It is very important to have an excavator capable of doing arena work, because installing an arena requires precision. The removal of the top soil and grading of the sub-base can be easily done, but when installing different base materials and drainage it is paramount that they are installed correctly. FootingFirst™ recommends hiring an arena expert installer.
A free-draining base will provide the very best drainage for an arena. This can be installed in many different ways, using varying sizes of rock and levels of pitch, depending on which system is being applied.
Pitch is very important for a traditional arena. Any arena requires enough pitch to run the water over the surface, but not so much that it would cause erosion of the surface.
