New Sub-base with Concrete or Timber EdgingsWhere new sub-base preparations are required the area should be excavated to a minimum depth of 150mm. A minimum thickness of 100mm MOT type 1 crushed stone should be compacted and regulated with local deviations no greater than 10mm under a 3 meter straight edge.The stone levels may range between 100mm and 300mm depending on site conditions.A perimeter edging is required to retain the surface.For concrete edging, Abacus recommend a PCC edging bedded and haunched on concrete. The edging should be set to the level of the regulating layer. Inside the concrete kerb a timber edging should be fixed.For the timber edging, Abacus recommend 100mm x 50mm edgings held in place by suitably position stakes. Where the timber edging is sited within a concrete kerb the timber should be held in place by screw fixings set at 600mm centres. The edging should be set to the level of the regulating layer.

New Sub-base - Concrete or Timber Edgings
Where new sub-base preparations are required the area should be excavated to a minimum depth of 150mm. A minimum thickness of 100mm MOT type 1 crushed stone should be compacted and regulated with local deviations no greater than 10mm under a 3 meter straight edge.
The stone levels may range between 100mm and 300mm depending on site conditions.
A perimeter edging is required to retain the surface.
For concrete edging, Abacus recommend a PCC edging bedded and haunched on concrete. The edging should be set to the level of the regulating layer. Inside the concrete kerb a timber edging should be fixed.
For the timber edging, Abacus recommend 100mm x 50mm edgings held in place by suitably position stakes. Where the timber edging is sited within a concrete kerb the timber should be held in place by screw fixings set at 600mm centres. The edging should be set to the level of the regulating layer.
