Covid-19 Update


From Friday 3 December, Porirua City is at the orange setting of the traffic lights protection framework. This means some changes to the way we work and live, protections are in place to help minimise the spread of Covid-19 in the community. Find out more

Sealing Porirua's roads

You'll find information about Porirua's annual road sealing programme on this webpage

Sealing Porirua roads

Porirua City Council maintains around 251km of roading network through an annual resurfacing programme and on-going maintenance.

We plan to carry out our next road resealing programme in February 2021, and have preparation work underway now

Chip seal is used in most instances, as per Council policy, to improve the life and value for money of our roads.  

Asphalt is used in areas of high-stress such as cul-de-sac turning circles and busy intersections.

**Note: Residents are given five days notice of planned works (which can be weather affected) and roads are swept 48 hours and then 7 days after being chipsealed to allow time for the chips to bed in.  Please treat the roads with care during this time.

Previous road sealing programmes

Road sealing was completed on the following roads in the 2020-21 programme, which took place during February and March 2021.

Moana Road, Plimmerton:

- Chipsealing between numbers 1 & 59

Postgate Drive, Paremata:

- Asphalting: SH58 to Bosun Tce

- Asphalting: Postgate Drive and Omapere St intersection

Spinnaker Drive

- Chipsealing between numbers 16 and 77

- Asphalting of the intersection with Discovery Drive

New approach to resealing intersections for 2021 programme

Asphalting - The structural asphalt being used for busy intersections in this year’s resealing programme is a “new” superior performing product that is the same as the product used on SH58 and Centerport. It has been intentionally designed to cope with poorer road subgrade commonly found on the Porirua network to ensure a longer-term result. The cost difference is insignificant, and it will result in a longer lasting finish that will be better value over its whole of life.

Chip sealing - A new approach to chip sealing some of Porirua’s less busy intersections will be used this year after a trial showed it was effective at reducing chip loss caused by turning vehicles. The new seal is a chip and sand seal combination (a type of Cape Seal), which looks lighter than standard chip seal. It involves applying a two-coat chip seal, followed by a polymer modified bitumen emulsion and a material known as AP5 or crusher dust. This material is less than 5mm in diameter. It can take time to settle and requires a thorough sweep to remove the fine chips and dust, so a standard 30km speed restriction will remain in place during that time. The new seal is more economical than using asphalt, which will still be used on key intersections. We are sharing the trial results with other Councils, with immediate interest from Wellington City.

Road sealing to optimise the life of Porirua's roading network

Porirua’s annual resealing programme looks to optimise the life of the city’s roading network through cost effective, value for money, maintenance.

The programme is an integral part of the city’s asset management strategy. It is developed from the city’s 30-year forward works programme, which is prioritised through an annual condition rating of the entire network; looking at its age, defects, maintenance costs and future maintenance risks.

Chip seal vs Asphalt

Chip seal is considered the best option in most reseal situations in terms of efficiency and function.

Asphalt surfacing is preferred in high-stress areas such as sharp turns, busy intersections and steep grades.

It is important to note that asphalt surfacing is six times more expensive than chip seal but does not give six times the life. It is also more expensive to maintain.

Chip seal consists of a membrane layer of bituminous material followed by stone chip. There are numerous types of chip seal and individual designs to determine the right one to use are done for every road section.  The design takes into consideration the current roughness of surface, the volume of average annual daily traffic and likely stress to ensure the final chip seal design used delivers sufficient waterproofing and skid resistance.
