Infield drainage is
typically a topic for discussion anytime I give a presentation on infield
mixes, grades, etc. So, when the J&D Turf team was tasked to remedy
an infield drainage issue at University of Indianapolis, the team chronicled
their work with photos.
Before we get to the photos, lets lay out a couple of items in regards to infield drainage:
1.
Do NOT install drain tiles under the infield mix. The
infield mix should be engineered and maintained to eliminate downward movement
(percolation) of water. All water during rain events should run off the
infield.
2.
Due to item #1, positive surface drainage must be achieved on ALL
infields. For baseball and softball, surface drainage should be between
.5% and 1%. Keep in mind, if a softball field does not have sod in front
of dugouts, surface drainage should be NO MORE than .5%. Does your
infield conditioner run off your infield? Chances are, the infield has
surface drainage exceeding the limits listed above.
3.
Purchase and manage a good infield mix. Be careful when purchasing
infield mix! To learn more about infield mixes, click HERE and HERE.
So, lets explain what the
existing conditioners were at Baumgartner Field at University of Indianapolis:
1.
Native soil.
2.
Due to existing topography, the grade falls from the RF foul pole
to the 3rd base dugout.
3.
Bluegrass/Ryegrass surface
4.
Infield Mix - Dura Edge Classic
5.
Conditioner - Diamond Pro Professional Calcined Clay
6.
Mound Clay - Dura Pitch Mound Clay
7.
During rain events, water would run from RF under the tarp and
become trapped.
The solution:
Install a six-inch wide
trench:
Next, installation of a 4 inch perforated drain tile and 6 inches of USGA drainage gravel.
Then, installation of 6 inches of USGA rootzone sand all the way to the surface. Then the existing sod was re-installed. DO NOT seal off drain tiles by placing native soil over drainage gravel.
Finally, an edger was used to run across the trench/slit and expose 3 inches of the sand. The bluegrass will grow into the sand.
The location of the drain tile while the tarp is on the field.
Lastly, the field ready for play the day after installation.
Mission accomplished!
Best of luck to the Lady Greyhounds as they begin the road to the D-II College World Series.

ReplyDeleteSad as usual seeing not one normal person commenting on this blog.
ReplyDeleteAnd there is a likelihood that both cricket players, baseball players and softball players all violently hit home runs at exactly the same distance even though golfers would violently hit golf balls off the teas further than baseball players, cricket players and softball players. By the way softballs are not soft. So why bother calling softballs "soft" for anyway?
