'Reduced Dig' Installation - GRASSED SURFACES

Posted by Muhammad Fareed Sunday, June 21, 2009

1. Cut the grass closely to the surface or where necessary remove the turf and topsoil to a depth of <75mm and dispose of all debris. Level the formation layer and lightly consolidate.
2. Install edge retaining boards or kerbs if required
3. Place a layer of Boddingtons geogrid stabilisation mesh or geotextile fabric on the formation layer and ensure that it is flat to the surface by pinning as required.
4. Place a 35mm thick layer of 5-14mm diameter gravel / aggregate evenly over the geogrid. The geogrid must not be allowed to become exposed above the gravel / aggregate layer.
5. Place the Bodpave® grass pavers onto the screeded gravel / aggregate layer. Connect the pavers using the ground spikes and loops, progressing over the area in rows. Use protective gloves to avoid abraisions.
6. Pavers can be cut using a hand or power saw fit around obstructions and curves. Cut pieces which are less than half the original size should be avoided where possible. Pavers can be firmed in place using a light vibrating whacker plate if required.
7. Fill the pavers with the specified propriety rootzone. Finished levels should be 5-7mm below the top of the cells after settlement. Do not overfill the paver cells. A light vibrating plate can be used to consolidate the pavers and to settle the rootzone infill if required.
8. Rootzone must be a free-draining structurally sound sand:compost or sand:soil blend. This is a nominal propriety blend of 60:40 or 70:30 ratio. Self blending is not recommended.
9. Carry out a normal seeding, fertilising and watering programme. A very light top dressing may be applied to just cover the seed and to provide adequate germination conditions. Do not overfill the paver cells. Alternately thin-cut turf can be rolled into the surface if required.
10. The surface may be trafficked immediately, but it is preferable to allow the grass to fully establish prior to use.
