Large Marine Deck Hatches – Let’s begin first we must assess 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 can and may put membrane under any decking project to stop any weeds penetrating through, where would be the damp course levels as we do not want the deck over the damp course ideally the deck should be two bricks below the damp course. And is there any drain access points underneath the decking because these will be needing a unique decking drain cover. Always remember the decking boards go horizontal along your house. Always remember decking higher that 1.2m over walk out will be needing planning permission
Now we’ve got assessed these factors they’ll decide the height of the deck and then any special requirements that have to be incorporated in to the decking project. Estimation of materials first appraise the area from the decking i.e 4.8m x 4.8m = 23.04sq meters. Then employ this equation to calculate the decking boards needed 4800mm / 140mm (deck board width that happen to be 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 number of horizontal 4 x 2 pieces needed for your internal structure from the decking in addition to the outside from the frame i.e. 4800 x 4 = 19.2m + (8 x 4800) = 58m of 4 x 2. Add some for your cross member struts and positioning pegs (banged and concreted if needed in to the ground) about 3 or 4 4.8m lengths should suffice.
Establishing the frame this carried out near or as close to the position from the final deck. Start by cutting the ends from the required wood square this might help while using construction from the frame always cut the pieces of wood a similar length as the frame should never be square if the wood is of numerous lengths. Then join the corners from the frame by piloting the holes for your 4 inch screws to be screwed into wood. Once this is accomplished you have to receive the frame square, employing an engineers square put it in a single corner and move until square. Then screw a batten within the corner to carry the corner square make this happen for many corners. Then measure internally from your horizontal from the frame the place that the load bearers are inclined divide this measurement by 600mm this may provide you with the same spacing for your struts. Next screw theses available it’s much easier to place a length of wood underneath the frame while carrying this out to have the edges to meet. Once this is accomplished appraise the cross member struts about three feet is about right for your spacing of such. They go vertically along the deck frame stepping out then directly into enable screwing.
Positioning of the deck, get the deck into position while using help of an friend. Then start within the highest corner of the deck and bang an item of cut 4 x 2 (depending around the height of the deck cut accordingly) in to the ground with a large sledge hammer. Once done lift the deck into position and screw together with a 4 inch screw. Now work along the deck to the next horizontal corner lifts the corner and so the frame is level and do a similar. Now work along the front possess a slight lean away from your house or make sure whichever way the boards are running tip the deck and so the water runs out from the surface. Then work your way across the deck making certain that any weak point is backed up by banging a piece of 4 x 2 in to the ground beneath it. Once this is accomplished test the strength by walking along the struts to show any weak point no problem a lot of as the decking boards will strengthen the decking when they are fixed to the frame.
Right now we cut and fit the decking boards to the frame. Make sure every one of the edges from the decking are cut square before cutting to the correct length. This will aid construction and overall Finnish from the decking project. Start with a full length of decking making certain the finish 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 much better long lasting but nailing is faster and much easier. Work along the deck spacing with a 5mm nail banged right into a piece of 4 x 2, this may ensure how the gap remains a similar. Always remember to stagger the joints from the decking some other board and so the joints blend in to the decking. Once you decking boards are fitted then fit any surrounding decking boards to the edges to pay for up any from the frame work and appearance for just about any boards that have splinters and sand these down if you can.
