Approved Plan - Landscape Specification prepared by URBIS - OPW24/0110

Levels
Ensure there is no more than 2mm different in height between adjoining pavement segments, other adjoining
pavements, top of kerbs or pit covers (unless specified otherwise).

Spot levels take precedence over contour lines and existing ground profile lines.

Concrete Joints
All joints to be laid out as indicated on the construction drawings. If the location and type of construction
joints are not shown on the drawings, submit proposed location and detail of construction joints to the
Landscape Architect for approval prior to the start of formwork placement. Periods of stoppage in concrete of
3/4 hour or more are deemed to be construction joints.
Ensure that joint widths between pavers at dowelled construction joints are equal to the underlying concrete
pavement joint widths. The concrete base slab should not be designed solely as a jointed reinforced
concrete pavement (JRCP) but must be designed and detailed to avoid differential strains between the
pavers and the concrete slab. Pavers to be laid immediately following construction of concrete base to avoid
shrinkage of slab.

Expansion joints
All visible expansion joints to be 10mm wide zipped polyethylene foam (e.g. Abelflex) sealed with an
approved coloured sealant (e.g. Sikaflex or equivalent). Colour to match the lightest coloured adjacent
pavement. Expansion joints in structural slab underneath (both basement and single slab) are to be carried
through to the surface in the same dimensions.

Control joints
To be 20mm deep cut saws. Make the joint straight and true, and free from blemishes impermissible for its
surface finish class.
