Firstly I commend you for getting stuck in and creating a rather practical pit, you have some very handy skills well done. I would like to mention though about the horizontal forces that will apply to the brickwork sides of your pit/trench. Bricks and mortar are great in compression but not very good if the force applied is horizontal. In the case of a retaining wall, essentially what you have, the earth is going to push in on those walls and could start bowing them inwards. Your reinforced concrete at the top will help the top part of the trench from collapsing but unless it's 'tied' to the bottom reinforcing ring it wont help the walls much. Sure it depends on many factors, type of soil, length and height of wall, height of the water table (which does look very low), etc, so it might be ok for a long time. However, I wanted you to be aware because 'if' it was to fail the chances are it will be when the force is greatest on the structure, which is when your car is on top of it and you are at the bottom. A more ideal solution would have been to use reinforced concrete (vertical and horizontal steels) for the whole 'box' and ignore the brickwork completely, the steel reinforcing would have made sure that the concrete walls wont flex at all. Keep up what you're doing, but stay safe.

Yep true, good point. He can tom up the walls to make it a little safer. Will be slightly annoying stepping over though.

[@peteryao2008]

Agree. that was my concern too while admire his skills and hard working spirit. I am thinking to build one for myself in my garage. I am thinking use rebar all the way from the bottom to the top to make a cage like thing and extend the metal all the way to the other side of the runway, even if I may have to pour the concrete section by section, the metal skeleton is connected . great job and very inspiring.👍.

I was wondering about the reasons not for casting the entire box, why lay the bricks? Did have a good laugh at the “I broke the first brick!” Lol. Without having any experience in building, I was also thinking about the weak part of this structure clearly being the earth pressing in on the brick walls..

[@marcusallen3200]

Agreed. A lot of effort but not particularly safe. The walls should have been of reinforced concrete. All he had to do was cast the concrete foundation, shutter up the hole to form the wall former, insert rebar and pour the concrete in, ending up with a rigid concrete box. Additionally, as it is in the open and not waterproof, a sump or graded incline in the floor would also allow any water to be easily pumped out when necessary. Retrospectively, to avoid collapse or deflection of the existing brickwork, probably the best he can now do is to cast a 1000mm x 200mm (A142 mesh or similar depending on vehicle loadings) reinforced concrete slab (C30/40) all around the pit, to a shallow fall away from the pit, to spread the load of the vehicle and to fill the void behind the brickwork with a waterproof grout.

Great job, not many people have that kind of work ethic to dig by hand😊

[@hermitfrogovich218]

of course, because people are lazy as I said in my recent video about strawberry

[@pjmccracken]

Nice work and fair play for doing that digging by hand, that must have taken some time !! A great DIY pit which should last for many years !!

[@tcjnr82]

Impressive hip mobility… Great job on the pit.

Man ... That is very impressive work! And a lot of hard work. How long did it take you from start to end? (You just kept going and going).

Plastering at the same time as bricking!

[@gilberesrepairs]

Nice 👍

[@RobsReviews]

idk about those walls. my gut says build proper car stands , ramps, cribs or something

[@silverdragontaylir8252]

Needs roof

[@Jagersons]

How do you keep water from getting in

[@hermitfrogovich218]

If you mean spring water, when the snow melts, I don't keep it from getting in. I let it go. It's just for a month or two. Then it goes away.

[@diegosc985]

Looks too deep right, what if you get a truck in there?

[@hermitfrogovich218]

Deep? That's what my height is, so that I don't need to bend under the car. What do you mean by "get a truck in there"?

[@jg5329]

How long you worked on this??

[@hermitfrogovich218]

all summer

[@anthonykinrade8642]

Has it collapsed yet?

[@hermitfrogovich218]

Second year, still like brand new.

[@TheHalusis]

cinder blocks man

[@hermitfrogovich218]

lol, not cinder blocks, but brick man

[@TheHalusis]

@@hermitfrogovich218 i meant use them instead, with rebar. much safer. good vid tho brotato

[@hermitfrogovich218]

@@TheHalusis got it, thanks for advice 😉
