is fast, the efficiency is high, and the time limit can be saved.

(4) the grouting resin and its supporting materials have good performance, easy to use, small toxicity, stimulant odor, on-site civilization, and safe to use.
