Hot-melt gasket


Hot-melt gasket

The specialized hot-melt gasket for tunnel waterproofing sheets is a high-performance, thermoplastic component made from a specially formulated mold using high-temperature injection molding of a polymer material (low-density polyethylene), resulting in a precisely sized, circular hot-melt gasket designed specifically for tunnel waterproofing applications (hereafter referred to as the "hot-melt gasket"). This product is primarily used for securing and installing waterproofing membranes, geomembranes, and other waterproofing materials in projects involving water conservancy, highways, railways, and tunnels. Notably, this innovative solution addresses a key drawback of traditional strip-based installation methods—namely, the risk of damaging the waterproofing sheet—while offering significant advantages such as ease of construction, excellent adaptability to irregular excavation surfaces, minimal risk of sheet damage, and lightweight design. As a result, it has gained widespread popularity among engineering professionals.
