Respected construction codes of practice worldwide adopt the same proven principles in respect of the necessity:
- to provide movement joints in buildings to relieve built up stress. The joint between a shower tray or bath ledge and adjacent wall is a movement joint liable to expand or contract.
- to ensure joint substrate compatibility and adhesion with sealants being applied to seal such movement joints. Sealants must not react with, but tenaciously adhere to joint substrates.
- to ensure the correct selection and dimensional application of sealant with a backer material to flexibly seal such movement joints. Joint design is critical for sealant flexibility.
HydroHALT is basically a three component sealing system comprising of:
a) The HydroHALT strip
b) A Sealant Backer Material
c) Sealux-N Sealant Adhesive
Sealux-N conforms to EN 15651-1: F-EXT-INT-CC 25LM, EN 15651-2: G-CC 25LM, EN 15651-3: S XS2. In common language it is a neutral curing, low modulus, highly flexible, sanitary grade silicone adhesive.
The selection of Sealux-N sealant adhesive and its proper dimensional application in combination with a backer material is the key principle upon which the HydroHALT Sealing System is founded.
What makes the HydroHALT Sealing System revolutionary is that we have combined this proven principle with a strip that has been specifically adapted for tenacious adhesion with Sealux-N.
The HydroHALT strip membrane prepares the shower wall substrate for an indirect tenacious but part-releasable engagement with Sealux-N and the adjacent shower tray or bath side wall.
This joint detail provides the benefit of allowing a relaxed separation of a lower portion of the HydroHALT strip from the wall surface behind, which in combination with flexibility in the Sealux-N created through the installation of the backer material, accommodates substantial joint expansion.
The HydroHALT Sealing System follows proven principles endorsed by Construction Codes of Practice and National Standards Authorities worldwide.
