Installation

Property
Value
Filling Gravel up to 20mm Angular in accordance with NBS Section Q23
Grass seeding / Turfing in accordance with NBS Section Q30
Blinding and Levelling To level any possible unevenness in the base layer and provide a zone suitable for root growth when being finished with grass
Base Layer To ensure optimum drainage a layer of crushed rock should be installed. For general purpose use Type 1 is appropriate, whereas Type 3 should be used where the Hebden X-Grids are for use as part of a SuDS strategy.
