Rubber buffings are pieces of recycled tire rubber produced during tire processing. Flexirocks supplies two types of underlayment for commercial buyers: sieved 4-12 mesh clean buffings with minimal dust and a playground pellet. Select the type, packaging and binder system based on the project specification and intended application.

Build a complete surfacing material order

For playgrounds, contractors can pair a specified rubber base material with polyurethane binder and colored TPV granules for a wear layer. Material selection and coverage depend on the tested system, layer thickness and installation requirements.

Product details and documentation

Before ordering, confirm current particle distribution, tire content, packaging weight, availability and any test documentation needed for your project. If the buffings will be used in a playground system, evaluate performance of the complete specified surface rather than assuming a base material carries a fall-height rating on its own.

Rubber buffings FAQ

What is the difference between 4-12 mesh rubber buffings and playground pellets?

The 4-12 mesh product has long been the industry standard in playground underlayment and is what most installers are most familiar with.

Playground pellets were created much more recently and because of the shortages in the buffings supply market.

They both function the same however installers tend to prefer the buffings due to familiarity.


Are the buffings and pellets made from recycled tires?

Yes. Both products are derived from used tires.


Are rubber buffings or pellets appropriate for playground cushioning?

Absolutely. In fact many playgrounds are certified for fall height hazards using both products. They can be used in the base layer of a properly designed surfacing system. Required thickness and impact performance depend on the complete system and its testing.
