The flexible plug expansion joint system, POLYFLEX-Advanced PU, is a completely new development based on elastic polymers and herewith a new generation of flexible plug expansion joints. Compared to other expansion joint designs, flexible plug expansion joints offer several advantages including: unsurpassed driving comfort, nearly zero noise emission, 100% water tightness, highly flexible installation possibilities in sections (e.g. lane-by-lane), etc.
The POLYFLEX-Advanced PU joint uses a durable, fully elastic material with a very high tear resistance and at the same time causing very low reaction forces.
