Method for waterproofing expansion joint subject to hydrostatic pressure

1. Preparation treatment. Removing any loose materials ensuring a clean and sound surface.
2. Optional: – Where water is seeping through the slab. Open the cracks. Apply one coat of MAXSEAL FOUNDATION into the crack. And 50 – 100 mm on each side and leave overnite (this based on the experience that Maxseal Foundation tends to seal the seeping in some areas). This makes this area cost effective to seal.  As Maxrest replaces Maxplug. When there is no running water.
   Tech Tip. (a) Maxrest is cheaper than the Plug.  (b) Maxplug is harder to apply. i.e. takes more time
3.  Remove existing expansion joint sealing material to accommodate MAXPLUG. Apply the Maxplug against positive pressure inside joint. Continue placing the Plug until water is halted. (as per technical data bulletin) Diagram shows reverse / uncut best for locking in MAXPLUG .
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.
