Concrete Skateparks are best

Concrete is the only long term sustainable solution for outdoor skateparks. 

The advantages of concrete are:

- Fast, smooth performance
- Lowest noise emissions
- Fireproof
- Vandal resistant
- Very low maintenance
- Rust free (no re painting etc)
- Weatherproof

However, concrete does require experience and knowledge to produce a professional finish and a long lasting product.

As for the others

Wood : Decays and burns

Steel : Unscrews, is noisy and gets stolen

Tarmac:  Sinks next to ramps, goes soft and sticky in the heat

Basically Concrete:  Is quiet, it lasts and it is great to ride.
