How to Build a Deck on Sloped or Uneven Ground
Feb 19, · How to Build a Deck on Sloped or Uneven Ground. It’s not a bad rule of thumb to simply increase the depth of the footing one foot for every unit horizontal steeper the slope gets. Between and slopes, a minimum of two feet deep, and between and slopes, no less than 3 feet deep. For slopes steeper than 45 degrees, consulting an engineer may be the best choice. Jul 23, · Step 1 - Dig the Foundation Holes Dig one-foot diameter holes at the top of the slope that will hold supports for one side of your deck. Make sure these are deep enough by digging until you find solid soil. Step 2 - Place Deck Poles.

He wants a timber deck built over an existing patio, done loads of decks before but never on a hardstanding! The issue is there is only enough height between the patio and the patio door cill to accomodate 4x2" joists and a deck board 32mm on top.
There should be a fall on the patio or water would puddle on it so you could run your 4x2 joists with it and the water will run off as usual or use 3x2 and support every 4' which is easy because you essentially have a slab foundation. I'd remove every second slab, leaving the ones essential for sitting the joists on. HandyAndy - Really. HandyandyMay 31, Because there would be less mass sloe for water to pool and for the bearers to sit in. How much water could collect solpe remain on a single slab, surrounded by a 2" drop to dirt?
Presumably the patio has been how long can kidney stones stay in the kidney fine and the water has been running off as it's supposed too because it would how to start a small group ministry been ripped up otherwise.
Pulling up every other slab gives you a disposal problem and potentially weeds growing through the decking. Why bother? Just like I said. Less area for the joists to sit in water. How many more reasons do you want? Ideally, the joists would be not in contact with the ground at all, but the least contact, the better.
HandyandyJun 1, The joists will sit what is article 6 of pakistan constitution what water? When it rains chippie.
Decling it rains water will end up on the slabs. The slabs will stay wetter as a full patio area undef the decking than it would if no decking was there, and the bearers will help prevent the water from running off in the manner it did without any obstruction and with the sun.
With every second slab removed the maximum pooling will be a total of one slab in any one place. Deckin slab won't pool water. Result: Overall less standing water.
So you are saying that the original patio was built with no fall? Oh why why why must I spell out everything? Assuming the original patio had a fall away from the house. The guy is putting decking on top. That immediately will stop the sun from drying the slabs. If a fall on the decking is to be the same as the old slabs, the grooves in the decking need to run away from the house. These joists will trap water trying to run away from the house maybe all the way acrossit will not get dried by the sun.
The joists will remain wetter for longer. IF on the other hand the joists are laid away from the house and how to remove metal from eye decking across, the the fall on the decking AWAY from the house will be pointless the water won't jump what is heat rash in babies the grooves.
Removing slabs will prevent the trapping of water. Any clearer? HandyandyJun 2, Stick the decking on top. The decking will rot as quick as the bearers, plus rats love living under decking. Either put new slabs down or clean the existing. Its only programs deckkng Tommy Walsh and Alan Tichmarsh that started of the decking phase, looks good when put down until there ln and your slipping all over the place, and look at the dopes nailing chicken wire on them to give them some grip.
Best place for decking is on the fire. Cotswold BuildersJun 2, Agreed, Cotswold. Leave the existing patio slabs intact If any were to be removed then the remaining slabs would soon be undermined and unsettled by the the rainwater drainage.
Besides which: the householder might wish to revert to the original patio once he's fed up with the slime on the decking I see no need for 4X2 joists on such a firm, uniformly supported hardstanding.
There's no unsupported span to consider here, so 2X2 sawn and treated timber bearers would be just as strong. In fact they'd be stronger, because they wouldn't need the noggins that the 4X2 would need to prevent deflection Handyandy-Really, means well, and he often comes up deckking good ideas - but this isn't one of his better ones Well don't blame me when the joists how to get antivirus for free rotting, that's all.
Here, leave a joist on the patio and see how wet it gets, how wet it stays, how it soaks up the water, how quickly it becomes soft on the bottom, how soon it goes mouldy. Then imagine how that would be without the sunshine as well. I'm just saying! I fiit what I said, that you often have good ideas. But it really isn't a good idea to undermine patio slabs by removing a few, allowing surface water to creep below them.
Depending upon the treatment a joist can sit in salt water for 25 years or work in a cooling tower or a mushroom factory or in Australia. Indeed so Chippie, but don't tell me - tell Mr HA Not depending on normal building procedure treatments, it won't. Otherwise by that standard you will have to admit you've never seen a rotten joist or timber, less than 25 years old. And you can't tell me that.
Yer normal treated stuff on a bed of water staying wet will last a couple of years. Did someone mention deciing hosepipe ban? Lucia x. You must log in or sign up to reply here. Show Ignored Content.

Apr 19, · Hello fellow woodworkers! Hope all is well in these weird times!In this video " HOW I BUILT MY DECKING | BEGINNER FRIENDLY | EP#18"I will talk through all t. When decking is installed conventionally, with gaps between adjacent boards, sloping the deck surface is not necessary. Some decking products with limited drainage recommend sloping the deck frame to a 1/4” vertical per 12’ horizontal pitch. How to Build a Deck on Sloped or Uneven Ground It’s not a bad rule of thumb to simply increase the depth of the footing one foot for every unit horizontal steeper the slope gets. Between and slopes, a minimum of two feet deep, and between and slopes, no less than 3 feet deep.
The general rule for deck footings built on a slope are based on average soil conditions. So, if you have unstable soil conditions all bets are off. You will want to speak to an authority in your area. Usually a Geo-technical engineer or someone with lots of experience with building decks will know exactly what to do. The Seven Foot Rule is a great rule of thumb to be safe. It's simple to remember and for most conditions quite conservative. However, if you are on a mountainside with tons of rain in the winter months, speak to someone who is professionally qualified.
Otherwise you are flirting with disaster. As you can see in the photo, any footings on a sloped grade like this should be safe if the widest point of the footing is no closer than seven feet from the slope when you project a horizontal line from the point of the underside of the footing.
Note: The seven foot rule is only a rule of thumb. All slopes have to be examined and understood before any building commences. There are places in the St. Lawrence Valley, and Alaska where quick clay or leda clay, as it is sometimes called, is present. This is potentially a very unstable soil at the best of times.
A water laden slope would be at even higher risk of literally washing away under the right conditions. Alternatively, in mountainous terrain soil can be a mix of sedimentary layers or alluvial rock or sand.
This kind of slope is also at risk of sliding if its saturation point is reached. The seven-foot rule may NOT apply in any of these situations. The topic of foundations and how to properly support a deck over a sloped grade demands local building knowledge that you must acquire before you build or plan any light structure. On special locations like slopes or hillsides, take the time to contact your local building officials to find out what the soil is and what the common building practices are.
Obviously, a hillside deck can give you dramatic views and benefits but don't forget to consider safety in the equation. Different Styles of Footings on Flat Ground. Why Sign Up? Read Archives. I am looking to install privacy screens on my concrete patio.
