The UK is trapped in a costly repeat-repair cycle, in excess of 1.5 million repairs a year with a cost of over £150m.  Rising compensation claims.  The status quo is failing the tax payer and the carriageway.

"Pothole works 'cost £18.6bn' The cost of fixing all the potholes on local roads in England and Wales would be an estimated £18.6bn, the industry body that oversees road surfacing has warned."

"Now pothole pay­outs are set to rocket, say insurers. POTHOLE insur­ance pay­outs are set to hit record levels – with one firm set­tling more claims in Janu­ary than dur­ing the entire pre­vi­ous six months."

"Attacks on workmen by motorists surge as anger grows...Workers are being sworn at, spat at and even punched amid growing delays in fixing potholes, industry leaders revealed."

The Traditional Thinking
Surface Failure

Cross-section diagram illustrating the myth of pothole surface failure, showing downward arrows representing traffic pressure on a cracked carriageway.

The Reality:
Subsurface Hydraulic Failure

Diagram showing the reality of subsurface hydraulic failure, where a vehicle tyre forces trapped water upwards, debonding the pothole repair from beneath.

Potholes are not a surface material problem; they are a water and pressure management problem.

Passing vehicles force trapped subsurface water upwards, debonding the patch from the inside out.

PRODUCT ANATOMY

Before

Illustration showing trapped subsurface water creating high hydraulic pressure beneath a road surface before a pothole repair.

Water under high pressure is pushed upwards.

Install

A road worker placing the Pave-Vent engineered drainage insert into a prepared pothole prior to resurfacing.

Place relief insert into pothole.

Relieve

Cross-section illustration of the Pave-Vent insert safely venting trapped water to the road surface to relieve hydrostatic pressure.

Excess water pressure safely vented.

Prolong

The Lightbulb Moment!

Innovation often strikes in unexpected places. For PaveVent™, the fundamental breakthrough was inspired by observing the mechanics of a simple child’s catching toy. This sparked a crucial realisation: the highway maintenance industry was fighting the wrong battle by treating potholes purely as a surface material failure. In reality, the true culprit is subsurface hydraulic pressure. Passing vehicles act like massive hydraulic pumps, compressing saturated ground and forcing trapped water upwards to relentlessly destroy standard asphalt patches from the bottom up.

How does it work?

Initiate an Evidence-Based Pilot

A low-risk, controlled trial for UK local authorities. Evaluate durability, repeat failure rates, and whole-life cost impacts without long-term procurement commitments.

1 Status Quo £100 avg. repair cost / 12-month lifespan = £100/yr annualised.
2 With PaveVent £115 total cost / 24-month lifespan = £57.50/yr annualised, 42.5% reduction.
