Installing a Curved Decking Area Posted on 03 Apr 11:23 , 0 comments

At EnviroBuild we are often asked how to install a variety shapes of decking.  A later article will explain tips and tricks on how to mitre boards.  However, as a majority of our customers are already very capable with a circular saw the more frequent question is can I have a circular deck.

They undoubtedly look beautiful and become a real feature in a garden.  However no amount of cutting will get a perfect curve that doesn't require finishing without looking untidy. 

Composite Decking Curved Installation

The easiest way to create a curved edge is to use the composite fascia boards. The composite fascia boards are thin and flexible enough that they will bend. The fascia needs to be screwed into the sub-structure to hold them in place, where a standard countersunk wood screw is perfect or this. Start at one end and apply a constant force, then simply work around the bend that you are intending. This is very much a two person job, particularly if the bend is acute.

Below is the finished example installed by Wild Wood at Goat Lees Primary School in the Hyperion Slate Composite Decking Frontier Range.

Thought has to be given to the sub-structure as well.  You're going to need to measure around the inside of the curve and ensure sub-structure is in place at regular enough intervals to hold the fascia to the curve.

The end result is however magnificent and can transform the look of a garden. It works with either of the Hyperion Composite Decking ranges that we stock. Below is in the Oak Pioneer range.

The only other method of curving is actually heating the boards. Due to the plastic content, they will become softer with heat, and can bend to a variety of shapes. There are youtube videos available on how to do this, however, it is technically difficult to do without damaging the boards, requires expensive specialist equipment and doesn't give significantly better results, thus we do not recommend this option.
