The third type of course is concrete. These courses were constructed in the 1950’s by Paul Bongni who came from Switzerland. Therefore, this type is predominantly found in Switzerland, Austria and southern Germany, but you can find concrete courses all over Europe. There are only 18 types of obstacles and these have the same number on every course.
The courses are constructed in concrete and the borders around them are made of steel. It is quite expensive to build and requires more space than felt courses. The length of the lanes is 10-12 metres, the longest being about 20-25 metres. Even though it is expensive to build, it is very attractive to play and courses often have large clubs and many casual players. You are also allowed to stand on these lanes when you play and it is necessary to be in the right position when you hit the ball. As on the felt courses you should not walk on the lanes.
