Do you include the bolts with the straps ?
Yes, we do.
I bet it can probably take a similar bearing to a regular post, but what about moment / overturning? Seems like it would be pretty weak to that.
The piers with the 12" x 12" top ground plate "squeeze" the ground and have excellent later load carry capability. The piers without the ground plate have a "+" shaped load fine installed at the top to withstand lateral loads. However, in all cases, bracing the posts with diagonal bracing is recommended especially if the posts are long.
The only one I saw on your site is non frost 24" free standing, but the vid looks longer but not 4' and building off the house?
@@kurthellenberg we are selling an extension that would put you below a 4' frost line. the kit is labeled frost protected on our website and it is a combination of a 36" auger and a 24" extension. If you are attaching the structure to the house you would want the frost protected variant but if you are not and it will be free standing you can use the non frost protected. Hope this helps!
How much of load will this pier carry?
The shorter pier (less than 4') with the 12" x 12" load plate can take up 1400# in clay and 6200# in sand. I would recommend designing for 1/2 of these loads. For the pier without the plate, it has an ultimate load in non-clay soil of 1400# - 1500# but recommend a design load of 800#.
Excellent
This looks like just what I need...except in my case the wall that needs a fix is supporting a poured concrete slab porch that is above. How could I anchor the straps to that slab? Since the slab sits directly on the block wall I don't have the tension of the steel strap like you do with wood joists. Any ideas?
If the wall is just bowing and not slipping out from under the slab at the top, then he does not have to attach to the slab. If he needs or wants to attach to the slab, he could drill holes in the edge of the slab and use one of the bolts. He may get luck if the slab is 4” thick and use the hole that is designed to go into the 4” top block, if not, he could always drill another hole which I think was 7/16”? -Rich
So what if you can't access the underneath of the joist because there's a ceiling below?
Depending on the situation, the strap can also be applied to the side. We now have a few different options for joist repair if you visit our website - nolanstructuralproducts.com or you can use our contact form to send us a picture and we can provide recommendations.
little concerning that you have real photos for the metal beams and the carbon fiber... then when you go to the metal straps is a computer generated model...
You're viewing a very old video. Please see some of our newer videos for basement wall strap installations.
Discussion of cracking walls early in vid is excellent. I’d never thought of that about trees but of course it’s true: they are very heavy and forces are not purely vertical.
can you elaborate 4:25 looks like my own scenario with the exception of plumbing is on top (bathroom the second floor)
can i hav ea shower drain on top of the joist? i am working with a 32 by 48 shower base where the hole is in the middle but it is also going to be on top of the floor joist is there a solution ?
at 11 min you said 20" x 20" x 12" thick footing (where did you get the 12" from?)
12” is a safe thickness for footings up to at least 24” x 24”. The thickness of the footing is governed by the punching shear, in other words you do not want the post to punch through the footing. At 12” you are safe for smaller footings, In fact you could potentially go all the way down to the code minimum of 6” but usually I see, 8”, 10” or 12”. To determine the actual footing thickness takes a bit of work. Hope this helps.
Nice product
Getting ready to buy a home built in 1930. One long horizontal crack in basement. So this is helpfull.
these walls like many others NEED to be hand dug out, exterior waterproofing dude because that would reduce lateral soil pressure acting upon the walls and remove any possible underground tree roots AND properly waterproof all of the EXTERIOR cracks in walls!!! (backfilled with all gravel) Example-- tree limb lands on your roof during a storm and causes damage to roof and water begins to enter, what are YOU going to do? Install some braces and foam up in the attic or are you going to remove the tree branch off the roof and repair the damaged roof on the exterior? smh
Do you have anything that works for round pipe?
They show you at 1:30 into the video
Not really.. that's a round pipe with square foot welded to it. I asked about just round pipe.
@@gkogel ahhh I gotcha
Great Video thank you!! 🙏
can you notch the center of the joist if you sister the top portion ?
that’s an impact driver not a hammer drill
Very good video on explaining how to calculate column footings. Interesting product using a large steel plate.
