Rethinking outdoor spaces
Structural, durable solutions for building decks, tile or turf areas over waterproof membrane, concrete slabs, pavers & natural ground of all heignts from undwe 300mm to over 2m.
We have replaced the inefficiencies associated with customised deck design and construction with a comprehensive system that is superior in durability, moisture-resistance and performance, is cost-effective, fast and easy to quantify, quote and install. Most aspects of construction have advanced with technology, automation and high-performance materials. The traditional methodology for designing and constructing outdoor spaces – particularly low height deck
and tile structures has been overlooked. Amongst multiple problems these installations are high risk, largely due to moisture issues resulting in catastrophic remedial and compliance costs.
Solutions Overview here
• Timber deck structures rot due to moisture absorption and lack of airflow
• Deck construction methods are antiquated, cumbersome & wasteful
• The design process is time consuming & inefficient with each project customised
• Lack of automation technology & value engineering
• Architectural trends require low height decks & solution for rooftops developments
• Residential and commercial applications, load capacity of up to 5kN point load and 5kPa UDL
• Remedial social and economic costs for failed decks over membranes are catastrophic
• ‘Pods on pavers’ is not a structural solution is difficuly to level & potentially hazardous
• Ripped timber joists over membrane is not compliant in many councils
• The standard sales model from design to install makes a ‘fixed price’ difficult

With the architectural trend of deck design being low to the ground to maximize indoor-outdoor flow,
traditional timber framing is not an appropriate material to use. Timber framing is affected by moisture when
adjacent to or in contact with the ground or installed for example on balconies over membrane where the
height between the substrate and the decking is under 100mm. Timber framing requires blocking for
structural integrity which in turn prevents critical airflow. The timber naturally wants to bow and twist is
cumbersome and heavy to handle with a high waste percentage on site.
One of the primary reasons for the prolific ‘Leaky Building Crisis’ impacting the New Zealand and now
Australian economies is due to the way low height decks or tiles were installed over a waterproof membrane
– typical of balconies and rooftop spaces where the membrane had been damaged through direct fixing
the tiles or from moisture issues from rotten timber sub-structures. Adjustable height pedestals or pods are
still widely used to support tiles/pavers, but the installation method is proving very problematic as it
provides no lateral stability and it is challenging to prevent pavers from becoming uneven making the
pavers hazardous and requiring regular maintenance.
The status quo design-quote-buy-install model means every deck is bespoke and figured out on site by the
builder with no benefits of standardisation being passed on to the end-user. The ‘true cost’ of building a
deck using traditional methods is difficult to define when considering onsite factors such as incorrect
quantification, weather impacting installation times access to site etc.
