Polyethylene cord for floor joints

baucord Polyethylene cord for floor joints

BAUCORD® is a flexible and chemically resistant material made of polyethylene foam. It is an integral part of the BAUFLEX joint sealing system.

  • Ensures the proper formation of space within the joints in external and internal concrete floors before filling with BAUFLEX joint sealant.
  • Ensures proper distribution of forces within the expansion joints, in a perpendicular direction to the joint, ensuring its correct work.

For professional use only.


  • Appropriate shape of joint sealant generating distribution of forces in perpendicular direction to the joint
  • Flexible
  • Non‐absorbent
  • High chemical resistance
  • Waterproof and steam‐tight
  • Do not degrade

BAUCORD should be used at ambient and surface temperature +10°C ‐ 25°C, air moisture max. 80%. Existing joints must be dry and free of any moisture (humidity <4%). Working areas should be well ventilated and protected against access by unauthorized persons and to maintain a protection zone against an open flame, especially the welding work.


Choose the size of the cord so that when inserted into the joint was squeezed in 25% and does not move during application of BAUFLEX joint sealant. Place the cord using blunt, rounded tool or smooth roller to appropriate depth to achieve the proper fulfillment of joint sealant.
