The construction of a tennis court itself requires attaching special care to the foundation on which the playing surface will rest.
The first phase of earthworks for a tennis court consists of creating an excavated platform, flat, stable and set at 3 cm in accordance with standard NF P90-110. Depending on the topography of the land, it may be necessary to make a riprap. This is essential when the slope of the bank is important. Rip-rap significantly reduces the height of an embankment.
In the event of the presence of clay, a replacement layer, also called a consolidation layer, will be placed in order to restore the existing ground to the necessary bearing capacity for the construction of the court. This is to avoid the phenomenon of shrinkage – swelling which is detrimental to the stability of tennis.
A drainage system is placed on the platform, to allow the recovery and evacuation by a collector of rainwater. Depending on the topography of the tennis court, it will be necessary to provide for the collection of runoff water from outside the court.
The second phase is to build the infrastructure which is a foundation layer. It consists of the supply and the installation of a carefully regulated filter blocking.
Once these operations have been carried out, it will be possible to pour the porous concrete slab.
Depending on the nature of the future tennis court, and after a geological study, a replacement layer will be placed in order to restore the existing ground to the necessary lift for the construction of the court.
This consolidation layer consists of using a 0/60 quarry material over a thickness of 0.25 m, carefully adjusted and compacted to allow the clay to maintain an almost constant humidity and thus avoid the phenomenon of “shrinkage – swelling. detrimental to the stability of tennis.
Drainage consists of creating trenches in which drains will be laid connected to an exterior collector at the end of the court. This drainage is essential, it collects all the rainwater from the tennis court.
