Above Ground Or In Ground Foundation- How Do I Decide?
Jan 18, 2019


We install truck scales above ground with approach ramps, or in a pit, level with the surrounding terrain. The type of scale and foundation installation is dependent upon the location and the traffic pattern needed. Below is a comparison chart for the two types of foundations. Check out the chart or contact the Quality Scales Unlimited sales team to see what truck scale will work best for you!
