TECHLINE AS™ IN TURF (SDI):
Refer to Table 1 for correct drip discharge, drip and dripperline spacing.
Refer to Table 1 for correct Techline AS™ burial depth.
Ensure that all dripperlines are installed at a uniform spacing and at an even depth.
Any variations may cause a variation in water application rates.
Always use the GRID layout for SDI systems.
Techline AS™ can be laid on top of a level surface and have topsoil applied to it at a
uniform depth.
Techline AS™ can also be inserted into the ground with a plough. Again ensure that it
is installed at a uniform depth.
Install a Techfilter to protect the system from root intrusion.
TECHLINE AS™ IN NEW SODDED TURF:
Follow Table 1 General Guideline’s recommendations for turf.
Bury the Techline AS™ to the depth specified in Table 1 ensuring that it is laid at an
even depth.
In areas where mechanical aeration will be used, bury the Techline AS™ 150mm below
final grade and ensure that aeration does not exceed 100m in depth.
When installing the sod:
o It is important that the final grade is smooth, ensuring that the sod makes solid
contact with the soil.
o Properly “knit” the edges together
o Roll the sod to ensure good contact.
If the irrigation system is automatic:
o Set the zone to operate several times per day (check local water restrictions)
o Provide additional overhead irrigation until roots establish
Once you can not pull the edges of the sod up, discontinue overhead watering.
Irrigate on a daily or every-other-day basis (check local water restrictions)
NOTE: Temporary overhead irrigation may be required to irrigate sods/turf for the first 7-10 days
until root establishment occurs and SDI becomes effective.
TECHLINE AS™ ABOVE AND BELOW GRADE:
Techline AS™ is designed to be used in a variety of ways:
o It can be laid on the surface (it’s UV resistant) and held in place with Asta Hold Down
Stakes.
o It can be laid on the surface, staked into place and covered with mulch, or
o It can be buried below grade.
NOTE: When using Techline AS™ above grade with stakes, use enough stakes to firmly hold
the dripperline in place.
