Product Performance Overview

The test information offered below is formatted to provide a visual insight into how The HydroHALT Sealing System performs after installation when exposed to the mechanical stresses created by joint expansion between a shower tray or bath ledge and adjacent shower wall.

 

The need for joint seal flexibility

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.

Sideways movement of the ledge or shower wall that results in a widening of the wall/ledge joint is substantially ‘tension free’ in respect of the sealant bridge spanning the joint because the HydroHALT strip is not bonded to the wall adjacent to where the sealant bridge is bonded to the strip. Consequently, the strip is free to release off the wall if the wall/ledge joint expands laterally.

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.

The videos below speak louder than words!

How HydroHALT accommodates 6mm joint expansion between a shower tray or bath ledge and tiled wall.

1) HydroHALT joint expansion Test

HydroHALT accommodates joint expansion through elongation and deflection in the strip at its point of contact with the sealant, and shear elongation of the sealant bridge between the strip and shower tray side wall. When the sealant joint between the tile and ledge fails, HydroHALT contains the leak inside the shower area.

The adhesive bond between the HydroHALT strip and Sealux-N neutral curing adhesive silicone is tenacious.

2) Sealux-N/HydroHALT Tensile Adhesion Test

Good adhesion between Sealux-N and the siliconized face of HydroHALT is critical if the sealant bridge stretches under tension. As the video highlights, the bond formed between Sealux-N and the siliconized face of HydroHALT is so tenacious it is stronger than the sealant itself.
