Method to seal expansion joint subject to hydrostatic pressure

  1. Prepare area to be treated by removing any loose materials ensuring a clean and sound surface.
  2. Optional: – Where water is seeping through the slap once cracks have been opened apply one coat of MAXSEAL FOUNDATION into the crack & 50 – 100 mm on each side and leave overnite (this based on the experience that the MAXSEAL FOUNDATION tends to seal the seeping in some areas)
  3.  Remove existing expansion joint sealing material to accommodate MAXPLUG and apply against positive pressure inside joint until water is halted as per technical data bulletin. Diagram shows reverse / uncut best for locking in MAXPLUG .maxplug-squarecut-reverse-cork
  4. Leave approximately 50% of joint width in depth to accommodate MAXJOINT ELASTIC
  5. Apply MAXJOINT ELASTIC into the remaining void to the surface, as per technical data bulletin #156.00.
