Problems solved by technology

The above-mentioned non-curing rubber asphalt waterproof coating has the following disadvantages: heating is required for construction, not only energy waste exists, the construction period is long due to low construction efficiency, and the VOC emission in the construction environment will cause harm to the health of construction workers due to the large energy consumption of heating construction; wet interface The adhesion effect is not ideal, and it cannot be directly pasted
It requires high-temperature construction, which leads to the loss of the effective flow of the root-blocking agent during the heating process, and the process is not environmentally friendly, and cannot achieve a satisfactory root-blocking effect
