Delta Amphibia – Pre- Post Applied Waterproofing Membranes

Perfec_Bind_Amphibia_InstallKey factors assessed included:

  • Resistance to water and water vapour — the system provides an effective barrier to the passage of water under hydrostatic pressure and water vapour from the ground.
  • Resistance to mechanical damage — the system will accept the limited foot traffic and loads associated with installation.
  • Durability — under normal service conditions and when suitably protected, the system will provide an effective barrier to the transmission of liquid water and water vapour for the design service life of the structure in which it is incorporated.
