Slab crack repair

According to the causes of cracks, slab cracks can be divided into the following two categories. 

1: the cracks produced by the force. It is mainly the uneven settlement of foundation, the strength of concrete and the serious shortage of concrete slab, and the occurrence of disasters and accidents. 

2: a crack that is not produced by force. It is mainly caused by factors such as temperature, shrinkage, expansion and construction.

About 90% of the floor cracks are caused by temperature and shrinkage. Such cracks can be repaired by automatic low pressure crack injection adhesive. Automatic low pressure grouting technology is a comprehensive technology including materials, machinery and construction. After grouting, the cracks inside are filled with epoxy resin. The tensile strength and adhesive strength are high and there will be no two cracks.

Because of the serious shortage of concrete strength and concrete plate thickness, the cracks produced by disasters and accidents, which have great influence on the structure, it is necessary to adopt scientific methods to repair and reinforce the concrete cracks.
