Scope

For the last 9 years Asphaltech has been entrusted to maintain and upgrade the Museums many roofs, parapets and ponds. The Auckland Museum has over 5000m2 of Mastic Asphalt on the roof of this famous landmark.

1887 Roof Renewal - Asphaltech carried out a survey of an existing mastic asphalt roof that was over 80 years old. There was none or minimal fall on the existing roof and many defects were present.

Parapet renewal - At present Asphaltech had been asked to consult on the existing membrane that was applied to the parapet and propose a solution for renewal.

Cyclical maintained – Asphaltech have carried out a cyclical maintenance on this wonderful structure for many years now.

Solution

1887 ROOF - The only solution for the 1887 roof was to remove the existing membrane with great care. The roof would be replaced with new polymer modified mastic asphalt with a new solar coating to reflect the harsh New Zealand sun. Mastic asphalt was used as a screed to create falls on the existing substrate. The finished outcome was outstanding with no water ponding what so ever. 

PARAPET RENEWAL - Asphaltech suggested that the existing membrane was to be removed new falls created in the parapet to allow the water to flow and renew the copper flashing. The complete parapet is being replaced with 2 X 10mm of Pacoflex polymer modified mastic asphalt roofing. This process is going to be carried out over a 3 year period of staged construction which is easily achieved by monolithic mastic asphalt.

MAINTENANCE  at the museum is carried out by liaising directly with the Historical Architects to ensure an appropriate solution is found

"Mastic asphalt has a long life span of 60 years (source RICS). Fully recyclable, it has a low impact on the environment. Benefits of mastic asphalt are its durable, waterproof, voidless and self compacting."
