8.1.        GENERAL SPECIFICATIONS
Samples
Supply soil testing reports as per Soil section 18.1 in the frequency specified.

Garden Soil specification
All soil types are specified in the soil specification section 18.2 in this specification.

All garden soil is to be consolidated yet not compacted. All soil is to be installed to heights which allow for
settlement, so that at off-maintenance all surface levels are to those detailed in the documents.

All garden soil is to be free of deleterious material such as sticks, tree roots, stones, weed seeds and is to be
non-toxic to living organisms. On-structure planters are to be free from any debris/rubble immediately prior to
drainage and soil placement.

Evenly grade between reduced levels i.e. (spot levels).

Inside Planter Walls
Wrap the waterproofing up the inside of the planter walls and/or and building façade. Use a protection board
to protect the waterproofing membrane. Lay nonwoven, needle punched filter fabric to base and up the sides
of the planter walls. Secure filter fabric between wall body and internal cladding (cladding to be min 150mm
depth). If rendering is use apply 150mm wide steel flashing in the same colour as rendered finish to fix filter
fabric to wall. Fix flashing through neoprene washer and seal flashing with flexible sealant on the top.

Turf pattern / joints
Lay a perimeter strip and then lay infill sods with staggered tightly butted joints. Dress joints and edges with
soil (the same soil as used under turf) as required to prevent the turf drying and to provide a smooth
transition to adjacent levels.

Watering
Water twice daily for the first week after laying to ensure rapid root establishment.

Top Dressing
Spread 10mm depth of medium washed river sand approximately 6 - 8 weeks after laying turf.

Quality
All turf must be AusGAP certified turf.
