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.
The POLYFLEX-ADVANCED PU plug expansion joint system can be cast into nearly any joint shape (e.g. upstands, skewed angles, T and X joints, etc.). Plug expansion joints are specifically suitable for the use in bridges, infrastructural projects such as architectural and industrial structures like shopping malls, car-parks, airport buildings, runaways or railway stations. Applications in pharmaceutical industries and hospitals where sterile joints and crossings are of the utmost significance are also to be mentioned.
