Recommended Base Build Up for Terrabase Rustic Pathway option for light pedestrian use.
A suitable steel, wood, brick, stone or aluminium edging should be provided to ensure a neat edge detail but depending on project requirements, the Addagrip Geofabric can be used as an edging.
The maximum tolerance of the base should not exceed 3mm under a 1m straight edge. If existing sub-grade is silty, it may be necessary to stabilise it or partially replace with sub-base or granular capping layer.
If there is danger of ponding, the subbase should be laid to falls. Total sub-base depth will be dictated by loading and attenuation requirements.
