A deck is a rewarding extension to any home.
The versatility of timber or WPC decking allows you to design a deck that is tailored to your home and your lifestyle. You can change levels, build extra wide stairs or even build seating around a feature tree through the deck.
Some points you need to consider:
•Make sure your deck is large enough; for example - your deck will need to be at least 3 metres wide to comfortably accommodate most sets of outdoor tables and chairs.
•Decking timber, bearers and joists not in contact with the ground should have a treatment level of H3 and posts in contact with the ground should have a minimum of H4 treatment (H5 may be required by the local authority). We recommend bearers and joists within 300mm of the ground should be H4.
•Paints and stains will reduce weathering and there are also a number of products which you can use to maintain the good looks of natural pine.
•To retain the original look and to avoid the build-up of slippery mildew, periodic cleaning is recommended. Low pressure water blasting with chemical cleaners is effective. High pressure water blasting is not recommended as it tends to fur the timber surface attracting more dirt and mildew build-up.
•Periodically remove any dirt or potting mix from board gaps especially over joists.
The basic rules for residential decking are:
1 - Any deck 1500mm or more above cleared ground level requires Building Consent
2 - Balustrades must be installed for any deck above 1000m in height
3 - Balustrades need to be 900mm high for stairs & ramps and 1000mm for the level deck area
4 - Even if Building Consent is not required, construction must still comply with the NZ Building Code
Please note: This is only a rough guide to the main points and does not cover every aspect of deck installation.
What is wood plastic composite (WPC) decking?
WPC decking is a new eco-friendly decking for outdoor use. WPC is composed of 35% HDPE, 55% Poplar and 10% additive (anti-UV, paint, coupling-agent etc.).
Why Choose WPC Decking?
Virtually no maintenance
Resistance to UV, moisture, termite, and other wood insects
No need to ever stain deck
Modern and elegant looks
Superior quality decking products to compete in retail market with imported hardwood species. Only small, round defects acceptable which must not detract aesthetically from a high class finished deck appearance.
All pine decking comes treated as H3.2.
Kwila, is a very good alternative to pine decking. It can be found in lengths ranging from 1.8 to 4.8m while most commonly available size would be around 3m to 3.6m in length. The species contains a natural resin which will bleed and discolour the timber while it is drying. Both green and dry Kwila machine and finish well. Kwila is a very stable and durable timber which makes it an ideal choice for outdoor uses.
Timber is a natural product which shrinks as it dries, so shallow cracks will develop in timber exposed to the elements.
