The flexible plug expansion joint system, TENSA-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 TENSA-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 TENSA-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.
TENSA-POLYFLEX-ADVANCED PU joint for road bridges with high loads and large movements with continuously applied asphalt surface
TENSA-POLYFLEX-ADVANCED PU joint design with reduced width and small perforated steel angles is used for light loads (e. g. railway bridges, park decks, airport or railway station joints, commercial buildings, industrial plants)
