Examination of AS 3740 and AS 4654.2 Fillet/Bond Breaker Requirements:

AS 3740 Fillet/Bond Breaker Requirements:

  1. Definition: Bond breaker is a system that prevents the membrane from bonding to the substrate.
  2. Class II Membranes: These medium extensibility membranes require a minimum bond breaker/tape width of 35mm.
  3. Class III Membranes: These high extensibility membranes require a minimum bond breaker/tape width of 12mm.
  4. Bond Breaker Profile: Although not explicitly defined, the diagrams in the standard depict a concave finish for the bond breaker.

Two application options for class III membrane bond breaker:

  • Option 1 (Mitre Finish): Sealant bead should extend up the wall and along the floor for a minimum of 8.49mm each (total distance of 16.98mm).
  • Option 2 (Concave Finish): Sealant bead should extend up the wall and along the floor for a minimum of 7.64mm each (total distance of 15.28mm).

Note: A concave bond breaking sealant bead provides a larger bond breaking surface than a mitre one when applied at the same distances, resulting in a smaller but equally effective bond breaking bead.





AS 4654.2 Fillet Requirements:

  1. Fillet Usage: Fillets are necessary when a membrane changes from a horizontal to a vertical plane or from one vertical plane to another.
  2. Fillet Size: The standard requires a 40mm x 40mm fillet for sheet membranes and a 15mm x 15mm fillet for liquid membranes. The 15mm x 15mm requirement for liquid membranes means the hypotenuse side of the triangle (the fillet) is approximately 21.21mm.

Remember, always check the fillet/ bond breaker dimensions with the product manufacturer's Technical Data Sheet to ensure compatibility with the membrane system and alignment with the Australian standards.
