An outdoor billiards table comprises supporting legs, a supporting frame, a playing surface and side and end rails formed from concrete. Main levellers are disposed between the supporting frame and the supporting legs to level the table, and slate levellers are provided along sections of the playing surface for levelling and to compensate for warpage. The playing surface is composed of a mixture of non-shrink construction grout containing graded siliceous aggregate, water reducing agents and fluidizing agents, portland cement and synthetic fibres and is cast on plexiglass for a glass-smooth finish.

Why it's free to use
- Filed July 31, 1992 and granted April 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 31, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 31, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
