Case Study 1 - Wither Hills Winery, Blenheim

BRIEF:
Tank the Wither Hills Vineyard cellar and roof gardens to ensure waterproofing below ground.  A huge area of cellar and walls almost two storey’s high were to be buried under 6,000m³ of backfill soil.  Approximately 800m² of the cellar and 1,000m² of the 1st floor was to be tanked.
 
MATERIALS:
As there were two parts to the tanking process requiring two different methods of application, two types of material were chosen for the tanking.  Both materials have a long history within the industry and are proven.  The two products are quite different requiring quite different applications. 

• Bituthene 3,000 for the Cellar (this product has a stick on application)
• Soprema – using Soprasun 3 and 4 for the roof garden (this product is applied by being welded on)

RESULT:
In 2006 the Wither Hills project beat four other contending finalists to win the national 2006 Gold Registered Master Builders award for a Commercial and business project.  Construction Coating’s tanking has made a successful contribution to this top national accolade.

ISSUES:
This was a very straight forward job but the size of the job was the main issue given the volume of materials required.
