TURF-TEC 6 and 12 INCH INFILTRATION RINGS
INSTRUCTIONS (IN7-W & IN8-W)
Outline of UsesThe Turf-Tec Infiltration Rings were specifically designed to give infiltration
readings directly on site. They can give you a reading on the rate of water percolation through grass,
thatch, mat and soil, as well as directly on bare soil.
Use a heavy jack under the back end of a truck to drive
rings as an alternative to the sledge method
1. Position the Turf-Tec IN6-W driving plates over the IN8P-W - 6 and 12 inch Infiltration rings,
so the center bar is in the center of the two plates as shown.
2. Center a suitable wood block across the Turf-Tec IN6-W Steel Driving Plates.
3. Center a jack on the driving plate or wood blocks. Place the top of the jack and the assembled
items vertically under the previously positioned end of a truck
body and apply force to the ring by means of the jack and truck
reaction.
4. With a rubber mallet, tap near the edges, or near the
center of the ring.Slight tapping and vibrations will reduce
hang-ups and tilting of the ring.
5. Check the rings with the level, correcting the attitude of
the rings to be vertical, as needed.
Reliability of testing and reducing variables
Saturated test (The most reliable test method)
The most reliable test method for measuring infiltration is called a saturated test. This method is
performed by placing the Turf-Tec Infiltration Rings directly into the soil to be tested and filling the
rings 2-3 times, allowing the water to infiltrate into the soil between fillings. Once the soil is saturated,
you can perform the test.
Moisture Sensing (The quickest test method)
Another reliable method for testing infiltration is to use a Moisture Sensor. The readings of the soil
to be tested using a Turf-Tec Moisture Sensor should be taken at one, two, three and four inch
levels, and recorded. The infiltration test can then be performed on that area. This method should
be repeated for each test area. In addition, be sure the Moisture Sensor readings are in the exact
same range before testing the same area the next time it is to be tested for infiltration. This will
eliminate any variables and still produces a reliable test.
