✏️ Transcript of The Video
By now you know that Underpinning is a method to reinforce existing foundations. Most likely these methods of underpinning are recommended by engineers to fix sinking buildings and other foundations issues.
In California, that we have earthquakes and liquefaction areas among many other unstable hillsides along with receding soils, Underpinning may be the only salvation for your sinking home. Underpinning as a foundation repair solution, basically consists of supporting failing foundations, sinking or settling concrete slabs, all done from underneath using lots of concrete.
Among the 4 major types of underpinning, which are a pit, mass pouring, beam and base, and pile, are usually recommended to lift and stabilize existing structures, so pay attention to it. Although I will point out and explain only 4 types of underpinning here, there are many other types and ways of underpinning to stabilize your home.
Let's talk about the most important methods of underpinning:
I want to tell you the 4 most common types of underpinning because if you need to raise or repair any building, the right choice is paramount to successful outcomes. In the four choices that I’ll give you, you will find the ideal one for your situation.
1 - Pit Method or Hole Method
This is the most common and the easiest kind of underpinning. An engineer will evaluate your foundation system, and mark sections where your foundation will receive the underpinning method.
To help you understand a little more about these methods and important rules, watch below one of the videos from our CZcams Channel XPlanNation. We explain this one in detail there, with drawings and designs…
************** Watch the video here - • Underpinning Foundatio... **************
Usually, the foundation is divided into regular 3’ to 4’ sections, unless the structural engineer stipulates otherwise. Next, one section at the time is excavated under the foundation wall just above the plinth level.
This is just one shoring solution. You can use other shoring methods if you like. But following the engineer's recommendations is always best. Then, the foundation pit is dug and the new foundation is laid underneath according to engineering recommendations. Use steel, hardware, and proper Concrete PSI as per plans. The work for this kind of underpinning is done in sections.
2 - Mass Pouring Method
This type of underpinning is used in situations that require shallow underpinning but not a lot of digging. In this method, the weak soil under the surface is excavated and concrete is poured in its place to strengthen the base.
3 - Beam and Base Method
This method utilizes a traditional mass concrete base along with supportive beams to ensure the foundation is stable. The weight of the foundation is supported by beams constructed below or above the foundation.
These beams distribute the foundation weight and transfer it evenly to a massive concrete base. Engineers go balls deep into this design.
4 - Pile Method
This is the method commonly used by foundation companies that invested in the right reusable hardware.
In the pile method, foundation piles, also known as foundation piers, are installed at equal distances along the foundation to lift it and transfer the weight of the home off of the unsteady concrete. This method is particularly useful in expansive, erosive, or waterlogged soils.
Though this is a common solution performed by foundation repair companies, there is a lot of variation between repair jobs based on the type of piers used.

This guy is quite a good teacher and does it with much fun and animation. Respect

[@TheGuruKe]

One of the few interesting classes you can find out here😂 that was a nice one.

[@damilareolawaye4303]

Many thanks for the insight Chief

[@damilareolawaye4303]

Easy Sir on your style of presentation 😃😃😃

[@luisnunes3758]

Just a quick feeback: try not to take too long to jump into the subject. We come to get straight forward information not to hear stories.

The comedy routine was SO unnecessary (and not at all funny). 5 minutes in before he got to any information. I couldn't watch anymore. I'll get the information elsewhere.

[@XPlanNation]

Thank you for your feedback. X-Plan-Nation tries hard to provide excellent content, but the owner of the channel is kind of cookie when it comes to comedy… Who pays the bills, makes the rules… Not everyones cup-of-tea, we understand.

[@uNaFrAidDeSiGns]

Dood, please re edit. Great content, but its too much with the cuts and efxs.
Thanks for making it.

[@AhmedMahmoud-gy6br]

very long introduction and not really suitable here, very distracting

[@agustinaramayo6389]

Insoportable

[@jeremyperez2813]

Bro can you stop talking and explain

[@XPlanNation]

We relayed your concern to Drice and he suggested that we mentioned the existence of the forwarding features offered by CZcams. Drice has an unpredictably dry sense of humor. Don’t rely on him changing it…
