Good garden decking needs a good decking frame to match, whatever the underlying substrate. Joist sizes 47x100 and 47x150 may be strong enough for a deck frame, but not durable enough for exterior use or ground contact. Traditionally carcassing timber grades UC2 and UC3 have been used for deck framing but they do not provide the longevity required.
It is possible to use UC4 graded carcassing with 47x100 and 47x150 joists. It is vital that only UC4 joists are in ground contact because UC2 and UC3 (standard joists) are not treated for external use or ground contact. They can be used with UC4 square posts of 100mm or larger. Alternatively solid concrete blocks can be used to achieve the correct decking frame height, these blocks can be used with Plaswood plastic timber.
Plaswood manufacture decking framing made from recycled agricultural plastic. Plaswood is 100% recycled plastic and can be used in moist conditions or stood in water. The manufacturer quotes Plaswood as being 10 times more durable than timber in marine conditions.
Three sizes are available of this dense timber alternative, 50mm x 50mm; 50mm x 120mm and 100mm x 100mm.
This should allow installations to be carried out on flat roofs, solid level substrate and on uneven gardens. Plaswood cuts and fixes very much like softwood timber but needs closed spacing for supports. More details on setting out and fixing can be found in the pdf folder entitled Product Attachments
