Refurbishment Requirements

• Confirm the structural integrity of the existing deck:
  -Capacity of taking additional loads during installation.
  -Pull-out resistance
  -Degradable supports should always be examined for their quality
  -Repair and replace as required 
• Insulation boards need to be replaced if they are wet or degraded
• The condition of the existing roofing membrane will determine the necessity for a separation layer. Follow the instructions mentioned in the table below.
• Flashing heights may be limited. Existing building details (i.e. doors, windows) may not allow for sufficient clearance to provide proper termination above the potential water level (min. 150mm). Detailed consideration of this condition is critical to the integrity of the roofing system.

1) Direct application if the substrate meets the general requirements.
2) The waterproofing system requires the installation of an approved cover board or insulation board
