2.3 Allow at least 12 weeks for plants to firmly establish in nurseryenvironment
2.4 Orientate plants to growth from a wall by progressively tilting
VGM modules from horizontal to vertical over the 12 weeks
3. Prepare Wall for VGM Installation
3.1 Prime RC wall and/or construct framework (including
waterproofing, painting, welding, etc) according to project
requirements

3.2 Vertical beams of framework MUST correspond prec isely with
VGM width for pilaster installation
3.3 Erec t staging for work on high wall
4. Install Pilasters
4.1 Take vertical and horizontal wall measurements to determine
position of first pilaster (anchor rails) according to projec t
requirements
4.2 Drill holes at all securing points to required depth using drill bit
diameter corresponding with anchor used. Blow out dust and
fragments
Beam does not correspondwith VGM width
Setting Tool
Threaded Wedge Anchor
Stainless Steel Bolt
Stainless Steel Washer
Beam does not correspondwith VGM width

4.3 Pilaster positions MUST register with width of VGM and all
pilaster mounting slots align
4.3
Use assembled VGM modules to assist in accurate alignmentof pilasters
4.5 Sec ure pilaster with stainless steel Stud or Wedge anchorstighten with torque wrench for RC wall or sec ure with stainless
steel nuts and bolts for a constructed framework accordingly
Assembled VGM modules assist in alignment of pilasters

5.3 Install irrigation system, including controller, solenoid valve,pressure regulator, filters and valves linked to fertiliser supply,
to projec t requirements or as advised, to deliver irrigation and
fertiliser at programmable intervals for controlled durations
5.4 A rain sensor (optional) may be installed to overrideprogrammed water release when the green wall receives
sufficient water from rain
