Pressure Treated Tongue And Groove Porch Decking – Discussing begin first we should look at the area is it a turf or concrete base under the decking a turf base will need to be dug off and membrane put under the decking you are able to and will put membrane under any decking project to stop any weeds penetrating through, where would be the damp course levels once we are afraid when across the damp course ideally when must be two bricks below the damp course. And will there be any drain access points under the decking because these will be needing a special decking drain cover. Always remember the decking boards go horizontal along your home. Always remember decking higher that 1.2m off the walk-out will be needing planning permission
Now we’ve assessed these factors they will decide the height of when as well as any special requirements that need to be incorporated to the decking project. Estimation of materials first measure the area of 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 that are 4.8m long) = 35 decking boards. Add a little for cuts and edges that need to be filled in. Then calculate the load bearing supports (4 x 2 pressure treated CLS) 4800 / 600 = 8 This the volume of horizontal 4 x 2 pieces needed for the internal structure of the decking together with outside of the frame i.e. 4800 x 4 = 19.2m + (8 x 4800) = 58m of four years old x 2. Add some for the cross member struts and positioning pegs (banged and concreted if needed to the ground) about three to four 4.8m lengths should suffice.
Building the frame this carried out near or as close to the position of the final deck. Start by cutting the ends of the required wood square this might help using the construction of the frame always cut the pieces of wood the same length because frame won’t be square in the event the wood is of different lengths. Then join the corners of the frame by piloting the holes for the 4 inch screws being screwed into wood. Once this can be done you need to have the frame square, having an engineers square stick it a single corner and move until square. Then screw a batten within the corner to keep the corner square do this for many corners. Then measure internally in the horizontal of the frame in which the load bearers are getting divide this measurement by 600mm this will offer you the same spacing for the struts. Next screw theses available it can be simpler to place a period of wood under the frame while accomplishing this to obtain the edges to meet. Once this can be done measure the cross member struts about three feet is approximately right for the spacing of these. They go vertically along when frame stepping out then straight into enable screwing.
Ranking of when, get when into position using the help of a friend. Then start within the highest corner of when and bang a piece of cut 4 x 2 (depending about the height of when cut accordingly) to the ground with a large sledge hammer. Once done lift when into position and screw together with a 4 inch screw. Now work along when to the next horizontal corner lifts the corner hence the frame is level and do the same. Now work across the front have a very slight lean away in the house or ensure whichever way the boards are running tip when hence the water runs out of the surface. Then work your way across when ensuring that that any weak spot is backed up by banging a piece of four years old x 2 to the ground beneath it. Once this can be done test the strength by walking across the struts to exhibit any weak spot don’t get worried too much because decking boards will strengthen the decking when they are fixed to the frame.
Nowadays we cut and fit in the decking boards to the frame. Make sure every one of the edges of the decking are cut square before cutting to the correct length. This will aid construction and overall Finnish of the decking project. Start with a full period of decking ensuring that the final meets the frame or cut the board to the nearest beam and connect the board with a Paslode nail gun using 50mm nails or pilot and countersink holes and screw the boards screwing is better long term but nailing is faster and simpler. Work along when spacing with a 5mm nail banged in to a piece of four years old x 2, this will ensure that the gap remains the same. Always remember to stagger the joints of the decking almost every other board hence the joints blend to the decking. Once you decking boards are fitted then fit any surrounding decking boards to the edges to pay for up any of the frame work and appearance for just about any boards which may have splinters and sand these down if you are able to.
