HPX Waterproofing Put to the Test - With a Cardboard Box!

HPX Waterproofing for Flat Roofs

Demonstrating the strength of HPX in the most unexpected way - because real performance speaks for itself

When it comes to HPX Waterproofing for Flat Roofs, performance is everything. At Tricel Composites, we understand that roofing professionals need a solution that’s fast, reliable, and proven to work in real-world conditions.

To demonstrate just how effective HPX really is, our Technical Sales Representative, Adam, took a creative approach…

The Test: Cardboard vs. Water

Cardboard is famously not waterproof. It absorbs water, warps, and breaks down quickly when exposed to moisture. So what happens when you coat the inside of a cardboard box with HPX and pour in a full bucket of water?

Absolutely nothing.
No leaking. No dripping. Just reliable, watertight protection. 

This simple yet powerful demonstration shows just how impenetrable HPX becomes once applied — even on a surface as fragile as cardboard.

Watch the full video of Adam’s test below. 

Why HPX Waterproofing for Flat Roofs is a Game Changer.

While the cardboard box was just a visual test, HPX is engineered for real-world roofing applications. Here’s why it’s trusted by professionals across the industry:
