The INVERT  Level of a pipe is the level taken from the bottom of the inside of the pipe
as shown below. The level at the crown of the pipe is the Invert level plus the internal
diameter of the pipe plus the pipe wall thickness.

Don’t let your rod get crooked.

The InvertBoot solves the age-old surveyor’s issue of recording the invert on
a culvert or drain without the need to angle your surveying rod.

The InvertBoot has been created to be easily fitted on the foot of the most
popular Grade Rods such as the Crain SVR 25-Foot Fiberglass Grade Rod.

With the InvertBoot the Surveying or pipe laying technician can find the invert
on as-built Infrastructure, Drainage & sanitary surveying projects as wells as
new development land surveying projects.

InvertBoot is a professional grade tool that will stand up to daily commercial use.
If your project demands accurate, high-quality land surveying equipment that can
help find the invert, InvertBoot is the tool to use. InvertBoot is commercial grade
surveying equipment that is much needed in the industry.
