One of the most popular features of these basins is the simplicity with which they can be raised. Every superintendent has dealt with basins that have become too low because of thatch accumulation, or maybe they were just installed a little too low.
With a Perma Basin, there is no need to dig the basin up and reset it. Simply take an additional frame, set it on the existing basin, and you will raise the elevation by 1¾” in less than 10 seconds.
