• Product reference: Golpla® Pre-Grown • Colour: Green • Material: The Golpla shall be UV stable 100 % recycled Polypropylene (80%) and Polyethylene (20%).
• Size: 640mm long x 330mm wide x 38 mm depth modular laid dimension. Each unit shall have a free surface area available for infill of 94%.
The units shall have 60 hexagonal cells of per unit, measuring 63mm per cell. -
Note.The General Arrangement drawing shows the lay-by to be 3.5m wide, this should be achievable using 5No whole pavers and 1No. 1/2 paver.
• Subbase [To be confirmed by engineer but manufacturers recommendations are as follows:]. The base construction must have sufficient strength to withstand the maximum bearing load likely to be applied, even if the wettest of conditions. A typical construction may consist of a 150mm - 250mm layer of well-compacted graded stone (note NOT MOT Type 1). MOT Type 3 as described in Specification for Highway Works Clause 805 is suitable, followed by a 100mm minimum consolidated depth of a 70/30 Rootzone under the pavers. The loading capacity shall be 100 kN/m.
• Edging: To be formed using E10 pre-cast standard concrete 150mm wide channels. The Golpla must have fully enclosed cells to ensure there are no exposed edges within the system
• Bedding: Minimum of 100mm Rootzone 70:30 mix. The infill is a clean friable top soil and specified seed mix. Level the Rootzone to plus or minus 10mm. Consolidation is best achieved by the use of the light vibrating plate after laying the Golpla® pavers.
• Laying :Lay the pavers starting in the left hand corner of the lay-by, with the paver locking tabs facing forwards and to the right. Continue laying the pavers making sure that each is interlocked into its neighbour. Stand on the laid pavers when laying the next row. Each pallet will be numerical identified in order indicating the installation sequence of the pallets of Golpla® Pregrown. All Golpla® Pregrown units should be installed within a maximum of 48 hours after delivery to ensure a sucessful installation. For fitting around obstructions, the pavers can be easily cut with a hand saw or power cutter. Cut pavers should be nailed down using the Golpla nails. The whole area should be consolidated either with a vibrator plate or small roller
• Paving units: ['Golpla' pavers pre-grown with grass as supplied by Geosythentics Ltd]. - Bond: [In accordance with manufacturer's recommendations]. - Filling: [Supplied pre-filled and with pre-grown grass]. - Seed mix specification [Seed mix to be as per L7 in section Q30 Seeding] - Accessories: [Golpla nails for securing paving units that are cut and also all paving units at the top, bottom and along the slope].
• Notes: No recessed covers, utilitiy access chambers, Fire Hydrants, valve covers to be Page 15 of 54
