Evidence-Led Pothole Relief.
De-risking the innovation for UK infrastructure specifiers
From Insight to Reality.
The device is a physical, tested compnonet ready for controlled real-world pilot deployment.
University-Backed
Supported by physical testing and ongoing collaboration with engineering experts at Ulster University and the University of Nottingham.
Underpinned by Science
Validated by an independent physics paper exploring subsurface hydraulic dynamics and the venting mechanism.
Will a hollow device simply crush under the weight of an HGV?

Functional Proof: The Physics of Venting
Subsurface Mobilisation (Hydraulic Pumping Test)
Under saturated conditions, applied pressure mobilises water and disperses fines. Water visibly migrates away from the central area, demonstrating active subsurface drainage.
Surface Ejection (Load -Induced Displacement Test)
Immediate vertical ejection of trapped water. The device successful converts downward compressive mechanical load into a defined, upward vertical flow path.
Core Takeaway: Mechanical load activates the vent. Destructive hydraulic pressure is safely redirected away from the base layer, preventing debonding.
Material & Environmental Resilience
NYL-30 variant demonstrates superior load-bearing performance, achieving a peak load capacity of ~15–16 kN.
Maintains structural integrity longest, providing high strength and stiffness.
When saturated and frozen, expanding water is forced upward through the device and discharged safely onto the asphalt surface.
Result: Zero explosive cracking or lateral displacement within the asphalt body.

PaveVent™ Testing & Validation FAQs
Has the PaveVent™ device been independently tested?
Yes, the PaveVent™ pothole relief device has undergone rigorous independent physical testing, including a Road Load Test conducted at Ulster University that subjected the engineered inserts to 100,000 cyclic wheel passes with no structural deformation.
Does the PaveVent™ insert crack during freeze-thaw cycles?
No. Official freeze-thaw testing demonstrates that the device safely channels expanding ice and water vertically out of its top grate onto the road surface, rather than allowing it to expand laterally and crack the surrounding asphalt.
Can the PaveVent™ device withstand heavy traffic loads?
Yes. Compression testing confirms that the high-strength NYL-30 material variant of the PaveVent™ device achieves a superior load capacity of 15-16 kN, maintaining its structural integrity without failing under heavy vehicular loading.
How is the venting action functionally proven?
Functional testing, including Load-Induced Water Displacement simulations, physically proves that the downward mechanical load of passing traffic actively forces trapped subsurface water to safely eject vertically through the device, actively relieving destructive hydraulic pressure.
