Q.1) How does HydroHALT perform under joint expansion?
Joint expansion between a shower tray or bath ledge and adjacent wall creates tension in the sealant bridge connecting the shower tray or bath side wall to the HydroHALT strip. Joint expansion can occur along both the horizontal and vertical axis.
Vertical joint expansion between the ledge and shower wall is substantially ‘tension free’ because only the fleeced portion of HydroHALT is bonded to the shower wall and the lowermost boundary of this fleece portion lies 14mm above the sealant bridge bonding HydroHALT to the shower tray side wall.
Downward movement of the ledge due to an imposed load or joist shrinkage causes both tension in the sealant bridge and tension in that part of the HydroHALT strip not bonded top the shower wall. The HydroHALT sealing system accommodates this joint expansion through both deflection in the HydroHALT strip at its point of contact with the sealant bridge and shear elongation of the sealant bridge.

How a HydroHALT/Sealux-N joint 5mm wide x 7mm deep accommodates movement.
Good adhesion between Sealux-N and siliconized face of HydroHALT is critical if the sealant bridge stretches under tension. As the PDF and video below highlight, the bond formed between Sealux-N and the siliconized face of HydroHALT is tenacious stronger than the sealant itself!
