Case Study 2 - ANZ Bank, Western Samoa

BRIEF:
The ANZ Bank building in Apia was leaking.  Construction Coatings were invited by Fletcher Construction to provide a recommendation on how to repair the existing Butynol roof.  The new roof needed a grade of material suitable to heavy pedestrian traffic.

The process:

• First an inspection was carried out with Fletcher Construction

• Immediately Construction Coatings recognised the issue of traffic flow on the roof.  The roof had not been intended for heavy foot traffic but due to the social nature of the ANZ Bank team, the roof was often used for ANZ staff parties  Pedestrian traffic created holes and leaks in the roofing material

• Over time the leaks had been patched with varying results, seams which had also begun to fill with water had also been patched.

• Construction Coatings made their recommendation and the roof was waterproofed in conjunction with Fletcher Challenge.  While Fletchers provided the staff and labour, Construction Coatings oversaw the job, providing staff training and materials.

 
MATERIALS:
Construction Coatings recommended Elastodeck 5000 which is 100% trafficable to vehicle grade.  It is liquid applied which creates a seamless result and is highly elastic.

RESULT:
This was a very successful solution.  Testing was conducted by holding approximately 1 inch of rain.  No leaks occurred.  The plugs were then released and 6 inches of rain fell later that day with no further leaks.  In February 2006 during a particularly heavy rainfall when 19 inches of rain fell overnight, there were no leaks at all – a hugely successful outcome.

Construction Coatings is now looking at applying the same material to the Samoa Central Bank and Robert Louis Stevenson private school in Samoa.

ISSUES:
This was a very straight forward job but the size of the job was the main issue given the logistics of working offshore.
