However, the waterproof leakage rate remains high. More than 90% of the leakage parts in waterproof construction are at the lap joints. Especially when the SBS hot-melt type elastomer modified asphalt waterproof coiled material is constructed by hot melting, the fire roasting is not in place and the high temperature aging occurs, resulting in the lap joints not being bonded densely and firmly. With the rapid aging over time, the lap joints leak and water seeps through, ultimately causing the waterproof layer to fail and the building to leak. Content of the Utility Model
