Concrete technology is a very specific science. When constructing with concrete, factors such as subsoil drainage, suitablity of subsoil, compaction of soil, slab substrate, steel reinforcement, form quality and the concrete and its finishing must be addressed.

All concrete is not equal. Each and every application must be engineered. Most ready-mix concrete companies will compile a "concrete mix design" to meet your specific needs.

The basic elements of the design should include the following:

Cementitous Factor

Cement lbs. per yard                             Sand lbs per yard 

Aggregate size and lbs per yard                    Water gallons per yard

Polyheed, darex and other additives                Water/Cement Ratio 

Slump                                         Air content entrapped

Last but not least, the quality of the skating surface is the hands of the mason and his trowel. Etched and broom finishes are not suitable skating surfaces. Concrete should be periodically inspected for cracking, spalling and surface damage. Concrete is a great product for skateparks, but be careful
