The backing cord may be used under 20% compression to form a backing under surface sealants. The cord forms the optimum sealant shape to minimise the strain and adhesion stresses on the sealant when subjected to movement. The closed cell construction also prevents moisture from being absorbed

Applications which the backing cord can be used in are:

  • Saw cut joints / Joint sealing
  • Joint filler for pre-fabricated houses, tunnels, subways, bridges and concrete structures
  • Seam coupler for water supply and sewerage pipes
  • Expansion joints for liquid reservoirs, swimming pools, dams and round moulding in the furniture industry
  • Back up material for window and sash frames
