Appendix E. Seal types by council
As part of our sector-wide questionnaire, we asked councils about the seal types they used on their local road network. We asked councils to identify the amount of their network, in square metres, they sealed with:
- single spray seal
- double spray seal
- geotextile/membrane seal
- thin asphalt
- thick asphalt.
Figures E1 to E5 shows the results for all participating councils.