Keep It Real Now!!! God Forbid You Question A Engineer Because They Know It All!!! ANY CRACKS In Your Basement Walls Need To Be Adressed Right Away , Because Where There's One Crack There Are More!!! That Means More Places For Water To Seap In!!! Which In Turn Fills The Blocks With Water Which In Turn Will Rott The Blocks From The Inside Out!!! Which By The Way, When The Frost Level Drops It Freezes The Water Logged Blocks!!! Which By The Way!!! As It Freezes The Ice Expands And Retracts!!! Which By The Way!!! Tends To Weakin The Blocks, Which Weakins The Tegrety Of The Wall!!! What Happens Then You Ask??? Due To The Weight Of The House!!! And The Pressure From The Ground Itself Around The Walls!!! And All The Water Run Off And Ice!!! The Walls Bow In!!! Who Wants To Just Stop The Bowing Walls??? Which By The Way!!! Is Technically A Quick Temperary Fix!!! And Yes You Can Get The Walls Straight Again!!! You Have To Dig Around The Outside Like A Water 💧 Proof!!! While You Have The Ground Open!!! What Ever Wall You Are Working With??? Start In The Corner!!! Use A 40 ton Bottle Jack!!! 2' From The Wall!!! Jack The House VERY SLOW ( Listen for unwanted cracking sounds!!! ) Just Enough To Barely Sunlight!!! You Should Have Pre -Driiled On The Basement Floor Against The Walls Every 3', 3" x 4" Deep!!! Cut Some Pieces Of 2x10x16 Blocks And Screw Them Into The Floor Joices So The Joicies Don't Roll When Jacking!!! Now!!! My Boss And I Fabbed Our Own Jack Tub That Holds Our Special 100 Ton Jack Is Specifically For Pushing Walls From The Inside!!! As You Slowly Push The Wall You Need Keep Checking The Wall With A 4' level Horizontally!!! Once The Lower Half Touches The Top And The Bottom!!! Put Your 3"x7' Beams In The Hole On The Floor And Bolt The Top Half To The Floor Joices Continue Áll The Way Around The Bad Walls!!! Don't Forget To Fill Any And Áll Cracks!!! Once You Finish The Walls From Inside!!! Go Outside While The Walls Are Exposed!!! Grind Out And Fill Any And Áll Cracks With Type S Mortar, Once It Dries, Spread Tar On The Wall, Put Visqueen And 4'x8'x2" Styrofoam!!! Where I'm From??? Inspectors Won't Let You Backfill With Dirt!!! So We Start With 2' Of Peat Gravel Over The Drain Tile, Then 3" Crushed Concrete!!! 2' Of Top Soil And Clean Up And Be Gone!!! I Have Been Doing This Since I Was 15yrs Old!!! I'm 55yr Now, I've Done Rebuilt Or Repaired Well Over A 1,000 Of These And Have Not Ever Had A Call Back!!! I Love What I Do Because At The End Of The Day??? I Know I Saved Someone's House And Or Bank Account Down The Line!!! Just Saying That There's No Way I Would Use Any Of The 3 Fixes He's Talking About, Just Pay The Extra Money A Get It Done Right The First Time!!!
can I repair 6 joists in a role using this kit?
what if you can not access the top of joist?
That strap restores "FULL" strength of the joist?
Yes, and in some cases it will actually make the joist stronger than it was in its original state as steel is much stronger than wood.
very useful knowledge!! recently renovating my kitchen, plan to run a 3" drain pipe through 5 solid wood joists of 8", the holes that run the drain pipe are over 3" Dia, so I want to use the metal joist reinforcement plate to support the joists. it is possible? Thanks
Are those straps 0.31” thick (over 1/4” thick)? They look thin but maybe that’s just for illustration?
This makes absolutely no sense ... I didn't know why I keep replaying it :)
This won’t work. You need to involve the floor system and the footing. Joist run parallel to the foundation wall and from an engineering stand point need wood blocking a minimum of 5’ back at the strap location.
Awesome. Thank you. Just what I was looking for!
Who is going to check to make sure all of these codes are followed & if they are not, what are the consequences & who enforces them?

@@nolanengineeringpllc2713 Proper proper stuff we don’t get it in the 🇬🇧definitely 10/10
I dont understand how this will keep the wall from bowing since the metal strips bend and can be cut so easily
Hey Mr Nolan do you have a email I'm a engineering technician from Trinidad and Tobago and I want to get some info
Id want that repair strap min 1/4" thick how you show it going on. Thinner, I would put it on the face over the cracked area. Steel has similar strength orientation as lumber.
Great idea.. great design.. super application.. love em'.. want to use them.. BUT wayyyy overpriced... $$$$ 👎
This was very informative... I am not ashamed to admit I too thought it was tree roots.... Glad I didnt kill that tree
Would these bring excessively notched joists in the middle to code then? Would they pass inspection in Kentucky?
James, please send us a picture of your notched joists to [email protected] so our engineer can determine if our products will work for your situation.
Liked and subbed!!! I think you will be interested in S M Z E U S.
Interesting 🤔
Well, if you know where the toilet flange or shower drain is supposed to be, maybe move or box the the floor joist!
Awesome product. What is the gauge of the strap?
It is 1/8" thick
Cool!
Excellent
Thank you for addressing this...! You can not find much on this anywhere...
Hello do the steel straps also work on a brick basement wall that is bowing? What will be installation method for this type of basement wall? thanks
The dirty little secret of basement wall carbon fiber straps is that the installers and manufacturers all warranty the actual straps and the resin, but they don't warranty the resin adhesion if the underlying CMU is wet or deteriorated. Adhesion has to exceed the tensile force of the masonry unit, which is typically in the neighborhood of 200 psi for a CMU block in good condition. It's also been proven in 20 year studies using pullout tests that the resin adhesion performs poorly at the mortar joints. Also, it's been my experience that the presence of a fresh strap or beam installation, with no changes or alterations at the exterior, is consistent with an effort to merely get through a real estate transaction, and not really solve the entire problem.
Fortunately, we no longer use epoxy resin for our basement wall straps. Apologies, this video is a little out-dated.
True. We like web trusses. Can’t beat em. And how thick is this strap? That has to be pretty strong.
Great vid 👍👍
An engineering video I can relate to. The stuff that I have seen and still see and will continue to see means that you engineers will never be out of work. Thanks.
Excellent explanation, thank you!
