BASE

The base is the foundation of your arena, and like the foundation of a house, it is the most important part. If the base is compromised it will become more complicated to repair, and often times it needs to be completely re-done or added to in order to correct the problem. Therefore, installing a proper base is paramount.  If you determine that your base has been compromised then it will need to be addressed. The cost of a new base starts at approximately $2/sq ft. 

TIP: If your stonedust has been compromised you might find the larger stones from the base coming through into your footing.
