Pendulum Test Value (PTV) is a measurement used to assess the slip resistance of a walking surface. It is obtained using a pendulum testing device that simulates the action of a person’s heel striking the ground. The higher the PTV, the greater the surface’s resistance to slipping.
PTV is widely used in the construction industry to evaluate the safety of footpaths, pavements, commercial entrances, and other pedestrian areas. While it is not a legal requirement for every domestic resin driveway, it is an important indicator of how safe a surface is, particularly in wet conditions.
For homeowners, a good PTV can provide added confidence that a resin bound driveway will remain safe to walk on throughout the year.
How Is PTV Measured?
A pendulum tester swings a rubber slider across the surface and measures the amount of friction created. The result is recorded as the Pendulum Test Value (PTV).
In general:
- 0–24 PTV: High slip risk.
- 25–35 PTV: Moderate slip risk.
- 36+ PTV: Low slip risk in most conditions.
The final result depends on several factors, including the surface texture, the type of aggregate used, and whether the surface is wet or dry.
Why Is PTV Important for Resin Driveways?
One of the advantages of a resin bound driveway is that it can provide excellent grip when installed correctly. The exposed natural aggregate creates a textured surface that helps improve traction without being uncomfortable to walk on.
Combined with its permeable design, which allows rainwater to drain through the surface rather than pooling on top, a resin driveway can remain safer underfoot during Ireland’s wet weather.
Although most homeowners will never need to request a PTV test, understanding the concept helps explain why professional installation and the correct choice of aggregate are so important for long-term safety.
How Resin Driveway Ireland Delivers Safe Walking Surfaces
We install resin bound driveways using high-quality UV-stable resin and carefully selected natural aggregates that provide a durable, slip-resistant finish. We also ensure the surface is laid evenly and over a properly prepared base to maximise both safety and performance.
Our goal is to create driveways that not only look great but also provide reliable grip in everyday use, helping homeowners feel confident walking on their driveway in all seasons.
