Flat roofs naturally move — through seasonal temperature changes, structural settling, material ageing, and wind uplift. A roofing system that cannot accommodate these movements risks splitting, delaminating, or failing prematurely. TriRoof HPX was engineered to eliminate these vulnerabilities.
One of HPX’s defining characteristics is its ability to stretch up to approximately 300% once fully cured. This level of elasticity is significantly higher than traditional rigid systems, giving HPX the durability needed to handle real‑world building movement.
HPX’s elastomeric behaviour ensures the membrane stays intact and watertight, even under dynamic conditions.
Movement leads to stress — and stress leads to cracks.
By stretching rather than resisting movement, HPX greatly reduces membrane failures.
HPX performs exceptionally well on:
When combined with optional reinforcement, HPX becomes even more resistant to deck instability.
HPX’s flexibility advantage is paired with ease of use:
Its cold‑applied formula ensures consistent elasticity throughout the cured membrane.
For buildings that move — which is nearly all buildings — TriRoof HPX provides unmatched flexibility and long-term performance. It’s the membrane that adapts, protects, and lasts.
TriRoof HPX is an elastomeric liquid membrane designed to flex with building movement rather than resist it. Unlike rigid systems that can crack or split, HPX maintains integrity by stretching and adapting to structural changes.
TriRoof HPX can stretch up to approximately 300% once fully cured, providing exceptional elasticity and durability in dynamic roofing environments.
Flat roofs experience constant movement due to temperature changes, structural settling, and environmental factors. A flexible membrane like HPX prevents cracking, splitting, and long-term failure by accommodating this movement.
TriRoof HPX is ideal for:
Yes. Its high elongation allows it to absorb stress and movement, significantly reducing the likelihood of cracks forming in the membrane over time.
Yes. It is a ready-to-use system that:
While HPX performs well on its own, optional reinforcement can be used to further enhance resistance to structural movement and substrate instability.
Thanks to its elastomeric properties, HPX maintains long-term flexibility and waterproofing performance, even as the building ages and continues to move.
Absolutely. Its flexibility and ability to adapt to existing substrates make it particularly well-suited for refurbishment and overlay applications on older roofs.
Yes. By remaining flexible and crack-resistant, HPX ensures a watertight seal even under continuous stress and movement.
