Making a Grade Verification Lath
Verifying grade requires measuring depth of cut from the Sonic
Stringline. Because the hubs are offset from the edge of road and the
Sonic Stringline is a predetermined "hike-up" above Finished Grade,
a simple tool called a "Grade Checking Lath" can be constructed.
This can be easily done using lath, a level bubble and simple hand
tools.
In this example assume that the hub offset from the edge of road is 1.5
feet and that the "hike-up" is 2.0 feet. Construct a Grade Checking
Lath as shown below.
