A 2mm corrugated polypropylene protection board, 1805mm x 1210mm, laid over waterproofing membranes before backfill, screeds, or other trades get on site. It takes the impact and puncture load so the membrane underneath does not.
Light enough to carry and cut with a knife, tough enough to survive a build. Tape the joints so sheets do not shift, and leave it down until the surface work starts.
Frequently asked questions
How is Corflute Protection Board applied?
Simply place the board directly over the waterproofing membrane before backfilling or applying pressure. For vertical applications, use tape or adhesive to secure it in place.
What level of protection does this board offer?
The 2mm corrugated polypropylene structure offers high resistance to puncture, impact, and abrasion. This protects waterproofing membranes in heavy-duty construction environments.
Is this protection board compatible with all waterproofing membranes?
Yes, it is chemically inert and non-reactive. This makes it suitable for use with most sheet and liquid-applied waterproofing membranes without risk of degradation.
How should Corflute boards be stored to prevent warping?
Store boards flat in a shaded area. To correct minor bending, lay flat with weight on top. Avoid storing near heat sources or in direct sunlight to prevent deformation.
Applications and benefits
| Application | Key benefit | Primary trades |
|---|---|---|
| Temporary protection of waterproofing membranes | Prevents punctures and impact damage during backfilling and subsequent construction phases, avoiding costly membrane reapplication. | Waterproofers, general builders |
| Floor and wall protection during site fit-outs | Shields finished surfaces from traffic, spills, and material drops, maintaining project quality and reducing rework. | Fit-out contractors, tilers, plumbers |
| Protection for slab preparation and joint detailing | Guards delicate areas or freshly prepared surfaces from accidental damage before final coverings are applied. | Concreters, tilers |
How to apply Corflute Protection Board (1805mm x 1210mm x 2mm):
- Ensure membrane is fully cured before applying protection board
- Lay sheets flat over membrane surface, overlapping edges slightly
- Use compatible adhesive tape or spot fix with sealant if vertical application is required
- Cut to fit corners or penetrations using a utility knife
- Proceed with backfilling or further site works as needed
Product limitations
- Not for: Long-term UV exposure as a permanent barrier. The material is not designed for continuous outdoor use without cover.
- Not for: Use as a structural load-bearing surface. The board is for protection, not support.
- Risk of: Warping under excessive heat if not stored flat or exposed to direct sunlight for extended periods.
Safety and handling
Personal protective equipment
Cut-resistant gloves are recommended when trimming or cutting the board to prevent injury from sharp edges.
Ventilation
Ventilation is not specifically required as the material is non-toxic and does not emit hazardous fumes.
Handling
Carry boards flat to avoid bending or creasing. Cut edges can be sharp.
Storage and disposal
Store boards away from open flame or direct sunlight to prevent degradation and warping. Dispose of damaged boards in general industrial waste. Corflute is recyclable in many areas; check local council guidelines for recycling options.
Substrate guide
This guide outlines the surfaces Corflute Protection Board is designed to protect and how it interfaces with them.
Waterproofing membranes (liquid-applied and sheet)
Surface prep: Ensure the membrane is cured or adequately set according to its manufacturer's instructions. The protection board is placed over the membrane.
Primer: Not required for membrane protection. Secure vertically with tape or adhesive if needed.
Concrete surfaces
Surface prep: Concrete surfaces should be cured and clean. The board provides temporary protection on these surfaces.
Primer: Not required.
Timber formwork
Surface prep: Ensure timber formwork is stable and free from large debris that could affect board placement.
Primer: Not required.
