For International competition and National Championships the minimum dimensions of a single piste are 15M x 4M with a 30 cm surround before any solid barriers. However, these dimensions are frequently altered for club and leisure situations to take account of limited space available. Many club pistes are 12M x 3M.

Pétanque may be played on any surface but grass, because of the roots deflecting the boule, is not recommended. Gravel or hard earth is the favoured surface.
In the UK we try to recreate the dusty squares and areas where Pétanque is played in France, however we, in the UK, tend to have a wetter climate. It is this reason we construct areas similar to gravel driveways so we can play when the weather is inclement.

Construction
To construct a pétanque piste that is satisfactory to play on in all seasons it is first necessary to select a reasonably well drained area.

The topsoil should be removed to a depth of 6-8 inches (150 - 200 mm) and a layer of hard-core, brick rubble, stone etc. laid in the bottom.  This should be compacted down to approx. 4 inches (100 mm) thick using a Wacker plate or Roller. The area can now be filled with crushed quarry stone 1 1/2 inch down to dust all in.   This is known as type 1 sub base or scalpings. A heavy roller over this, if it is not too dry, will provide a hard firm surface. However, if played on at this stage the large stones will come to the surface. The area will need subsequent rolling and watering to settle the stones down. A shower of rain (hose pipe ) will be beneficial. 

A solid surround of some sort is usual to a playing area to prevent boule that are out of play rolling considerable distances or causing injury. A wide variety of items are seen used for this purpose, most commonly, old railway sleepers, planks, old kerb stones, old telegraph poles. etc. Depending on the size of the edging available it can be incorporated at any stage after digging to leave 4-6 inches (100 - 150 cm) above the finished playing area.

Once the material so far included has been very well compacted a thin layer of quarry dust 1/4 inch to dust should be spread over the area and rolled again and again.

Settling
The ideal surface will take some time to appear as some pistes take time to settle. During the first year you may find soft areas appearing where frequent boule landing takes place. The surface can be maintained by raking the surface with a wire leaf rake. Care should be taken to try to place the jack in differing areas of the piste. Boule make good wackers for the surface. Any large stones working their way to the surface should be removed from the area.

The overall surface should not be "Billiard Table " level as this is Pétanque not Bowls. A certain amount of thought should be needed to cope with the odd small irregularities in the surface. Anyway, the home team deserves some advantages for all the hard work they have put in building the playing area!

 
Common Construction Mistakes
A piste should be an ever changing surface. As the above structure compresses with rolling, whacking, rainfall, general play and the constant walking up and down or the players the boule should roll faster the game should become more difficult. The result will be, as a player you will get better and as a piste you will have great home advantage. If the wrong topping is used, i.e. pea shingle or large gravel stones the topping will remain floating on the surface and take years to break down into smaller gravel. It will pile up at both ends as it moves when boule land.

 
Many constructors put far to much topping on their piste. It can make playing easier but shooting will be difficult as the pointed boule dig in. Some teams actually put excess topping on pistes knowing it stops shooters effectiveness. Bad Sports!

 
Large stones used as topping can be dangerous.
A membrane laid on grass and covered in gravel can be a simple construction technique. Not really suitable as the gravel bounces away from the boule landing area and of course this piste will never bed down.
I hope this give a guide for those looking to install a piste in their gardens or play areas.  Enjoy your Pétanque.
