IKO Hyload Protection Board - Structural Waterproofing - Polymeric board for protecting membranes

IKO Hyload Protection Board is a tough, flexible polymeric board for protecting membranes against damage caused by pedestrian/vehicular traffic, and abrasion caused by backfilling.

Features and benefits:

• Rot resistant - provides permanent protection.
• Resistant to contaminants including the alkali attack contained within normal soil conditions.
• Flexible, robust and easy to cut/ fold.

Construction:

– Horizontal:

• In normal conditions, the board should be loose-laid with butt joints onto the area to be protected.
• Joints must be over-taped using self-adhesive vinyl tape.
• This reinforces the joint and helps to secure the board in place whilst also preventing aggregate fines being washed down on to the protected surface.

– Vertical:

• Can be temporarily secured to the vertical surface using Hyload DPC Jointing Tape.
• Three strips of tape should be positioned parallel to the longest side and equidistant across the board. Remove the silicon release paper and press the board into position.
• These methods are sufficient to hold the boards in position whilst back-filling.

Change in length - dry at 80°C:

• After 24 hours: -0.4%.
• After one week: -0.4%.

Change in length - wet at 80°C:

• After 24 hours: -0.4%.
• After one week: +1.4%.
