Drainage Mapping
VUI can locate and map the drainage system under your greens and fairways providing
both depth and precise location.  The maps are ideal for finding clean-outs to attach
subsurface vacuum and drainage systems.  Branches and pipe junctions are clearly
identified and the true elevation of the entire system can be measured to confirm a
consistent and proper angle for optimum drainage.

Irrigation Mapping
Lines can be replaced or upgraded with minimum excavation and disruption to the course.

Engineered Soil Thickness Assessment
VUI can measure the depth of the engineered soil layer underneath your greens.  We
provide a map clearly showing the depths at regular intervals.  Areas where the layers are
thicker or thinner than ideal can be highlighted.  Irregularities or foreign objects can also be
shown.

Topographic Mapping
Determine the topography of your greens and fairways.  Find low spots where water may
collect.  Help plan restoration or drainage projects.  The maps can also be rendered in 3-D
for display on promotional materials, websites or yardage books.

Clogged or Damaged Pipes
If you suspect that a drainage pipe has been damaged or clogged, VUI can investigate
using our radar systems.  Separated pipes and water-filled plastic pipes can often be
identified and located.

Utility Mapping  (visit our Utility Locating and Mapping Web Site)
Locate underground utilities around your buildings, parking lots or entering/crossing your
property.  Ideal for expansion projects or to minimize disruption or damage when doing any
excavation on your property.
Our underground mapping and locating services use advanced 3-D array ground penetrating radar (3-D GPR) technology and
software.  This technology creates a seamless "picture" of the underground similar to a medical image such as an MRI or CAT
scan.  We use this detailed image to create radar generated as-builts showing the underground drainage lines and other
objects in relation to the green edge and nearby surface features (sprinkler heads/valves, drains or other objects).  Each pipe
is labeled with its depth below surface (can also show absolute elevation).  Results can be presented as printed drawings
and/or in digital format such as CAD or Portable Document Format (pdf).

Our equipment can safely move across a green without damaging the surface due to its light weight.  On average, we can map
3-5 greens per day without closing holes to golfers.  If play is suspended on the greens being mapped, 5-8 greens can be
completed per day.
