Deck Support Under Hot Tub – Discussing begin first we need to look at the area would it be a turf or concrete base beneath the decking a turf base will need to be dug off and membrane put beneath the decking it is possible to and will put membrane under any decking project to stop any weeds penetrating through, where will be the damp course levels as we do not want the deck over the damp course ideally the deck must be two bricks below the damp course. And perhaps there is any drain access points beneath the decking since these will need a unique decking drain cover. Always remember the decking boards go horizontal along your home. Always remember decking higher that 1.2m off of the walk out will need planning permission
Now we have assessed these factors they’ll decide the height of the deck and then any special requirements that need to be incorporated in the decking project. Estimation of materials first appraise the area of the decking i.e 4.8m x 4.8m = 23.04sq meters. Then make use of 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 need to be filled in. Then calculate the load bearing supports (4 x 2 pressure treated CLS) 4800 / 600 = 8 This the number of horizontal 4 x 2 pieces needed for that internal structure of the decking in addition to the outside of the frame i.e. 4800 x 4 = 19.2m + (8 x 4800) = 58m of four years old x 2. Add some for that cross member struts and positioning pegs (banged and concreted if required in the ground) about three to four 4.8m lengths should suffice.
Setting up the frame this carried out near or as close on the position of the final deck. Start by cutting the ends of the required wood square this can help while using construction of the frame always cut the components of wood exactly the same length because the frame will not be square if the wood is of lengths. Then join the corners of the frame by piloting the holes for that 4 inch screws to get screwed into wood. Once this is achieved you’ll want to have the frame square, using an engineers square place it a single corner and move until square. Then screw a batten inside the corner to support the corner square try this for many corners. Then measure internally in the horizontal of the frame the location where the load bearers are inclined divide this measurement by 600mm this can present you with the same spacing for that struts. Next screw theses in position it can be simpler to place a length of wood beneath the frame while achieving this to get the edges to satisfy. Once this is achieved appraise the cross member struts three feet is around right for that spacing of the. They go vertically along the deck frame stepping out then in to enable screwing.
Ranking of the deck, get the deck into position while using help of a friend. Then start inside the highest corner of the deck and bang a bit of cut 4 x 2 (depending around the height of the deck cut accordingly) in the ground which has a large sledge hammer. Once done lift the deck into position and screw together which has a 4 inch screw. Now work along the deck on the next horizontal corner lifts the corner so the frame is level and do exactly the same. Now work over the front have a very slight lean away in the house or be sure whichever way the boards are running tip the deck so the water runs out of the surface. Then work your way across the deck making sure that any a weakness is sustained by banging a piece of four years old x 2 in the ground beneath it. Once this is achieved test the strength by walking over the struts showing any a weakness don’t worry too much because the decking boards will strengthen the decking after they are fixed on the frame.
Today we cut and fit the decking boards on the frame. Make sure all the edges of the decking are cut square before cutting on the correct length. This will aid construction and overall Finnish of the decking project. Start which has a full length of decking making sure the end meets the frame or cut the board on the nearest beam and fasten 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 the deck spacing which has a 5mm nail banged right into a piece of four years old x 2, this can ensure how the gap remains exactly the same. Always remember to stagger the joints of the decking almost every other board so the joints blend in the decking. Once you decking boards are fitted then fit any surrounding decking boards on the edges to pay for up any of the frame work and appearance for just about any boards that have splinters and sand these down if it is possible to.
