Viking Dec-K-ing Ideal for Learning Centre Playground

A new early childhood learning centre in Auckland had the challenge of creating an outdoor space that was suitable for toddlers, while ensuring the internal spaces below remained watertight. The membrane specified for the deck area needed to be functional while serving a different purpose than normal — a playground for children.

It was vital that the 83m² flat area was durable; ideal for constant foot traffic from 8am to 5pm, five days a week, and safe to play on — cooler under foot than traditional deck surfaces such as timber; pavers or tiles.

After consulting with a Viking technical manager, Viking Dec-K-ing (a PVC sheet membrane) was recommended as its physical properties met the unique purpose required:

Viking Dec-K-ing doesn’t retain as much heat as other materials. Seeing the space is a play area for children, the surface needs to be comfortable and grippy under foot
Viking Dec-K-ing membrane is one of the very few trafficable sheet membranes on the market
Being low maintenance, Viking Dec-K-ing is easy to clean (soapy wash with soft broom) — perfect for all the mess that tends to follow children
Puncture and wear resistant; making the area safe to use no matter the weather conditions — durable and robust all year round.

The Marsh Street childhood centre wasn’t a simple deck space; having been designed with internal gutters. For this to remain child safe, all internal gutters needed to be covered which was done with Viking Buzon pedestals supporting a narrow floating deck. This ensured a smooth, flat transition without any tripping hazards.

Viking Dec-K-ing is a complete system with proprietary heat-weldable accessories which assist the installation of the membrane; making it easier to detail penetrations and transitions, limiting human error and therefore maximising watertightness.

Additionally, Viking Dec-K-ing adds design flare to the project. The selected pattern for this learning Centre, ‘Country Cottage’, provided a sophisticated yet rustic style for the outdoor area. This warm timber pattern boasts a stylish look without the need for maintenance.

BRANZ Appraised (Appraisal No. 411) Viking Dec-K-ing can only be installed by a Viking Approved Applicator, and is backed by a 20-year product warranty.
