High moisture content which can be challenging to remove. Where recycled woods are used it is very difficult to know exactly which wood species are contained within the wood flour. The more complex structure can typically be seen in the concentration of tightly packed rings. Due to its superior toughness, Composite Prime uses HDPE in HD Deck XS and 150 as well as HD Deck Dual. Ensure that the joists supporting your decking are spaced no more than 30 cm apart, allowing for doubled joists where butt joints may be necessary. Water solubility of calcium carbonate is very low in pure water, but in rainwater that contains CO2 calcium carbonate forms the more water-soluble calcium bicarbonate allowing water ingress. Unfortunately there are always exceptions to the rule, it’s not so easy to pigeon hole timber simply as soft or hardwood. To maintain a high-quality wood plastic composite it’s vital all batches of HDPE are rigorously tested and QC’d prior to production. The width of the Wickes range of composite decking board is 140mm. Bear in mind that other decking designs will require different techniques and joist spacing. Quality composites will be lighter and have a lower density than cheaper products which are typically heavier with a high density. Countersink the screws if you are adding a fascia. From each of the four marks, use a set square to draw a straight vertical line. This outer layer is also highly resistant to grease, oil and other stains such as red wine. Drill the pilot holes using a 6mm wood drill bit. While poplar is classified as a hardwood it’s at the very soft end of the hardwood scale and is more akin to pine.

It is imperative that the hollow decks contain enough material in the right places to give enough structural strength to the product, otherwise there could be risk of structural failure. The molecular structure of HDPE allows it to have a much higher tensile strength, while maintaining its flexibility compared with LDPE, which is used for plastic bags and applications where lesser strength, but increased flexibility is required. When the boards arrive, lay them on a ground sheet and keep them covered.

This makes bamboo a very different proposition and material to timber. Measure and cut a 600mm section and mark at 300mm to show where the centre point is. Bamboo is an ingredient that’s been used in wood plastic composites for many years now. Once the second board is 75% secure, finish tightening the screws in your first row, but be careful not to over tighten. While recycled material is a responsible source of timber, it’s not always going to guarantee the highest quality required for the product.
