MELBOURNE EXHIBITION CENTRE DIMENSION A 75 - 100mm 100 - 150mm 200 - 300mm TRAFFIC TYPE Pedestrian Cars Trucks BASE COURSE DEPTH GUIDE NOTE: Base course design will be reflective to the vehicle loads, traffic volume and existing conditions. In commercial installations a civil engineer should be consulted to determine the requirements for the gravel base course with regard to depth and any need for geotextiles. A GRASSINGS - TYPICAL INSTALLATION STEP 1 Remove depth of soil to thickness of base course plus 35mm, to level the compact area to engineer’s requirements. STEP 2 Subject to geotechnical requirements additional base course stability can be achieved by installation of a geotextile below the road base material. STEP 3 Add graded blue metal (10-12mm) base course to designed thickness and compact to test requirements. IMPORTANT NOTE: Top soil must not be inclusive of any clay or fines. STEP 4 Assemble onto prepared base. STEP 5 After laying TURF CELLS, cut around valve boxes, sprinklers, and trees or curbing using cutting pliers or secateurs. Spread fertilisers over sand (NPK blue or any grass starter). STEP 6 Apply clean sharp sand of suitable growing pH value to fill rings, using large broom to leave top of ring exposed, where roll on turf is to be added. Add a further 15mm of top soil for seeding and hydro mulching. STEP 7 For quick lawn establishment - Roll on grass is recommended. On warm days the sand should be wet to reduce temperature and provide a moist base for the roots of the grass. STEP 8 Roll on compact lawn with heavy roller to remove all air pockets around roots ensuring that the roots are set into the sand layer in the rings. Water and fertilise to suit weather conditions. Must not be trafficked before roots are established. 26 75 GEOSYNTHETIC AND DRAINAGE PRODUCTS HOTLINE 1300 866 367  EMAIL  WEB STRATAGREEN.COM.AU During Installation After Completion
