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.

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.
Why InvertBoot?
The InvertBoot solves the age-old surveyor’s issue of
recording the invert on a culvert or drain.Which can be vital in
determining the allowable headwater depth (AHD) on a project. The InvertBoot has been created to be easily fitted on the foot of the standard Grade Rod.
The InvertBoot Can Help the surveying Field Technician in finding and calculating a few of the following known site conditions.
The flowline at the inside lowest point of a culvert cross-section.
- Allowable headwater depth (AHD)
The allowable depth of water immediately upstream of a culvert,
measured from the invert at the first full cross-section of the culvert.
Design criteria.
- Allowable headwater elevation (AHE)
The maximum permissible depth of water surface immediately upstream
of the culvert at the design discharge, measured from a datum. Note:
datum may differ between software applications; measured from culvert
invert or another datum.
The water surface elevation upstream from a culvert entrance invert,
measured from a datum. Note: datum may differ between software
applications; measured from culvert invert or another datum.
The depth of water immediately downstream from a culvert, measured from the culvert outlet invert.
Measurement from culvert invert, pool, or channel bottom to the water surface.
In the Field, an existing drainage or the need for ditch
relief on a road segment. usually dictates culvert location. The
allowable headwater depth (AWD) is the maximum depth of ponded water
upstream of the culvert inlet measured vertically from the invert and
controls hydraulic design. AWD may be determined by the depth of fill
over the culvert, which is dictated by local topography, roadway
geometry, and standards. Frequently, a headwater (HW) to culvert
diameter (D) ratio is specified, such as HW/D = 1, which places the
allowable headwater elevation at the inlet crown of the culvert.
The choice of pipe material, shape, and size may be fixed by economics,
availability, site conditions (fill, bedrock, bedload), and fish passage
concerns (Gribben 1997).
Site parameters important in the design of culverts include the length
and slope of the culvert alignment, allowable headwater, fill depth, and
effects on inlet geometry. Fill depth is determined by design loads,
local topography, roadway geometry, and standards.
AS-built Survey
Unlike many land surveys, done before buildings or other improvements
are added to the land or after they are complete, as-built maps are used
during the middle of a construction project. As-built maps show
improvements to the land, as they exist at a particular point in time
and with the InvertBoot your surveying technician can easily find the invert of any drain pipe or culvert.
As-built maps may be used for commercial or residential properties
and are crucial in the construction industry from the planning stage to
actual construction and future maintenance.
As-built mapping is conducted several times throughout the duration
of a construction project. Their frequency and number depend on the
scope of the construction project. The purpose of an as-built survey is
to verify to local and state governing agencies that the construction
work authorized has been completed according to the same specifications
set during planning and shown in the site plan and InvertBoot can
Help. The as-built map is most often used to show the building
inspector that a project under construction is conforming to zoning
regulations. As-built surveys may be required for nearly every type of
land project, from roads and trails to utility improvements and building
construction.
An as-built map shows exactly what has been completed to date, a
useful tool in adjusting the schedule of a large construction project.
As -built mapping provides an important tool for managing the building
as it is under construction and after it has been completed, so use the
InvertBoot and collect your invert data with confidence.
