Composite Deck Board Thickness – A few begin first we should appraise the area is it a turf or concrete base underneath the decking a turf base will have to be dug off and membrane put underneath the decking you are able to and will put membrane under any decking project to prevent any weeds penetrating through, where are the damp course levels once we are afraid occasions above the damp course ideally occasions needs to be two bricks below the damp course. And can there be any drain access points underneath the decking since these will need a particular decking drain cover. Always remember the decking boards go horizontal along your house. Always remember decking higher that 1.2m over walk-out will need planning permission
Now we now have assessed these factors they’re going to decide the height of occasions and then any special requirements that have to be incorporated to the decking project. Estimation of materials first look at the area in the decking i.e 4.8m x 4.8m = 23.04sq meters. Then use this equation to calculate the decking boards needed 4800mm / 140mm (deck board width which are 4.8m long) = 35 decking boards. Add a little for cuts and edges that have to be filled in. Then calculate the burden bearing supports (4 x 2 pressure treated CLS) 4800 / 600 = 8 This the amount of horizontal 4 x 2 pieces needed to the internal structure in the decking plus the outside in the frame i.e. 4800 x 4 = 19.2m + (8 x 4800) = 58m of four x 2. Add some to the cross member struts and positioning pegs (banged and concreted as needed to the ground) about three or four 4.8m lengths should suffice.
Setting up the frame this should be done near or as close on the position in the final deck. Start by cutting the ends in the required wood square this will help using the construction in the frame always cut the components of wood the same length because the frame should never be square when the wood is of different lengths. Then join the corners in the frame by piloting the holes to the 4 inch screws being screwed into wood. Once this is done you should obtain the frame square, employing an engineers square install it in one corner and move until square. Then screw a batten in the corner to carry the corner square make this happen for all those corners. Then measure internally through the horizontal in the frame where the load bearers ‘re going divide this measurement by 600mm this can present you with the same spacing to the struts. Next screw theses available it is better to place a duration of wood underneath the frame while carrying this out to obtain the edges in order to meet. Once this is done look at the cross member struts three feet is all about right to the spacing of such. They go vertically along occasions frame stepping out then in to accommodate screwing.
Setting of occasions, get occasions into position using the help of a friend. Then start in the highest corner of occasions and bang a bit of cut 4 x 2 (depending about the height of occasions cut accordingly) to the ground which has a large sledge hammer. Once done lift occasions into position and screw together which has a 4 inch screw. Now work along occasions on the next horizontal corner lifts the corner hence the frame is level and do the same. Now work over the front use a slight lean away through the house or be sure whichever way the boards are running tip occasions hence the water runs out in the surface. Then work your way across occasions ensuring that that any weak spot is backed up by banging a piece of four x 2 to the ground beneath it. Once this is done test the strength by walking over the struts showing any weak spot don’t worry excessive because the decking boards will strengthen the decking when they are fixed on the frame.
Right now we cut and fit in the decking boards on the frame. Make sure every one of the edges in the decking are cut square before cutting on the correct length. This will aid construction and overall Finnish in the decking project. Start which has a full duration of decking ensuring that the finish meets the frame or cut the board on the nearest beam and fix the board which has a Paslode nail gun using 50mm nails or pilot and countersink holes and screw the boards screwing is much better long term but nailing is faster and simpler. Work along occasions spacing which has a 5mm nail banged into a piece of four x 2, this can ensure that the gap remains the same. Always remember to stagger the joints in the decking every other board hence the joints blend to the decking. Once you decking boards are fitted then fit any surrounding decking boards on the edges to pay for up any in the frame work and check for just about any boards that have splinters and sand these down if you are able to.
